Re: [Elecraft] (OT) - Unplanned Discovery

I have often wondered if the noise from a switching power supply would vary in intensity or other characteristics as the load changes. For example, during transmitting. In a single transmitter environment the user would probably not notice but in a multi-transmitter or SO2R station one just

Re: [Elecraft] O.T. Morse is not dead, at least in the U.S. Navy

Yes, it is morse code although the protocol is very different. For example, to call a distant (unknown) ship you point your big light at them and send AA. The proper response is a lng T. There’s a book carried aboard all ships that documents the protocols. I have a copy here

Re: [Elecraft] Mobile antenna breakthrough?

Yes, I was thinking along the same lines — that copper ‘conductive tape’ stuff. It could be mounted to the outside of the carrier and would look like stylish racing stripes! http://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Conductive-Copper-Foil-Tape-3313?N=5002385+3293242553=rud

Re: [Elecraft] OT Learning Morse anew

I was one of the last Radio Officers to sail an all CW ship. It was the SS Tampa Bay, call sign KNJA. We worked our way up and down the South American coasts from ports in the US gulf coast. I mainly worked WLO on 16 and 22 MHz. We typically hummed along around 30 WPM due to the requirement

Re: [Elecraft] OT Learning Morse anew

I agree about getting on the air. And, about the value of the old Novice class in providing a “safe harbor”. When I got my novice ticket I went out and bought crystals for various frequencies on 80, 40 and 15 meters. Frequencies were random and I had three on 80 meters — 3713, 3723 and 3741.

Re: [Elecraft] OT - operating QRP at same park

Re: [Elecraft] Amplifier thoughts

I cast my ballot for NO internal coupler. 1) An internal coupler is NOT needed by many who would rather not pay for something they don’t need. Sure, it could be optional but see points 2 and 3. 2) An internal coupler at 1.5 KW as anything beyond a trivial “line flattener” will be large. If

Yup. Earlier in the thread Mike / KK5F pointed that out. He was on the RX end of the circuit. We monitored stations from Perth, somewhere in the UK, east coast of USA, west coast of USA, etc. etc. Must have been six or eight stations on the air. We also monitored WWVB but I think that was

Re: [Elecraft] K3S ELF 10KHz

Way back in ancient times I worked at a research lab where we had a LOT of receivers tuned to all the signals we could find below 60 kHz. I think the lowest was 13.x. There was an 18.x and 24.x etc. etc. We were only interested in signal strengths and plotted each signal on strip chart

Re: [Elecraft] winkeyer

Yup, I am using a WinKeyer USB with a K3S and ACOM 1500. The WinKeyer is driven by N1MM+ and by paddles. I run the K3S in QSK mode. The K3S controls the amp key line. Works great; no problems whatsoever. Do you have specific questions? 73, Doug, W7KF http://www.w7kf.com

[Elecraft] K3S Chirp?

I was in the CW SS in November using my then new K3S with an ACOM 1500. All of which was *great*. But, then, I received an Official Observer Advisory Notice that I was “emitting a CW signal with a chirp”. The report detailed a QSO that is, indeed, in my SS log. I was running on 20 meters

Re: [Elecraft] K-Pods and Contests

Re: [Elecraft] Would a matching speaker be nice??

How about a speaker cabinet with mounting holes such that a commonly available power supply could be mounted inside? With a slot on the back panel for the incoming and outgoing power leads? All it would take would be a loose alliance with a power supply company like Samlex for example.

Re: [Elecraft] [OT] A Real SOS

In the old days there were some pretty creaky old timers out there. But, the newer SOLAS requirements pretty much put an end to that. Now, anyone working on a ship has to have gone through a couple of days of survival swimming, a couple of days of ship-board fire fighting training, etc. etc.
