Re: [Elecraft] [K3] Issue with HI CUR on 12m

Bill, I would suggest that you check the SWR on the antenna before concluding it is an RF feedback problem. Don't forget that the balun may be breaking down with power and show no problem at lower power (like from an antenna analyzer). Don W3FPR On 10/11/2020 8:53 PM, Bill Coleman wrote: Do

[Elecraft] Elecraft CW Net Report

Good Evening,    QSB made life interesting.  It varied from slow waves running from S3 to S9 followed by faster rates as I copied farther west. By the time I landed in CO or TX the rate began chopping characters.  I had to ask W0LI for many repetitions.  Each element was being broken into dits

If this has already been announced here, forgive me; when life is busy as it has been over the last couple of weeks I don't always read the reflector. In any case the news is worth repeating. In the October issue of QST, at p. 62, the ARRL announced that Jim Brown, K9YC, a frequent contributor

Don, I finally got around to running my K3 into a dummy load. I had no problem running 100w or even 110w with a dummy load. Current draw from the power supply was 22 A and 23 A, respectively, on the K3 display. No HI CUR indications. External wattmeter validates the output. I was getting the

[Elecraft] [K4] Three RX antennas?

2020-10-11 Thread Jim Miller
I have an application where I would use 3 RX antennas. Two could use the RX1 and RX2 ports but the third would use one of the ports provided by the KAT4. My concern is avoiding accidentally transmitting thru that third RX port. Will the ANT CFG constraint of the TX antenna to ANT1 ensure that? 73
