The little filter ahead of the rest in the 9 MHz IF can be replaced by a nice, narrow filter as George at INRAD did. It helps some, but it is not much of a deal as the front end is already designed r
Good idea, I don't know who is working on anything like this. I don't know how to figure out the population for use of such things, either, since I don't know anyone with the sort of PDA you speak ab
My OMNI VI (Opt. 3)'s 500 Hz first IF filter causes a drop of about 1 1/2 "S" units when inserted into the filter chain. The other four filters cause no problems. So either the 500 Hz filter is defec
Sure sounds like a PTO rebuild to me. Does the frequency shift on receive by any noticeable amount? 20 Hz is pretty hard to detect by ear, but if you set the OMNI on some stable CW station, listen to
Opinion: 1. a belief not based on certainty but on what seems true or probable. 2. an evaluation, estimation, etc. 3. formal expert judgment. Now that is a good one. We know what an "expert" is, or a
Just to remind everyone, there is a dedicated Orion reflector on Yahoo Groups at: http://groups.yahoo.com/group/TenTec_Orion/ This might be a more appropriate place to post all the Orion-related feed
Hi John - I have a similar version of the calibrator for the Argonaut 505 and 509, the model 206A. If you are interested in a swap, let me know, I need the tuner more than the calibrator. If you want
Long story here, but there is an older ham in East Memphis, TN who has my old model 243 external VFO and he needs a bit of help connecting it to his old OMNI-D. Anyone near there feel like some very
anyone have any experience with this unit? Our local store has them on sale for very little money and if there isn't much hash I might buy it for a spare. Clark WA3JPG
OK, went and got one for $60. Small, light. Fan is not quiet. Handles 25 amps OK. Nasty noises about every 100 KHz down on 80 meters, continues up through 40 meters and peters out in strength. I susp
Mine is going back to the store today. If I lived in a place where the noise level was always S5 to S8 it would be fine, but it is not the case at this QTH. I hear the noise on 20 meters, now, since
Hi Paul Took the RS back today, got back my $59. I am considering the Astron, looking around the web for prices now. It comes recommended by many. Clark WA3JPG I generally stay far away from switchin
Hi John - Yes, it sure is a good deal, even if there are a few birdies. The birdies "move" though, right up through my favorite 75 meter frequencies, and they are S9 sometimes, really enough to make
I'm discovering the joys of a vintage Argonaut 515. I have some questions the manual doesn't answer, and I haven't found in the reflector archives: Fun rig. I've had a couple. 1. On 40m CW I hear bot
My sentiments exactly, Jim. Took mine back. Clark WA3JPG I bought one a couple of weeks ago and plan to take it back. Too much hash in the Omni VI and loud fan noise. Jim, W4VJ -- Original Message --
Aaron makes a good point, this happened to me. I did not think the supply was generating any noise till I really tested with another receiver nearby, turned the transceiver connected to SPS on / off,
Hi Tony - I know there are some simple AGC mods for the thump, but I found that they destroy the good QSK for CW. Others may have a different experience, see what responses you get. The other thing,
Hi Paul - Oh, heck, if it doesn't bother you why worry? (Remember MAD magazine and Alfred E. Neuman with his "What, Me Worry?" My dad always thought I was a little like Alfred!) I tried out a "mod" t
To help a fellow ham who is unsure about hooking up a model 243 external VFO to his old OMNI-D. Anyone near there want to lend a hand? I'll certainly return some sort of favor from the central coast
This is not quite true. It is NOT the "computer." I have had Linux systems going for months (some for years) with plenty of action and no reset required. It is NOT a "computer" problem as much as it
