Well, what prompted this discussion was the fact that I zapped the finals in my Century 22. It was a series of errors. I had left the drive set to full power; band was set to 10 MHz, but autotuner wa
Jerry: Thanks. I have the original breaker that Ten-Tec used on the Corsair and it translates to an Airpax "instant trip", which are scarce. The fast trip appears to be an acceptable substitute, thou
This is the quote I got from Poco for the fast trip breakers: *T11-1-20.0A-01-11C-V *@ $12.50/ea* *Parts are in stock *T11-1-5.00A-01-11C-V *@ $12.50/ea* *Delivery 8 weeks ARO The instant trip breake
No, not the crowbar, which is used for overvoltage protection, but the current sense circuit. Bob WB2VUF On 1/2/2011 3:31 PM, nl7vl wrote: The question is, how fast does a fuse or circuit breaker hav
No, not trivial to replace. The Corsair front panle has to be removed I think. Pots and switches of the correct size and ratings are hard to find. I remember years ago, Centralab had modular replacem
The RF Connection also carries 300 ohm ladder line. Walt Maxwell uses 300 ohm line feeding a 130 foot dipole on all HF bands. Bob WB2VUF 73 Rick I had more trouble with wind with TV twinlead over the
John: Not good, but the noise blanker is simple enough such that it is possible to build a duplicate on vector board. Somewhere I saw specs for a complete noise blanker on a chip. 73, Bob WB2VUF John
Gary; Thank you for that report. I run my Paragon and Corsair barefoot with modest wire antennas, so I think that the 715 might help a bit. 73, Bob WB2VUF The 715 works on ANY TT SSB radio. You will
Thanks, I think I might go for it. The audio processors in my Paragon and Corsair don't seem to do much. Would an audio generator or 'scope be helpful in setting it up? 73, Bob WB2VUF A little goes a
Congratulations on a good deal! I thought at first that you were going to say that it was your original Omni, but your story is heartwarming enough. It's a good thing to bring an old rig back to life
Carlos: To read the current, you can unsolder the red +12 V lead to the driver and final board and insert a milliammeter in series with it. This will give you total current into the board. I don't kn

It's easy enough to unsolder the wire. Otherwise I'd have to borrow a Tektronix current probe from the work QTH or bring the rig to work on a Saturday. I measured the bias voltages as they are set no
Yes, the note from G3VTT was typed on the inside front cover. In the Century 22, with key up, the finals do not receive bias voltage. The final bias is only applied when the "T" voltage is present, b
And how does it compare to "vintage" gear, like my Paragon? Bob WB2VUF On 12/4/2010 11:00 AM, Paul DeWitte wrote: The Eagle has been out for a little while now. For those of you that have one or had
Howard: L1 is used to adjust the frequency of the 9.00 MHz crystal. T1 is a 455 kHz tuned circuit. You can probably make a new one from an old 455 kHz IF transformer. Q1 and Q2 are type MPS-3693. I'm
I like that idea! Bob WB2VUF Just a thought... 'Happy Holidays' == James -K8JHR == _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.co
I want one for my Scout! 73, Bob WB2VUF The Corsair DDS is still in development, it was designed by Joe N4YG www.N4YG.com You can see how he has adapted what was originally an HW101 DDS for Corsair.
Curt: Most Ten Tec owners seem to be going to Poco Sales (http://www.pocosales.com/). They have a minimum order of $25. The breaker that you have looks like the Ten Tec 1140, which was used for the C
