Alcohol/tri-flo is mentioned in this thread: http://lists.contesting.com/_tentec/2010-03/msg00357.html but not sure if it received a second thumbs up 73, Barry N1EU
That seems a bit harsh. I was a serious contester in a previous life and used that stock second receiver all the time from 2004-2008. Yes, the stock subreceiver had some issues with very strong signa
You'll need both a serial port and a sound card. If they're not built into your laptop, you'll have to provide via external USB devices or ham interface accessory. Barry N1EU
Great comments Mark! For many years I was very active on 160M cw and I found that the Orion, Orion II and RX366 receivers differed somewhat in their ability to handle s9++ signals, which were encount
I believe you're going to find the filter shapes about the same across the firmware revisions. That was one thing that I don't think got touched as the Orion evolved. fwiw, I was a beta tester from t
That's all you have to do to effectively accomplish phase locking. If there's no beat tone heard over time when the two receivers are tuned to the same freq/signal, then you have essentially accompli
The reason a lot of people preferred version 1 firmware when version 2 came out was because the version 2 firmware was a train wreck in SO many ways. and TT struggled mightily for a long time to fix
I have one Bourns 128 PPR optical encoder still available - a replacement for failing Omni VI/VI+ tuning encoders, main or RIT. It features 1/4in shaft with 3/8 X 3/8 bushing which is what the Omni u
fwiw, there were definitely two different boards used in the life of the 563/564 - early board used leaded parts and later boards used SMT. 73 Barry N1EU
That also has the 81602 PCB. But it's funny, those are definitely MY hand written notes on the 81602 schematic in that PDF. How did THAT ever find its way back to the Web site? ;-) 73 Barry N1EU
That manual PDF is dated 2/94 and denoted as 4th printing. I've seen Omni VI units with serial numbers as early as 4/92. So somewhere out there are earlier versions of the manual. 73 Barry N1EU
Bob, perhaps you can either scan or take photographs of the IF/AF section of your manual and email me the files. I will upload so everyone can access. 73 Barry N1EU
Thanks Bob. This clears up the mystery. Greg (and everybody), the 81597 is the TX AUDIO BOARD, NOT THE IF/AF BOARD. Greg, you are looking at the wrong board. 73 Barry N1EU
FYI, I still have two Omni 6 VFO encoders left Bourns 128 PPR optical encoders - these are excellent replacements for failing Omni VI/VI+ tuning encoders, main or RIT. They feature 1/4in shafts with
Stan, to get rid of the residual hash do one of the following: 1. assure you have the computer chassis and Omni 6 chassis properly bonded to common station ground. 2. put an audio isolation transform
