Re: [Elecraft] KCOMM for K3

For what it's worth, I downloaded it, changed the code to accept dates up to 2050, and compiled it in Lazarus successfully under Windows 10. But it didn't run -- runtime exception. I'll have to look into it further. Incidentally, the date validation function is in utils.pas, not main.pas. 73,

Re: [Elecraft] A or B?

It's a version of mode b with slightly different timing. It is easier to send with fewer mistakes than the usual mode b. I got addicted to it and had a hard time when I changed to the mode b in the WinKey. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

There is only a difference if you squeeze the paddles, to make a C for example. Try sending C's with one squeeze in mode A and B and you will feel the difference. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO https://www.qsl.net/k2vco/ On 06/07/2021 20:49, jerry wrote: All,   I

[Elecraft] OT: Nano VNA

Only marginally Elecraft related, but I want to buy a Nano VNA. There are numerous models and sources. (for example, Amazon has a bunch of them ). They are also all over eBay, Ali Express, etc. I don't want to mess this up. What model should I

Re: [Elecraft] Gurus

I live in a place where there is a ham with a legal limit rig and a big beam less than 1 km. away. Antennas are line of sight. His signal renders about 10-20 kHz of the (CW) band unusable, with lesser effects extending out farther. He does not have clicks; it is phase noise (or something

Re: [Elecraft] best grounding technique

Having a bus that runs the length of an operating desk with all the equipment connected to it by short straps is not that different from bonding each piece of equipment to the ones next to it. But it allows you to remove one unit without breaking the "chain." This is contrasted to the "star"

Michael, The low power K2 does not have an amplifier keying output. It is easy to create one, using the 8R line to operate a transistor switch. Such a circuit is shown here and there are others. However, most are

Re: [Elecraft] K3 synth / PLL faulty

The first thing to do when anything seems weird about the synths is to check all of those little cables. Make they are all well-seated, and push the connectors in and out a few times to clean off any corrosion. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO

I brought all the connections to the relays the KRC2 operates and its power supply in via a piece of multiconductor cable, wrapped 10 turns of it around a #31 toroid and I have since had no problems with 1200 watts to an antenna about 4m above my roof. No special treatment was need for the

Re: [Elecraft] [K3] Locking VFO B

t’s either a bug or a feature.  When in diversity mode and BSET using LOCK gives the same response as RX ANT.  Maybe what it’s trying to say is that you can’t lock B because it is already “locked” to VFO A . Ken K6MR *From: *Victor Rosenthal 4X6GP <mailto:k2vco@gmail.com> *Sent: *Sun
