Cushcraft dual band Beam
by Robert Bruninga 29 May '19

29 May '19

Any success with a cushcraft A27010S dual band beam? Just got a new one and it tunes up perfectly to 1.1 SWR but only at 150.1 MHz. Nothing we do with the matching network can lower the frequency to 145 MHz where it is off-scale high SWR. We now added 1/2" sleeves to the driven element and threaded on #10-32 nuts on the end of all the wire elements to lower the resonance, but the best is still only at 148.2 MHz. Am going to try extended the two piece boom an inch and lastly will try to extend the matching element. Just wanted to see what others did to make this beam usable. Bob, Wb4APR

Hi Rick and all, any updates on this sat? Is it still functioning as a digipeater like ISS?

By accident I deleted my recording of the AO-91 pass on Friday May 24 at 19:57 UTC. I know some of you have been very helpful in the past when I pull a bonehead move like this. Does anyone have a recording of this pass or can tell me where I may find a recording. Thank you so much! 73, Bob N6REK

Re: [amsat-bb] FW: EA Antenna Duosat 'arrow style' hand held
by Kenneth P Alexander 28 May '19

28 May '19

No word on performance, but I'd be willing to bet it's as least as good as an Arrow. It's expensive compared to an Arrow, especially an Arrow with no diplexer, but I'd still love to try it. I've never been fond of the way Arrow elements screw together to mount on the boom. This is much more robust, and they can be removed with an Allen wrench. The biggest disadvantage I see is that it doesn't look like you can connect coax to it with BNC connectors. It appears you have to strip your coax cable and attach the leads to a pair of screw terminals. That's a potential point of mechanical failure and water entry if you don't seal and secure things properly. 73, Ken , VE3HLS On Tue, May 28, 2019 at 8:58 AM Ted Krempa via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > > > Whilst perusing the new DX Engineering catalog, I see a new ‘arrow style’ > hand held using loops and supposedly weighing only about 1 ¾ lbs.

Worked through AO-7 this morning...
by William Herzberg 27 May '19

27 May '19

Hey all...I noticed on my tracking app this morning that AO-7 was making a 40° pass, so I figured I'd give it a try...I set up my radio with the frequencies...And, lo-and-behold, I was hearing my downlinked signals...Right where it was supposed to be...I first sent some CW...Then went to voice...I did hear a station call, but it was near los..So I don't copy them...Last time I sent any signals through ao-7 was over 40 years ago...I made over 600 contacts through AO-7 & AO-8...I had an old KLM MULTI-2000, put out about 10 watts...I used home-made 10m, 2m, & 70 cm turnstiles...I had a 70cm down converter, with preamps for all three...I currently have a TS-2000x...My antenna is a 2m eggbeater....I'm using an mfj duplexer, for both uplink & downlink...It works well on both the analog and fm birds...I plan on getting a 70cm eggbeater soon...But it seems to be working fine with the single antenna...

FT991A and 9K6 FSK satellites
by Gustavo Carpignano 27 May '19

27 May '19

Dear Group, I'm using the UZ7HO high-speed sound modem, with an FT991a. While I can receive the satellites in 9k6 FSK without problems whenI transmit, it is not expected that the modulation does not deviate enough. Someone with experience in the FT991 to give me a clue? Regards. Gustavo, LW2DTZ
