boys and girls. any one by chance have a pdf copy of the 255 power supply? that's the supply that went with the omni a/b/c brown with a silver ring around the edge the obsolete manual page from the t
The power supply has an internal fuse. The over voltage crow bar more than likely fired and took out the fuse. Open the case, search for a fuse on the back were the transistors mount to their heatsin
Without digging into it deeper, unplug the pa from the driver board and see if the 2 watts you're seeing is the driver and not the PA. You need to reroute the driver to the filter board or terminate
Scott, Rick's going down the right road. I too suspect the PA is kaput but I've been fooled before. I recall I was working on a trition 4 and had very low RF output. Everything seemed to be just fine
yup! In fact, I'd drop back a few more stages just to be sure. Look at the TX mixer 80453 and ensure you have enough VFO input from the VFO amp and enough LO input. Make sure you have the "T" voltage
Scott, that T voltage is okay do you have the tD voltage on low level driver? Should be about 4.5 volts or so mike _______________________________________________ TenTec mailing list TenTec@contestin
Jeez, Scott, hope you don't work as a car mechanic. You need to set back and think before unsoldering any more parts. Here's what we know 1. there's no output from the pa 2. there's no output from th
Rick, Scott, is right. Although you are getting two watts from the PA, you need to have more from the LLD. The fact that you're not drawing current indicates you're not making the PA work. If you wer
Rick, That axiom came from me. I'll dig out one if my omnis and take some readings. I didn't want. Scott digging into the PA just yet and subing a known working PA would have acknowledged he has trou
That's true, Art, but without drive from the low level driver there's nothing for the PA to amplify. Nothin' in nothin' out. Mike wb8vge Sent from my iPhone __________________________________________
Oh yeah! I still have my argosy II. I think ( my opinion) that this radio was one of the better designs form ten tec. It had enough bang to work the world. Was battery friendly and when condx were ri
Actually, you'll learn more about how things work when they don't work. First. DO NOT DIDDLE the coils on the band pass board. They rarely fail and they are as broad as a barn door. The alc is derive
Scott, Rick, Good going Scott... Now, I'm just wondering here. Like Rick, I thought at once the crystal filter was fubar. Then I sat back and tried to remember when the last time I saw a bad filter w
rick, didn't like those big storms, huh? I'd love to see one, but not necessarily coming at me. I was thinking of the omni d (and not a triton VI) that he had and if it had the optional 1.8 khz filte
Scott, You see why that was such a head scratcher for me. Rick may have seen a filter go bad, but since TT uses the filter for rec and TX, and the rec worked just fine. There's something else (no kid
russell, Jerry is right. Let me toss in a few words here. Depending on what you're planning to do with the scope, you can use a cheaper 20 mhz to 40 mhz scope with great success and a lot less money.
Yup! radio shack dosen't sell them anymore, but you can get a nice fluke or something like it at lowes or home depot _______________________________________________ TenTec mailing list TenTec@contest
Scott, That's exactly my feelings, too. Now, save your beer money and get a good counter, You'll need one to get the carrier generators back where they're suppose to be. Good job... enjoyed the ride
Hi, a Fluke Meter scope would be a great idea. 40 mhz bandwidth and handheld/battery operated. Not cheap, but small mike, wb8vge On Feb 19, 2012, at 4:24 AM, Rick - DJ0IP / NJ0IP wrote: _____________
