I know the "big design idea" between the Corsairs and the Paragons: conversion to 9MHz IF in the former and VHF (45MHz?) in the latter. But what are the differences between the successive models? Wha
Yes, it's all in the loop design. The Elecraft K2 is rather smart about this in moving in big steps and them tweaking the PLL reference (using a DDS) to move the PLL between the big steps. The RX320
Could you elaborate on that, Bob? Is the Paragon II phase noise much lower than the Paragon? The ARRL only reviewed the Paragon (not the P II) and it was the first review for which they measured phas
And the patrioic paragraphs ... So the bits that make the sound, the speaker and any other electronic bits, aren't actually made in the USA :-) -- Kevin Purcell kevinpurcell@pobox.com _______________
Depending on the definition of excel. The RX320 with the BCB filter disabled, the T3 input transfomer replaced (the RX320 LF mod) and perhaps a LF/MF preselector and attenuator added is perhaps the "
Personally I prefer the style of HV warning sign on an X-ray system I once saw in a lab. The power supply could provide something in the region of 10kV at 0.5A. The warning on the outside said: "Cont
Can I be nosey and ask how much it went for? Not too many of these appear for sale. (yes, this is on the list as I though others and the archive might be curious too). 73 Kevin -- 73 DE N7WIM / G8UDP
IIRC The ARRL reviewed a Argonaut II and a Delta II and found big difference between the receiver numbers (they're supposed to be identical). So there seemed to be large unit to unit variations. And

Moto will, however, own 80% of it. And usually 51% is enough depending on the contract they signed :-) The speculation (and it is speculation) is founded on the "normal" corporate pattern of of focus
John, look on the Ten Tec support knowledge base for TT using the phrase "Omni D series C". They use it for the 546C! <http://kb.tentec.com/> For example, "Identifying the Omni D series A, B or C" wh
I don't know where the Triton III went. A useful place to look for (or add too if you know the history) is http://tentecwiki.org/ Particularly <http://tentecwiki.org/doku.php?id=transceivers&s=triton
Ron is right ... there is a Triton I on the front panel ... squint at this photo from the tentec wiki <http://tentecwiki.org/lib/exe/detail.php? id=transceivers&cache=cache&media=510.jpg> Rixpix call
There's the double whammy of the low side LO, from 9068kHz to 9168kHz through the 17m band, being injected into the mixer at 13dBm and then leaking sidebands into the IF. Nothing like having a -20dBm
Does anyone out there have a schematic of the Ron-Lee AGC modifications for the Omni? I'd love to see what they look like though from the archives they seem to have lots of moving parts! -- 73 DE N7W
If you mean an AC5 tuner <http://tentecwiki.org/doku.php?id=ac5> an AC3 was a convertor module <http://tentecwiki.org/doku.php?id=ac3> I'll take it. On Nov 11, 2007, at 1:22 PM, N1IX wrote: -- 73 DE

If it's a standard electret capsule a 2k2 pull up to 3v to 12v DC is usually standard and coupling out via electrolytic or tantalum of a few microfarads is typical. Changing the load resistor varies
It does work and it's *much* better than a scramble wound coil but it still has a much lower reactance (and no loss) compared to a ferrite current balun. W8JI made some measurements on sleeve, soleno
