Re: [Elecraft] ptt-key

2024-04-04 Thread W3FPR 

Evert,

I am recalling that this is intentional to keep the K3/K3S from being 
keyed when the computer is powered up after the K3.  IIRC the mechanism 
is reversed after some action at the computer port. Do a search through 
the Firmware archives for mention of PTT-KEY to find the answer.

Can this be stored permanent or am I missing something?

Timing is everything!  The Earth-facing half of the sun is currently 
extremely quiet, SFI is around 112, down from nearly 200.  The sun 
rotates in roughly 28 days [various latitudes do so at somewhat 
different rates] so try again in about 14-20 days.

20 years ago, or thereabouts, when I lived in Northern VA I was a pretty
regular checkin on the Elecraft CW Net with my little KX-1. Amazingly, it
did quite well.

Over the Easter weekend I was once again in NOVA (visiting at my son's
house) and, ever the eternal optimist, I decided to see what I could hear
with my KX-3 and the AX-1 whip (yeah I know, dream on).

Hear K4JPN rock solid. Faint noises from others and the timing suggests
that some of what I heard was most likely Kevin but I couldn't decode
anything.

No surprise, right?  Just thought I'd mention it anyway.   Maybe some day.
