I think the solution for issues like this is the next time Eric does an update to the software, that he changes the Dot X or the letter. In this case that change For now 24 says, should probably have made the software 12.8a since that software iteration also included support for the FT 991 series of radios. His software is really good and his support is incredible, especially in dealing with older radios so I’m not knocking anything. Tom N5HYP

I must apologize. I failed to identify my preamps correctly. I have the ARR SP144vdg and SP432vdg. These are available for $250 for the pair shipped conus. 73, Roger W7TZ CN83ia Grid Busters w7tz.webs.com

Preamp source
by Jim White 07 Nov '19

My 22 year old Landwehr VHF preamp finally gave it up. I'd appreciate leads on high quality mast mounted preamps for VHF. AR2 doesn't answer their phone and some uni's I work with say it takes days to get a call back then AR2 didn't have the one they wanted and said they would not be making any more. And SSB USA's recording says they are only available sporadically. Looks like I can order direct from SSB in Germany so that's an option. Are there any low noise RF switched manufacturers/vendors in the U.S. these days? Where are folks getting preamps these days? Jim

Turns out HRO has some SSB units in stock including the SP-200 I wanted. So I've ordered one there. I hope HRO continues to stock the SSB units. The Minikets a couple folks suggested looks like a great option as well, especially if I was going to expand the EME array and put a preamp at the feed of each antenna. Thanks for all the suggestions.

Has anyone used a Mirage product since they became part of MFJ? If so, with what results? P.S. I talked to Jay at ARR just yesterday and he says they will not be making any mast mounted preamps. I didn't ask about other models. 73, Frank FRANK KARNAUSKAS, N1UW 3670 E. KINGLER SPRING PL.

I've always depended on ARR for preamps, but they told me material cost to build the units will run the price up too much, so they decided to stop making the 2 M preamp I need. Here is one you might want to look into Jim. I've only used Mirage for their pw amps in the past, but have been fairly satisfied with their product and repair service. https://www.mirageamp.com/Product.php?productid=KP-2/2M Dave, AA4KN ----- Original Message ----- From: "Jim White via AMSAT-BB" <amsat-bb(a)amsat.org> To: "AMSAT-BB" <amsat-bb(a)amsat.org> Sent: Thursday, November 07, 2019 4:02 PM Subject: [amsat-bb] Preamp source > My 22 year old Landwehr VHF preamp finally gave it up. > > I'd appreciate leads on high quality mast mounted preamps for VHF.

D-Star Interference to XW-2A Downlink
by Hasan al-Basri 07 Nov '19

07 Nov '19

There is a repeater on 145.670 (D-Star) in the Dallas area https://w5fc.org/tag/fsq/ It makes using XW-2A nearly impossible as it is right in the passband. Who in the world thought it was a good idea to put a D-STAR repeater (simplex) in the middle of a satellite downlink passband? Does this comply with any existing ARRL Band Plan, on other words is this a shared resource with D-Star? If so, I guess it's just tough luck and live with it. If not, perhaps someone from AMSAT can have a word with the Trustee? 73, N0AN Hasan
