What is really free anymore? Can I just "live" for "free" anywhere in the world? Perhaps. Perhaps not. Posts about Satellites and specifically Amateur Radio Satellites, Amateur Radio in general, or just NJ may appear from time to time.

Note some definitions:
About the EnhancementsThis page shows just some of the 35 enhancements WXtoImg provides: | ||||
MSA | Multi-Spectral Analysis: combines a sensor 1 or 2 (visible/near infrared) image with a sensor 4 (thermal infrared) image to create a near true colour, near visible image of the earth. | |||
MCIR-precip | Map Coloured IR with Precip: uses sensor 4 (thermal infrared) to create a false coloured image showing areas of likely precipitation. The likelihood and intensity of precipitation increases as the colour goes from green to yellow to orange to red to black to white. | |||
HVCT | HVCT false colour: creates a false coloured image by combining a sensor 1 or 2 (visible/near infrared) image with a sensor 4 image (thermal infrared) to create an image in which clouds are tinted by their temperature. | |||
Pristine | These are images as they come from the satellite without alteration. The earth appears "upside down" on Northbound passes. The two images are the two channels sent by the satellite with channel A (left) switching between sensor 1 (visible) or 2 (near-IR) during the day and sensor 3 (mid-IR) at night and channel B (right) showing sensor 4 (thermal-IR) at all times during normal operation. | |||
| Thermal | Thermal: Creates false color images using the temperatures from (sensor 4) Thermai Infrared image. This sensor covers the full range temperatures from very cold cloud tops to very hot deserts. | |||
| SST | Sea Surface Temperature: creates a false colour image by combining sensors 3 and 4 (Infrared) and using a pre-defined palette colour the image. | |||

Glossary:
cq - calling any station
k - over (your turn to transmit)
sk - out (I am finished with this contact and do not intend to transmit anymore.)
de - from
qso - a contact, or conversation between two hams
rst - readability, strength, tone. Format for a signal report.
qth - location is
pwr - power
ant - ant
rig - radio
qrs - please slow down
agn - please repeat (e.g. agn name?)
73 - best regards
tnx - thank you
es - and
fer - for
BT - break between sentences and thoughts. Also means "=". Often takes the place of a period. Period is also acceptable and widely understood.
gm/ga/ge - good morning / good afternoon / good evening
r r r - received / roger. I heard what you sent and understood it.
solid copy - I really understand you.
fb - fine business. Way of expressing happiness.
gud - good
comma, period, slash, question mark - useful punctuation marks
dit dit - two dits sent to the tune of "shave and a haircut". You can send the whole tune too.
om / yl - old man / young lady. term of affection for any ham or if you forget their name.
dr - dear
chow - food is ready I must leave.
abt - about. Use sparingly.
qsb - signal is fading
qrm - man-made interference. Usually other stations too close.
pse - please
bk - over without call signs.
Glossary of terms of questionable value that confuse newcomers:
op - operator, or name. Use name because it is clearer and easier to key.
bcnu - be seeing you
btu - back to you
hpe cuagn sn - hope to see you again soon. Usually sent at a hurried rate as a slur of one giant letter.
hw? and hw cpi? - pointless. Weird ham obsession with copying. If I send "R" assume I can copy you.
ar - end of message. Also pointless. It has some cool history from the days of military and commercial morse traffic but not really needed for a simple ham qso. Still better than hw?
kn - over to you only. Unnecessary. No one is going to disrupt your qso if you use k and if they do it is probably for a good reason.
Random thoughts:
It is best to speak in cave man english. Instead of "my name hr is", say "name name". This is a habit I have picked up from some experienced ops who are super easy to understand.
Use punctuation, with periods or BT between thoughts. Don't rush, and be concise. Leave spaces between words and sentences. Keep exchanges to three thoughts maximum.
Some ops put the sk before the final call sign.
Once you have established that you both understand each other's call sign, you can skip repeating it at the beginning of every transmission.
The order of the first three elements name/rst/qth changes all the time.
Don't be quick to end a qso when you run out of boilerplate. Keep going and you can learn more.

And now for something completely different
Morse Code/CW.
I'd like to try it on satellites, but I need to get my speed up over 10WPM.
Used to be there, but alas, old brain cells are having a tough time on certain letter combos.
Listening every morning, brings back nostalgia.

Weather Sats (again)
One application was to receive NOAA APT files, decode, and display WX pictures.
The current functioning APT satellites are NOAA 15, 18 and 19, and folks get decent
images using modest antennas.
Mostly.
Not so me, at least with that setup. I have an MFJ 2m/70cm groundplane on the corner of my roof at about 3 meters and it's, eh, ok. Not great. Plus with my neighbors house, our house, and trees around, you really need decent passes for decode anyways, but the ground plane really has some nulls on high passes, which is frustrating with the obstructions on low passes.
That said, I'll eventually get around to building a more suitable WX Sat antenna, several plans are out there.
For now, though, I really have not cracked the code between CubicSDR and any of the APT decode programs... noaa-apt seems most acceptable, but the GUI version doesn't seem to have options to decode all the various filtered images available from the download data stream, unlike wxtoimg, which apparently has the filters coded in, but for the life of me, can't seem to work with CubicSDR's data.
So, I went simple and reconnected my rtl_sdr dongle with an FM broadcast notch filter.
A straight pull of raspberry-noaa, which is a nice git repository which has pulled all the rtlsdr scripts in an easy to use "plug and play" solution.
https://github.com/reynico/raspberry-noaa/blob/master/INSTALL.md
it was literally 5 steps:
cd $HOME
git clone https://github.com/reynico/raspberry-noaa.git
cd raspberry-noaa
./install.sh
and then change some directory permissions to allow the scripts to create the image/audio directories.
Let it run.
Not perfect images by any stretch, but a lot better than the other attempts I've been doing.
Results are back to what I used to get, and about expected with my location and given antenna performance

6BTV
no radials, but the performance compared to the A99 is, like not kidding Sherlock, amazing.
I do have an issue with RFI into my home intercom/music wiring, unfortunately, especially on FT8.
And on some frequencies I have have stray RF feedback into my transmission chain between my shack RPi computers and the radio... have to work on that more, but I think I need another reorg of my cabling/wiring to straighten it out.

Hams We Are
so, a good typist transcribed an old QST editorial:
Hams we are!
EDITORIAL
APPROXIMATELY every so often an anguished member writes in to ask us how we can dare to apply the term ham to radio amateurs. Not because it is undignified, for we’re not much on false dignity in amateur radio, particularly within our own family, but because, says our correspondent, everybody knows that a ham means a punk, a lid, a poor performer, a person not fully familiar with his vegetables. Why throw asparagus upon ourselves, our inquirers ask.
Now we arise to remark that if we felt for one moment that that was a correct interpretation of the meaning of ham, it would be a thoroughly hated word at the very top of our Index Expurgatorious. We’d have a town ordinance in West Hartford prohibiting its utterance and we’d pay a bounty to QST‘s proof-readers to run down the despised term. But as a matter of fact we’re quite convinced that the appellation is an honorable one, one over which we need have no qualms whatever.
Somebody’s dictionary suggests that ham is derived from hamfatter, which was a word used in a popular refrain of many years ago. Just what the significance was is not now clear. Then there are many people who believe that the word comes from the theatrical field, being derived from “Hamlet”–because the ham actor was forever strutting the boards and reciting from “Hamlet.” For ourselves, we find a much more convincing account in an article on the etymology of the language of sports, by William Henry Nugent, appearing in The American Mercury several years ago. Mr. Nugent establishes that the United States learned its first lessons in sports journalism and sports slang from the British Isles, where early writers invented a special style and vocabulary that are still in use. Ham, says he, “began as an abbreviation of amateur to am, which the cockney foot-racers and pugilists of the 70’s pronounced h’am.”
The moment one glimpses that ham is derived directly from amateur, much is apparent that before escaped recognition. One has only to consider, for instance, the way the word amateur is abused. Webster says that an amateur is “one who is attached to or cultivates a particular pursuit, study, or science from taste, without pursuing it professionally”; there is no implication of lack of skill. Yet how often have we heard people say, speaking of many things beside radio, “Pooh, he’s only an amateur!” They are wrong, dear friends, as sure as you’re born, and they’ve merely displayed the depths of their ignorance. We accept no such connotation with respect to amateur; neither do we with respect to ham, and for the identic reason.
The word came to us in amateur radio from the wire telegraphing fraternity, where a
beginning operator was known as a ham operator. That our wire brethren, in professional scorn, employed it to mean a poor operator does not make that application correct; the misuse is, in fact, blood brother to the even more common distortion of amateur. If we borrowed the term from them we took its proper sense, and emphatically left behind any stigma of the opprobrious. There is, we repeat, nothing in the derivation of either amateur or ham to imply a lack of skill, but rather the contrary.
Hams we are, then, and proud of it!
K.B.W.
K.B.W. was Kenneth B. Warner (Secretary, A.R.R.L.), Editor-in-Chief and Business Manager and the QST editorial offices were located in West Hartford, CT at that time.

6BTV
Therefore, I finally broke down for a 6BTV, trap vertical.
More after it arrives!
Hopefully, this will be a little more reliable, more importantly will load properly and get me out on 10 PSK31, at a minimum :)

Three Down, Five to Go
Three Down, Five to Go
ok, of my original list of "things to do":
I have setup:
- my Raspberry Pi 3 B+ as the "shack computer", and have WSJT-X setup, as well as Gpredict, and TQSL (to upload LoTW entries for later sync to QRZ or N3FJP logs)
- a new Raspberry Pi 4, headless system, for Fox Telem data collection. I ran LMR 400 to the dual band ground plane and reception seems good enough to make an attempt at WX image reception again. For now, I'm letting FoxTelem run and collect data automatically when sats are above line of sight, per Nasa Keps managed by the program.
2. Getting my Az - El system working at home
3. Getting on an AO-92 L/V pass with the Alinco DJ-G7T
4. Getting my packet system (yeah that) setup again for local APRS igating
5. Getting one or more of my wire antennas up
6. Getting on mode (K? 10mtr uplink to PSAT to PSK31 70CM downlink) working

12 Tips of Learning CW
1) It's important to understand what "learning the code" really means: to become an Amateur Radio Operator who is skilled in Morse Code. That means learning a set of skills, not just the one or two skills needed to pass a one-time test.
That skillset cannot be learned by reading a book, watching a video, using other modes to talk about them on the air, or participating in online forums. While those things can help, they are not the key to learning the skills.
The needed skillset can only be learned by doing, and it takes time, practice, and an active involvement on your part. This is what makes learning skills so different from "book learning" - and why some folks find it so hard to learn skills. You have to be actively involved - it doesn't happen passively.
2) Set up a place to study Morse Code. This doesn't mean it's the only place you study code, just that it's optimized for learning code. A good solid desk or table in a room with no distractions, lots of room to write, good lighting, and a good chair. Source(s) of code (computer, HF receiver, tapes, CDs, etc.), key and oscillator. Comfortable headphones are a good idea. I recommend starting out with a straight key, you may decide to go straight to paddles and a keyer. Regardless of what key you decide to use, it needs a good solid base and needs to be adjusted properly.
3) Avoid gimmicks such as CodeQuick and printed charts with dots and dashes on them. Often such systems were designed to help a person learn just enough code to pass the 5 wpm test, but resulted in habits that had to be unlearned for practical operating. Morse Code as used on radio is sounds, not printing on a chart or little phrases. They may work for some people, but, in general, I advise against them.
Learning to receive Morse Code consists of nothing more than learning to associate a certain sound pattern with a certain letter or number. There are only about 41 of them to learn. If you could learn to recognize 41 words in a foreign language, you can almost certainly learn Morse Code.
4) Set aside at least a half-hour EVERY DAY for code practice. Can be a couple of ten- or fifteen minute sessions, but they should add up to at least a half hour every day. That means every single day, not just weekends, holidays, etc. If you can do more than a half-hour some days, great! Do it! But more time spent on one day does not give you an excuse to miss the next day.
Some folks learn better if they do several short sessions, some learn better if they do it all at once. You have to find out what works best for you.
Yes, you may have to miss a day here and there, because life happens. The trick is to keep such missed days to the absolute minimum.
5) If you can enlist a buddy to learn the code with, or find a class, do it! But do NOT use the class or the buddy as an excuse to miss practice or slow down your learning. The buddy and/or class are a supplement to your study, not the center of it.
6) Download and read "The Art And Skill of Radiotelegraphy". It's free and available from several websites. “Zen and the Art of Radiotelegraphy” is also good. Search out other code-oriented websites, articles, etc. and read what they have to say. But always remember they're not a substitute for practice.
7) Practice both sending and receiving each and every day. Most of your practice time should be spent receiving, but the two help each other. Practice receiving by writing it down and by copying "in your head". I find a pencil and block printing works best for me; you may be better with a ballpoint, felt tip, etc. Or even a keyboard.
8) A combination of the Koch method and Farnsworth spacing is probably optimum for most people. Read up on them, understand and use them – but remember they are tools, not magic. They can make learning the code easier but they will not make it automatic.
9) Discontinue ANYTHING that impairs your ability to concentrate, focus, and learn new stuff. Only doctor-prescribed medications are exempt from this rule; beer is not exempt. Eat right, get enough sleep and enough physical exercise.
10) Put away your microphones, stay off the voice radios - all of them. Besides the automated Morse Code generators, listen to hams actually using code on the air. Copy down what they send. Have Morse Code playing in the background while you do other things (but don’t count that as practice time). Learn how hams actually use code. When you get to the point where you can send and receive code, even slowly, get on the air and start making QSOs. Get involved in CW contesting, rag chewing, DX chasing, etc. Remember that you are learning Morse Code to be a Radio Operator, not just to pass a test.
11) If your HF rig doesn't have a sharp filter (400-500 Hz), get one and install it. Read the manual about how to use the rig on CW; usually the default settings are optimized for SSB. Best operation usually requires turning off the AGC, turning the RF gain down and the AF gain up. The S-meter and AGC won't work under those conditions but that's no big loss; they’re not all that useful on CW anyway.
12) Keep at it. There may be times when it seems as if you are making no progress, and times when you make rapid progress. What matters is that you keep practicing every day. Nobody was born knowing the skills you're trying to learn.
Practice can take all sorts of forms - listening to computer-generated code, listening to recordings, listening to actual on-the-air QSOs, making QSOs (rag chews, contests, DXing). Some of the practice should be things you are comfortable with, some should be a stretch. Mix it up and try different things.
Most of all: Don't practice until you get it right. Practice until you can't get it wrong.

Two Down, Five to Go
ok, of my original list of "things to do":
I sold the TAPR trakbox kit, to allow some other ham attempt to bring it to life
Instead of repurposing my win10 tablet to Linux (which I may still do at some point), I
have instead setup my Raspberry Pi 3 B+ as the "shack computer", and have WSJT-X setup, as well as Gpredict, so far.
2. Getting my Az - El system working at home
3. Getting on an AO-92 L/V pass with the Alinco DJ-G7T
4. Getting my packet system (yeah that) setup again for local APRS igating
5. Getting one or more of my wire antennas up
6. Getting on mode (K? 10mtr uplink to PSAT to PSK31 70CM downlink) working
8. Get my WX sat receiver up again, RPi and my ground plane.
Really need to finish a few things, but I feel like I'm finally making progress again, after such a long layoff.
WSJT-X Rpi 3
After some twiddling with the Radio config, WSJT-X is "seeing" and controlling the IC-706 just fine, both CAT and Audio!
So, now onto understanding a bit more about MFJ Intellituner, and then perhaps getting a bit better antenna up. But I'm back "on the air"

The Raspberry Pi
We'll see how it works out... while I was an expert in unix, it's been about 20 years since I did any serious work, other than minor "shell scripting" of various sorts (ksh mostly. lately a little bash).
So far, I've got a 32Gig SD card that boots up a later version of debian (? I think. I'm not up on the nuances of the various distros, images etc that one can load for linux generally, and the rpi specifically)
On that I've downloaded, and built, hamlib, flrig, wsjtx and gpredict.
WSJTX 2.2.1 runs, but am having trouble figuring out what ports it is using.
For this, I'd like to hook up my IC-706 using my xgcomms audio/cat cable that connects into the DNC port on the back of the rig.
Using this, WSJTX seems to "hear" when I choose a default audio port, but I've not figured out the vox, nor a rig interface, that will work.
More later as I work though this.
The good news is that the IC-706 is "up" again, and I actually copied some signals (WSJTX did decode some stations)..... I feel like the station is slowly coming to life after a long summer hiatus.

new operating position
Moving on from my trusty FT-736R, I'm going to stay "low power" for now.
Had this old desk, obtained from my father-in-law's old office. A desk he inherited from the previous office occupant.
After some sanding, a beautiful top emerged, and thus will be featured a little more prominently during radio operations.

One down, Six to go
I looked at the TAPR kit project and decided it needed to go into an experienced builder's hands, lest I ruin it.
2. Getting my Az - El system working at home
3. Getting on an AO-92 L/V pass with the Alinco DJ-G7T
4. Getting my packet system (yeah that) setup again for local APRS igating

The Radio Room is down and misc
So, time to do some summer soul searching and actually get on a few projects:
1. The TAPR controller project I've posted about before
2. Getting my Az - El system working at home
3. Getting on an AO-92 L/V pass with the Alinco DJ-G7T
4. Getting my packet system (yeah that) setup again for local APRS igating
5. Getting one or more of my wire antennas up
6. Getting on mode (K? 10mtr uplink to PSAT to PSK31 70CM downlink) working
....
I could go on, but right now, I've got to rearrange and replan and get busy!
Hobbies take a lot of WORK :)

TH-D72A, press [OK] for reset
In trying to hit the current, active, APRS digipeating satellites: PSAT (NO-84), ISS and occasionally FalconSat-3, one has to reconfigure the Path, and BPS. Using this HT there is a relatively simple menu system, and a few minutes prior to the pass, you can be good to go. Typically, I will set the APRS beacon to manual and use it to send up a first message (ok, I've read this is bad form, 'technically', from the AMSAT-BB reflector threads... so, I'll probably curtail this going forward.
We send messages to each other through these sky-digipeaters using UI / unproto messages and I have several canned (preprogrammed user) phrases to be used to "complete" a QSO.
Unfortunatly for reasons unknown, the D72A stopped sending out messages. I could beacon but not send out an actual message.
I went over every setting in detail:
300 - call sign - KA2CZU-2
301 - Beacon Type - APRS
302 - APRS Locak - OFF
310 - Data Band - A Band
311 - Speed - 1200
320 - DCD Sense - Ignore DCD (only way for me to even beacon right now)
321 - TX delay - 200 ms
380 - Position Comment - Not Emergency

390 - StatusText - set to stuff
3A0/1/2 - QSY stuff all Off
3B0/1 - Pkt Filter OFF and Type = Weather
3Cx - symbol default Kenwood
3D0 - TX Beacon Method- Manual
3D1 - Init. Interval - .2 min (tried other settings)
3E Algorithm both decal and pathing were ON... just set to OFF... don't know what these do
3F/G Smart Beacon , never have touched these
3H0 - PacketPath - *Others
3H1 - ARISS
and for the most part, everything was correct, with the exception of DCD Sense... I was told to only use "Ignore DCD" when working the full duplex 9600bps FalconSat-3 digipeater.
Fine.
That wasn't the issue.
No change made a difference, tried another ham's MC4 file and still no-workie.
What worked?
A full reset, and then restoring my (previously saved) settings.
Remember, it's [OK] to reset, if you saved your settings like you should š

Rotor Control - the "next" next step
If I ever purchase a new rotor again, I need to "read the fine print"
I forget that these rotors are used in a variety of configurations and
that they don't assume "simple 4 wire" connections.
I needed to get a cable (or special connectors) to hook up from the controller
to the rotor. - out to the interweb and ordered a pre-assembled 50' cable.
Check.
Then go to mount the rotor.
Oops, no mast mount included. Option.
Back to the interweb.
Check.
Now waiting and waiting and waiting and....
