Thus, I finally decided to bite the bullet and get a new rotor, for the sake of sanity and time, a Yaesu G-450A
If not, then need to get another controller to finally allow some automation in the shack.

Rotor Control - The next step
ok, so my steal of a buy U-100 has started to act up, along with the manual controller.
Thus, I finally decided to bite the bullet and get a new rotor, for the sake of sanity and time, a Yaesu G-450A
The goal is to finally get around to building the NOS TAPR trakbox kit I bought a couple of years ago and see if that will work to control my KR-500 el rotor and this new AZ rotor together. Should be doable.
If not, then need to get another controller to finally allow some automation in the shack.

Fox In A Box
Fox in Box... no, not a Dr. Seuss rhyming story, but a pre-configured software distribution of the fox satellite telemetry software.

Building The Fox-in-a-Box(FIAB)Raspberry Pi Telemetry Station,
Burns Fisher, WB1FJ ,Chris Thompson G0KLA/AC2CZ
I really don't know the full history here, but I put together a 7" screen, Raspberry Pi 3, RTL-SDR receiver, and this pre-configured SD card containing an image that was essentially plug-reboot-and-play.
I originally hooked this up to my 2m/70cm MFJ groundplane, but that seems to have been compromised and does not deliver a strong enough signal. Not sure of the coax has been damaged but I noticed a degradation of signals first when I had my HP Stream tablet setup to receive NOAA WX images. Using this, I had only been able to pull maybe a dozen packets a week with FIAB.
Right now, I've shifted to a fixed orientation of my elk log periodic, just pointing NW at around 30 degree elevation, and am picking up dozens of packets a day across AO-85, 91 and 92, ... I think I picked up 1 packet from AO-95 when I caught a good pass and tracked the satellite directly by hand.
Eventually I'm going to change to yet another antenna and computer controlled tracking.
To that end, I'm putting my gasping U-100 az rotor to bed. Both the manual controller and the rotor itself need serious troubleshooting, and I just don't have the time. These will go into storage until I retire and can take on the project of fixing them. In the meantime, I ordered a Yaesu G-450A to go along with my nicely working Kenpro KR-500 elevation rotor.
Next up after getting that working will be to finally try building the "New Old Stock" TAPR Trakbox kit I purchased last year (was it last or 2 years ago???).
In the meantime, my current Fox Telemetry standings are:
#333 KA2CZU
and the last sat I collected data on was:
AO-92 (Fox-1D) | latest spacecraft health | Camera Images
Frames: 65,175 - last 24 hours: 6,819 - last 90 mins: 867

Happy Sat Hunting everyone and 73!
