Wanted: G-5500 motor
by Paul Baldock 03 Jun '19

03 Jun '19

I'm looking for a motor from a G5500. Its for the elevation section, but I would guess the azimuth uses the same motor. I have a short on one of the windings, so actually all I really need is the winding assembly. Does any body have such a thing surplus to their needs? Thanks - Paul

help with Rot2Prog USB controller for new Alpha-Spid RAS
by Bob KD7YZ 03 Jun '19

03 Jun '19

I just received my new (additional) Spid RAS. This Spid Az/eL WILL strictly be for Satellite work here. At the moment I have only the included USB Rot2Prog controller. Manually the Spid works through the Rot2Prog's (cheap) controller, Arrows, just fine, in both Az and El. I want to have PstRotator program control the Spid. But I see that the only new Port is Com2. I do not see an Elevation Port when the Rot2Prog box is connected by USB to the win-10 box. How to find both ports from one USB cable off the Rot2Prog Spid controller so I can do some tracking ? thanks -- 73 Bob KD7YZ AMSAT LM #901

SatPC32 Antenna Swapping with SDR
by Lists_01＠kk9t.net 01 Jun '19

01 Jun '19

In reading the SatPC32 manual, section 3.C.bb, I see that SatPC32 provides an automated way to switch the antenna feeds by outputting a high or low on the DTR pin of the radio 2 com port through a transistor to switch a coaxial transfer switch. Is there any other way to do this if you are not using a traditional serial port but USB ports or virtual ports? My setup has a Yaesu radio for TX and an SDRplay for receive. When switching from V/u to U/v, it is necessary to swap the antennas and I would like to do this automatically with a coaxial transfer switch. As above, SatPC32 can do this in automated fashion. However, I am not using a DB9 com port for either radio (USB or internal ports only) and am trying to figure out how to get access to this DTR signal to use it for the automated switching. Has anyone used an SDR for the downlink and set up automatic antenna swapping and if so, how was it accomplished? Thanks, Tim KK9T
