Hi Drew,
I was wondering if any process has done on getting the BBS back on V/U again? I know the new control software cause some problems with the UHF receiver but I figured it has been over 2 years now since that update.
Can you shed some light here??

No progress to speak of. It turns out to be a limitation in both hardware and the operating system itself. With the other things going on with AO-51 and the low usage of the BBS, frankly it is a low priority.

I see! As for low usage of the BBS, well, most of the folks that used GO-32 either don't have 1.2g or have not been able to get into the AO-51 BBS at all since the new configuration was put in place. I have been unable to use AO-51 BBS with a 70 watts brick on 1.2g, a directives system 23 cm RHCP 12 turn helix 14.5 dBic gain, 1/4 inch heliax coaxial cable after many days of trying. I can into AO-51 using voice with no problem. I know the frequency is a little off and have tried adjusting but no luck.
I just wonder if the BBS was in V/U mode how many more users would show up. Can a schedule mode be requested for the BBS for V/U???
Oh well, as you said, it is a low priority.

V/U BBS was discontinued because it interfered with control of the satellite, so no, we won't be scheduling it without the upgrade even if requested. We have many L/U users on several continents, but it does require a very good station. The equipment you describe should be adequate...it's similar to what I use. The deviation and frequency is very important to be successful. My uplink is about 3 khz high than listed. Since you have an excellent L/U analog uplink, I'm confident the devil is in the details with your digital setup.
We've had a lot of other challenges to keep AO-51 running and healthy this year and last. I'm sorry if you don't agree with our priorities. I was working on a more comprehensive explanation to the separate identical email you sent this morning. You'll have to excuse me if I was a little kurt in my answer after you pressed the question via -bb.

Angelo, Not hearing anything but static on 7290 +/-. Might do better on 75 meters. Forty sounds pretty much dead here. Glenn
I appreciate the helpful hints. I will try it again once it comes back up on 1.2.
Again, thanks for all your efforts in keeping AO-51 one of the leading satellites to use.
My hat off to you!! :-)

Angelo, Further to Drew's comments I would confirm the 1268.703 uplink. One further hint besides deviation and frequency, is to set the TXDelay to 1000 milliseconds. This will ensure all the switches or relays in the system have settled prior to issuing the uplink packet. If you find this to be the "issue", reduce the TXDelay in 50 or 100 milli-second increments till you have reliable acks.
When AO-51 was flipped and favoured the Southern Hemisphere I was able to get acks from horizon to horizon and rarely did it double request. I use 25 watts output via about 12 metres of 5/8 inch hard-line to a 15 turn helical. With your system you should do just fine.
The other issue that Drew commented on was deviation. In the absence of test gear, a method I have used, is to listen to the audio level on the downlink, then preferably compare your TX signal level in the same Transceiver, but a separate RX will suffice. It will be very apparent if you are under or over deviating. Not very scientific, but when you have limited test gear, its a way forward. 73 Colin VK5HI.

Hello Colin,
Thanks so much for the information. I am sure it has something to do with the frequency turning. Next time the bbs in up, I will try it again.
As for the deviation, I have use this same rig and tnc with GO-32 and AO-51 when it was in V/U mode. The deviation seems to be fine. I will listen again and verify this with my HT. Service monitor is not available. Lost it in Katrina.
I really miss using the bbs. Love to download the pictures and talking with friends around the world.
Anyhow, thanks again for the tips.

Angelo
