[Elecraft] K3 RX / Aux Issue with TX

I have K3 #512, with 2nd rcvr. I have the latest release firmware. I have the aux antenna and rx antennas jacks connected together, and fed by switchable receive antennas. My transmit antenna is approximately 120' away, and perpendicular to, the closest receive antenna. While transmitting

[Elecraft] RJ-11 connector on bottom of the Front Panel

What signals are available on the RJ-11 connector on the bottom of the front panel? I see some lines on the schematic that indicate the data bus is available. Can the signals on the RJ-11 be controlled via macros, or can I cause a front-panel button to put something on those control lines

Re: [Elecraft] K3 receiver desensing on CW during contest

I believe that I encountered this a couple of times while in VP5 last fall... there wasn't a roar of stations, the radio just sort of sat there and 'hummed'. I turned the radio off, then back on, rechecked all of the settings, and kept going. Brian N9ADG --- On Sun, 2/22/09, Merv Schweigert

Re: [Elecraft] KPA-800 any news at Dayton?

Speculation: Elecraft does great 'smart' things. How about an amp that takes advantage of a CW-preferring user base; tightly integrated with the K3; takes it to the next level: Class E amp, initially supporting only CW, but over time and with some firmware upgrades, and with all of the DSP

IF you have the USB/Serial adapter, try unplugging that from the K3 AND the computer -- it's powered by the computer. The first one that came with the K3 was S9 in the 160m band; replacing the USB/serial adapter cured it. W6NEK [EMAIL PROTECTED] wrote: Hi OM, Do you hear the signal with a

We used two K3s for a M/2 in last weeks's contest, and did over 2000 Q's; I second the N1MM / FSK recommendation, as there are few variables to manage if I don't have to worry about TX levels. Also, it's definitely an opinion, but on the receive side, I personally dislike seeing other ops
