Re: [Elecraft] K3 / K3S Power Supply

Astron RS70M here and it's still going strong after 30 years. Definitely overkill for my downsized, condo QTH, but it sits under a desk, out of the way, and I have strong floor joists :-) Barry w2UP -- View this message in context:

Re: [Elecraft] K2/KPA "Low Batt" warning and beep

11.5 volts is where you should start seeing LO BATT on the K2 display. I don't recall a audible tone, but it's possible. The K2 alone is spec'd down to 9.5 VDC supply, but at reduced output as follows: 9.0 V min for 2 watts out 9.5 V min for 5 watts out 10.0 V min for 7 watts out 10.5 V min for

Re: [Elecraft] (K3) need help with cw keying - right now

Bingo! The line from the key terminates in a 1/8" jack. The adapter from their to the 1/4" K3 jack was somehow bad. No short in the jack or in the key line separately. But, when connected together, there was the short between the tip and the ring. Damnedest thing. Thanks, Bill. Now on to the

Re: [Elecraft] P3 Showing Transmit Signal

I finished the SSCW on 40 and while in QSK noticed my own echoes. I thought that the K3's QSK or sidetone had weirded out and was confused and bummed out about it until I listened on a 2nd receiver and figured out that it was my own echoes, although I didn't believe what I was hearing. I've

Re: [Elecraft] Long Path Echoes

Jim, I have had the same results into the Ukraine and Europe in the mornings before sunrise here at my Amador county QTH with my 160 Meter double extended Zepps that have a 80 meter lobe right at them.  The path did not last long and was very selective on stations worked, area wise. Mel, K6KBE

[Elecraft] LDEs (Long-Delayed Echos)

I just finished reading Eric Nichol’s (KL7AJ) book titled Radio Science for the Radio Amateur, in which LDEs and other non-linear propagation events are discussed (ch. 11). Eric considers some of the proposed explanations but concludes that none of them really work. I heard it myself once on

[Elecraft] Can an oscilloscope be made to do spectrum analysis?

I just purchased a DS1102E Rigol Œscope and wondered if those who use this or similar equipment have been able to use it as a spectrum analyzer (to draw amplitude vs frequency rather than amplitude vs time.) The Rigol has an external trigger channel, which if I remember correctly from the last

A short in the keying path - most likely external to the K3. At the key, inside the plug? Just a shot in the dark. Bill W2BLC K-Line __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

[Elecraft] [KX3] Can someone help explain this - AM/LSB/CW Freq

I was playing around with an RigExperts AA-54 antenna analyzer today using it as a signal source for the KX3. I fed the AA-54 into a Alex Loop inside the house and had the KX3 connected to my mini-G5RV outside. I set the AA-54 to do continuous spot measurements at approx 14.082MHz. In this

[Elecraft] K2/KPA "Low Batt" warning and beep

I'm checking my K2/KPA rig as the battery runs down. I'm getting a sporadic "low Batt" indication on the screen and a beep every once and a while during transmit. The supply voltage under load is still about 11.5 V. Is this coming from the K2 or the KPA? Is the level at which this warning

All of a sudden and for whatever reason, when using my Vibroplex hand key [3-pins], all I can get is an automatic "A" that keeps repeating, in either paddle direction. Need help if I'm going to do anything in the contest! Thanks. ...robert -- Robert G Strickland, PhD ABPH - KE2WY
