XW2D satellite problem
by alex weimer 05 Jun '19

05 Jun '19

I was on XW2D at1401 utc pass and experienced extreme intermittent signals on the downlink ! Every few seconds I could hear myself , then would be cut off in mid sentence. K9VSW was also on but had the same problem. I would hear his signal , then he would be cut off as well. Signal when present was strong but there is a definite problem in the satellite JACK KC7MG

Or could it be a problem on the ground somewhere in the footprint de-sensing the satellite receiver?

I’ve been using the M2 Antenna model 23CM22EZA with good success. It has a 70” boom and is rear mounted. Very easy assembly. Ron W5RKN

Any satellites using 13cm (2.4GHz) for downlink??
by g4bbh＠btinternet.com 04 Jun '19

04 Jun '19

Does anyone know if there are any satellites using 13cm for downlink, probably for telemetry. I have an uplink system for QO-100 but am curious to see how it would work on some potential downlink. Richard(Dick) G4BBH --- This email has been checked for viruses by AVG. https://www.avg.com

Last time I bought one, a 55L in 2011, wasn't the company in Maine? It was, I think an engineering spinoff of Cushcraft. Is this true... 73 Jeff kb2m -----Original Message----- From: Mike Seguin [mailto:[email protected]] Sent: Tuesday, June 4, 2019 6:18 PM To: jeff griffin Subject: Re: [amsat-bb] 23cm antenna for L/V You can't go wrong with the D/S antenna.

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
