ESR can be thought of as a resistor in series with a capacitor. Ideally, a capacitor would be purely inductive, with no resistive losses. ESR should be constant, regardless of frequency, INMHO... for

I believe I read that all manufacturing was going to be done in Tennessee. I'd imagine part of the economics would be to reduce upper management to avoid duplication and to reduce costs. That happens
Resolution in a counter is secondary to its internal time base accuracy. There are a lot of cheap counters that have time base references that are worse the the master oscillator in the Ten Tec. Just
I found an extra Ten Tec manual in my files; it is for the Omni A and Omni D. There is some factory paperwork for the series B modification included, There are other misc. pages included. Manual is i

Bud I am sorry, but it was sold yesterday and is on its way to a new owner. I posted a "sold" reply, but it ended up being split from this topic. Pete _______________________________________________
Even the Paragon had better synthesizer phase noise spec's than many of the imported radios of that era; and by several dB. Not too shabby. I run both an Omni VI and Paragon II and I've been pretty h
One "benefit" of being an old fart is a severe loss of hearing much above 2.8 kHz... if there is any hiss above 3.4 kHz it is out of my hearing range... LOL. I probably can sell some of the analog au

I have a few spares in the drawer; they all appear to be wired as ladder filters. The only exception I recall seeing, and this is off topic for the Omni VI, is the 6-kHz filter for the Paragon. It ap
One of the reasons I've stayed with my Omni VI and Paragon II is because they are so easy to work on; and most of the analog devices are still quite common and available. There aren't many exotic par
I'm thinking of upgrading my Omni VI to an Option 1. I know four front panel button functions are changed, but I can't find out exactly which ones are different. Can someone tell me what changes are
Does anyone know the frequency for the ovenized oscillator (or TXCO) in the Omni VI? I suspect it is 20 MHz, but I can't find the oscillator frequency listed in the manual. I noticed that the FT4 sta
Thanks for the information... Now that I know it is 20 MHz crystal, I'll watch for a high quality 20 MHz modular oscillator on eBay. Since the original xtal oscillator can easily be converted to buff
If it was working, and suddenly died after you have opened the case I'd suspect one of the cables that controls the relay selection for the band filters. 88% percent chance that reseating cables will
It might be useful as a roofing filter for an Omni? Pete _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
It is a four pole filter that was replaced with an eight pole. I haven't seen many for sale in the past. Four pole filters are used for the roofing filter kits for radios that have a 9 MHz first IF.
Does anyone have a junker Omni VI option I parts set? I am looking for a uP board with the option 1 chip upgrade. I want to upgrade my Omni to at least the option 1 level. Thanks pete _______________
I got mine from W5CIA.com (for my 705 mic.) Same price as TenTec was asking. I am slowly suspecting they dumped a lot of old support inventory. I read a post from someone who needed a part for a RX42
