I once had the original Paragon which I used for Army MARS phone patch network operations during Gulf War I. A good radio for MARS / EMBASY and other legitimate operations outside the standard amateu
Gene, I recently asked the same question and found the board at http://home.earthlink.net/~wd7s/hv-2.htm . Its board only with a parts list and instructions but well worth the $45 for the high qualit
During the past weekend I participated in the phone Sweepstakes and observed high VSWR on my OMNI-VII while driving my Titan 425 using the published settings for 75 meters when operating between 3.8
Jim, I believe you have the answer as my TITAN 425, S/N 425-00516 (labeled as an export model) was sent back to TenTec for warranty work and upgrades shortly after I purchased it new from AD0S. The T
I use the recommended (by TenTec) method of tuning the TITAN 425.... alternate TUNE and LOAD for maximum power out for a given drive, increase/decrease drive and adjust TUNE and LOAD for max power ou
There are no individual tuned input matching circuits on a Titan 425. Basically the exciter drives the cathodes of of the two 3CX800A7s. The recommended feedline between the exciter and the amplifier
After careful review you are correct ("a rose by any other name is still a rose"..W.S.). 73 es DX, Gary - AB9M The manual I have shows individual input circuits called low pass filters on the input l
I'm probably missing something but it appears to me the only difference between the 75 and the 80 meter switched components is at bandswitch S1B where C19 (150 mF ) is switched out in the 75m positio
right C 18 not C 19..... using the 75 m switch position the LOAD control is always at 10 or full mesh (not enough total capacitance)... using the 80 m switch position the Load control is at 2.5 or so
My Omni VI+ which I sold last summer apparently had this symptom on one band and was sent to TT by the new owner for repair of the band pass board. 73 es DX, Gary - AB9M My OMNI 6+ has a power issue
Wayne, He didn't say how much to repair but I'd bet by the time you pay to ship it to TT, tech labor, parts, and return shipping, you'll have $150 invested. Here is the relevant part of the message I
In this case (my old OMNI VI+ after I'd sold it and the new owner used it for several months) it was a 20 meter problem. The OMNI VI+ I had was ordered from TenTec in May 2000. The OMNI VI+ was disco
Yes, the OEM ICs being out of production was one of my reasons for selling my OMNI-VI+. But there should be a replacement solution even if its a new small board with several PICs to accomplish the sa
I see no apparent problems with my TITAN 425, but after more than 20 years of excellent service, I thought it might be a good time to recap and bought the HV-2 board from WD7S at http://home.earthlin
Jim, I agree with you on the "If it ain't broke, don't fix it." ..... What I am trying to do is have the replacement board on hand and built for a quick swap. But I was trying to find out if anyone h

If you use a panadapter, its fairly easy to see when you have the signal tuned in properly. I use a FLEX-1500 in panadapter mode as the sub-rx (N4PY mod) for my TenTec OMNI-VII and slave it with DXLa
Recently I experimented with the TX equalization on my OMNI-VII by attenuating the lows and increasing the highs. What I found was, it didn't help, at least in contests it didn't, even with the amp o
A couple things to consider when using the Corsair / Corsair II as a reference... they were the last PTO radios made by TenTec as well as there are no DSP or other digital circuits in the signal path
Re: the Corsair II AGC.... it is audio derived AGC if I'm not mistaken so the settings of audio BP Filter, audio Notch, ATTN, RF Gain, and AF Gain do make a huge difference. I have the optional (addi
