5th place QRP with K2 #2154. Shunt-fed 22 meter tower and K9AY loop array for antennas. #2 QRP multiplier total, way behind VY2ZM. Gathering mults is the only way I can compete from Arizona, where it's a long way to the 160 meter population center. See you in the next contest. 73 Gary, N7IR

Re: [Elecraft] Making a K2/100 Cleaner

Jim, Read the following document, which might help. There is a spur generated on 80 meters in some KPA100's caused by a resonance in the TR switch components. Easily fixed with a 1K resistor soldered across one of the inductors. Won't help 40 meters though. http://www.elecraft.com/manual/E7400

Re: [Elecraft] [k3] Isotropic Antenna - Isotron Antenna?

Just a wild guess but I think you meant an Isotron Antenna. You’re better off with an end fed wire and a tuner. It’ll work the same or better and be far cheaper. Mobile whip antennas are another less expensive solution for your location. 73 Gary, N7IR I live in a

Re: [Elecraft] K144XV on digital modes - disappearing power

This problem has nothing to do with setting the proper ALC level. Both KB7Q and I have observed this behavior after carefully setting up our K3s for WSJT-X operation with the K144XV. KB7Q found if he ran JT65 in USB mode the power setting behavior of the K144XV was normal but if he ran in DATA

I have made the same observations with my K3/K144XV, vintage 2010: 8 Watts out at 0dBm in and 4 Watts out at –10dBm in, all power measurements done on calibrated Bird and Boonton meters. The transverter performs very well and gets clean signal reports, so it is not excessively non-linear. The

Re: [Elecraft] [K3] Fan Replacement

Thanks to Harry and John for the excellent advice on the replacement fan. The UTEC fans that came with my most recent KPA3 (September 2013) were very annoying to me since I have a quiet radio room with no amplifier. The problem was not so much one of volume as sound quality. The fan noise was buz

Ron et al, Compared to my XV50/K2 station my K3 is much more practical on 6 meters in a suburban, high noise, high EMI environment (metro Phoenix). The attenuator had to be always on in my K2 to keep it from being overloaded by the XV50 RX output. In addition I turned the K2 RF gain down to br

Yes, 200Hz, 500Hz and 2.7kHz filters in both receivers; I deal with extreme noise in my suburban location and find using the 200Hz filters helps enormously. Nothing special for receive antennas: a K9AY loop array and the N6RK remote tuned coaxial loop (www.n6rk.com ). I

Thanks Ed for pointing out the ambiguity: I meant the K2 mic connectors. The TTDXD interface connectors also carry headphone audio and keying signals to the tranceivers. 73 Gary, N7IR At 04:26 PM 2/2/05 -0500, you wrote: > > >gary: >Unplug which mike connectors - in K2 or ten ten dx doubler >Ed,
