*I don't really understand since getting active on sats again - which is why the same guys keep working each other on every FM satellite pass.* This is especially puzzling when there are rare DX and special event stations on. I was on a pass last night where there were both, yet the everyday folks were stepping on them and calling one another instead. 73, Stephen, N8URE

Fw: 2M desense on Icom IC-9700

I am having problem with 2M uplink overloading (desense) the 70CM downlink, resulting in not being able to use RS-44, FO-29, or SO-50. It is the same antenna system that I used with the FT-847 and I experienced no problem at all with the FT-847. SWR on both VHF/UHF is quite low using M2 CP yagis on fiberglas boom, 11 feet apart. I have the problem whether I use the preamps, or not. Even at 5W out, it is quite noticeable. Anyone else had this problem? KJ4EU Jerry

DOSAAF-85/RS-44
by Ray Soifer 07 May '20

I operated the 1822 pass yesterday (6 May) and worked two stations, AA2HJ and K9QHO, on CW with about 100 W eirp. Signals were almost as strong as FO-29 used to be and the apogee is about the same as AO-7. A good DX macine for those of us out of range of QO-100. 73 Ray W2RS

Re: [amsat-bb] SAT32PC question

Ted, The nasabare is only the TLE which is what's used to track the satellite. The doppler.sqf is the actual frequency and mode info for each satellite that only needs to be added to when a new satellite is added. I'm not sure where HRD gets the frequency and tone info when a new satellite is launched if you don't manually put it in. HRD works fine I guess for FM but totally blows it on the SSB birds unless they really have fixed things.

SAT32PC question
by Paul Mcl 06 May '20

06 May '20

Apologies for what could be an easy question but I am a bit new to this. Just getting the station set up at the moment. I have installed SAT32PC and have it tracking a number of the amateur satellites. I have noticed a few sats including PO101, CAS4A and 4B don’t have any frequency info shown in the window above the map. Not sure how to resolve this so any help appreciated. Thanks Paul MM0ZBH

Re: [amsat-bb] New Yaesu G-5500DC
by Nick KE8AKW 06 May '20

06 May '20

Yes. The brand new version of the G-5500 with the "DC" at the end is not compatible with anything before it, as they are now using 22V DC to drive the G5500DC rather then a regular G5500 that uses 24V AC. So that means a G5500DC motor is not compatible with a G5500 Control box, and vice versa. As for why they changed their motors to DC, I dont really know. But something to look out for sure. 73 Nick KE8AKW
