Somebody mentioned the reliability of military connectors. One well-known
military connector (Pattern 105 series) used in millions has a 500 insertions
limit. Reliability is calculated from a change of resistance beyond a given
limit at a given current, ambient temperature, etc. Most
I have the same desires.

I prefer the FT1000MP sound to the Pro3. It's more like my Drake TR7: a softer
(shall I say) analogue sound. I get quickly fatigued with the Pro3 which I
find harsh, rasping; though I do hear weaker stations, ie better for dx seeking
than contesting. Looking forward to putting the K3 in an
I think the point about grounding unused antennas is most probably to drain
static in which case a resistor in the grounding line would work and not detune
much.
I wonder if anybody uses chokes on their verticals as they do on broadcast
stations.

I found the FT1000MP to have a softer, more pleasant sound and easier to do
long operating times compared to the 756 which was unpleasant after just a few
minutes, even tho it seemed to perform better.
