Re: [Elecraft] Transverter question

Peter, The XV144 was designed when the K2 was the primary intended driving transceiver (the K2 did not tune above 30 MHz), and the XV144 design point was primarily for CW and SSB operation on the low end of the band. Since the K2 did not tune above 30 MHz (and did not do FM), there was not

Re: [Elecraft] Transverter question

The transverter range depends solely on the IF range. I use DownEast Microwave transverters and they only cover 2 MHz of the band because that is the coverage of the K3S being 28 - 30 MHz. Yes, one can get a different crystal for the DEM to allow covering the upper end of the 2M band {146 -

Re: [Elecraft] RFI in audio chain

Jan The easiest, quickest and cheapest method is to wind yourself an “ugly balun” in your coax cable line. It must be located OUTSIDE your shack to choke the common mode currents from entering the shack. Wind about 15 - 20 turns of your coax on a 6” PVC pipe. This will give you about 2500

Re: [Elecraft] RFI in audio chain

I don't like 'ugly baluns', especially for the lower bands. If you do use one, you should wind the coax as a single layer solenoid, not a "hank" of coax. Also, as someone else suggested, you need a large number of turns for it to be effective on 80 m. Vic 4X6GP/K2VCO > On 23 Nov 2015, at 2:32

Hi I am a real newbie searching for someone in the Orlando area (I live just south of Disney!) who owns a K3S and who has the patience to chat through the things I need to consider in setting up a shack for a soon to be acquired K3S!! All help small or big would be greatly appreciated. I have

Re: [Elecraft] Stereo Speaker for K3

Steve, With audio, you can forget about matching impedance, it is the voltage that matters. An audio amplifier will operate into a 4 ohm or a 1000 ohm load just fine. With the 4 ohm load, power is required, but for a 1000 ohm load, not much power is necessary. But more direct to your

Re: [Elecraft] OT: Bird Wattmeter "meter failures"

Ron mentions various well taken points regarding the Bird 43 meter series. This also applies to almost all watt meters as well, and that is the power calibration is relative to a 50 ohm load only. Any other load Z will introduce errors in the meter accuracy and indication. At the same time,
