Hi Bob, Think I'd rather have a complete Collins 618T-3 outfit. At least with that, one can operate SSB and realise the 9dB worth of "Kilowatts from Heaven" in half the occupied bandwidth, compared t
Hi Don, I can confirm your success with DeOxit. Recently, I applied Caig Labs' DeOxit and ProGold to all internal connector pins in a 20-year-old Cushman CE-31A FM Radio Test Set. This treatment clea
Hi Stuart, Not to argue the toss, but... In all my 35 years in the international telecom industry, I never ran across dBmw. All our voice-frequency (VF) level meters were calibrated in dBm. 0 dBm = -
Hi Stuart, Yes, I know what you meant. It is just that all the years I spent doing standards and compliance engineering in the telecom industry have made me a stickler for correct terminology in unit
Hi Paul, You made an interesting point. A brief Google search did not reveal any specific reference to the historical evolution of power metrology at Bell Labs. I suspect that in the days before trac
Hi Ron, It hurts to admit this, but I believe that in the matter of CW capability we are up against the ugly realities of the marketplace. The amateur segment is only a part of the major Japanese rad
Hi Bob, <<... what would happen if the core hardware pieces were made available along with source code under modified public license...>> But this leaves unaddressed my questions as to who would deve
Bill, Carl is correct. The 14 kHz analogue IF signal enters the ADC, which converts it into a digital bitstream. The DSP processes this bitstream according to algorithms stored in firmware; one of th
Paul, Have we not overlooked the diameter, pitch and offset of the case holes? (Memories of S/Line...) Cheers for now, 73, Adam VA7OJ/AB4OJ --Original Message-- From: tentec-bounces@contesting.com [m
Hi Duane, You have stated it very succinctly; technology, like time, moves on. A couple of sayings come to mind: "In technology, there are but two degrees of freedom; forward and down. There is no ba
Hi Carl, Just curious - is it possible to unlock that restriction for Canadian and European users? We have no sub-band restrictions by emission type in Canada. For example, I am allowed to operate SS
A number of general questions arise out of this impressive list of "wish list" items: 1. A substantial engineering team will need to be assembled to develop all these radio models, features etc. RF,
Pete, I just read the warning in the Orion user manual against inserting a mono plug in the headphone jack . Please DO NOT PLUG A MONO PHONE PLUG, (two-circuit) INTO ORION's FRONT PANEL PH JACK.... A
Grant, << The VBT stuff on Yaecomwoods is second best, at best. >> The Twin Passband Tuning on various Icom transceivers, including the IC-781, IC-756Pro and IC-756Pro2, allows the operator to shift

George, Paul, ITU-R Recommendation M.1173 (technical characteristics of HF-SSB transmitters for the maritime mobile service) is revealing on this point: 3 The transmitter audio-frequency band shall b
no....actually HRO's price of $2539 for the 756Pro II (even including the free PS125) is in line with the price I paid for mine at Dayton 2003. Traditionally, Icom start discounting a radio when they
Hi Stuart, Sorry - "the old-fashioned way" is no longer cost-effective. Silicon, software and numerically-controlled board build/assembly are so much cheaper these days than gears, slug racks, cams,
