A pound to a pinch of salt it's a poor connector.

On a related tack, I am often surprised at how high the radio volume has
become in the club shack. On turning it down, it is quite a relief on the
ears and yet perception of the signal we are listening to improves. It is
also significant that a separate loudspeaker on a shelf being more in line
Thanks, Paul. My question was naive in only asking for speed. Several have
pointed out that latency is probably more important because the speed is
easy to attain. I need to translate this to the characteristics that the
providers use, eg ping, which I know little about. From advice I have
I will soon be building a remote control station about 20miles away. Both
stations have access to broadband, but what speed will give satisfactory
results?
tnx and 73

Am I correct in thinking that the P3 is the only way to obtain a *remote*
panadapter with the K3S? ie this cannot be done with some other sdr
combination as has been suggested for home operation?

Is it radio? The Heyphone relied on magnetic coupling between a loop
underground and another on the surface. At the time the distance was in
the 100 to 200m range, ie too short to form an electromagnetic wave,
therefore not radio. It's an interesting subject.

I liaised with John around 25 years ago to set up what we thought would be a
unique event: communicating from underground in Stump Cross Caverns North
Yorkshire, to an HF station on ground, then to the world. We had a couple
dozen scouts and members of my club helping at the event for JOTA. We
I teach modern jive which is now far more popular than ballroom dancing
which I trained in in my 20's. Now in my 70's this has a very healthy
following and is far easier to learn without private lessons. I met both my
XYLs (40 years apart) at dance venues. Mostly popular with >40 year-olds.
Glad you raised that, Ted. It reminds me of another application in which I
wanted a slower rise and fall time for an inductive load. My solution was to
add a small capacitor between base and collector
of the drive transistor which also meant I did not need the protective.

I worked from southern Spain back to GD with a KX1 running 4W from a pocket
battery pack using a 9m fishing pole and an "offset Y" 20m dipole made from
tv twin right into the banana splitter. For trekking long distances I would
go for a much smaller and lighter weight pole and an easier aerial
