[Elecraft] New CW audio recording: K3 vs. K4D

[Elecraft] KPA1500 Ethernet port RFI, cause and cure

*Summary*: To avoid 20m narrow band RFI generated by the KPA1500 and other Ethernet devices, use shielded Ethernet cables, CAT5 STP or CAT6 STP, instead of CAT5e UTP or CAT6 UTP. *Details*: The KPA1500 and some SDRs provide a 100 Mbps Ethernet port, which may be tempting to use instead of USB

Re: [Elecraft] P3: Left span limit changes

Having the P3 remember the last-used span *and center frequency* on each band across power cycles when the P3 is in Fixed mode will be a big improvement, even if the P3 ignores the operating mode. The K3 remembers the last-used frequency and mode on each band, so the two devices will (more or

Re: [Elecraft] TX DLY distortion

If you are using the internal keyer of the K3 (or KY commands), with CW QRQ OFF, there is no timing distortion of transmitted CW elements for any value of CONFIG:TX DLY, as long as VOX is used, and the PTT line is not closed with a footswitch. The internal keyer compensates for the increased TX

Re: [Elecraft] Transmit Inhibit

What amp. are you using and why do you need to use TX INH? Perhaps it has KEY IN / KEY OUT, and you can use that instead, to activate PTT on the radio only when the amp. is "ready". PTT signal or footswitch keys amp., amp. keys K3 PTT IN, instead of PTT/footswitch keying radio, and radio keying

Re: [Elecraft] Strange power problem with KPA1500

Sounds like an ALC issue. Do you have CONFIG:EXT ALC OFF? Also, do you have CONFIG:TUN PWR set to NOR or to a fixed low level? Instead of switching to CW, what happens if you press OPER on the AMP, then press (hold) the TUNE button on the K3? Then immediately try the mic? Try setting

Re: [Elecraft] K3 Strange Power Output Problem

I can't replicate this problem with the KBPF3 installed in the Sub Rx instead of the main. CONFIG:KBPF3 says "Not Inst", for main, "Sub Nor" when I tap SUB. If you have the KRX3 Sub Receiver installed, a possible workaround is to operate with SPLIT *OFF*, SUB ON. Now you're transmitting on A,

Re: [Elecraft] KPA500/K3 AUX bus specification

Bill, The Y-BOX v2.1 and single $20 25ft M/F "HD15" cable could let you remote the KPA1500 or KPA500 to the garage quite nicely, including remote power power on/off via a K3 macro. I haven't tested a cable that long, but know of no reason that it won't work as long as the voltage drop isn't

Re: [Elecraft] P3 Waterfall

I recently saw this happen on W6NV's P3 after upgrading the firmware from a very old version to the most recent version in one jump, or perhaps I accidentally removed power from the back of the P3 while it was on, while simultaneously bumping one of the front panel buttons. Reloading the firmware
