On Ken Kopp, K0PP's advice (nice call by the way), I checked for some
markings. With bright light and a magnifier I find it's an Andrew 42W
connector, of which there is little info on the internet. Except that
it's for use with hardline, 1/2" I believe.
But with some more poking around on the
Not sure you have anything to do the measurement, but the center pin of a 50
ohm type n male connector should be 0.0640 inches in diameter (this is the
last part of the pin before it tapers to a blunted point). A 75 ohm pin
will be 0.0353 inches. It's easy to tell if you have one of each, but

Am I guessing correctly that a similar arrangement would work with the

Yes. Actually better, since the KAT2 has a wider matching range than
the KXAT1.

Jim's correct - There ARE differences between 75 and 50 ohm coax
connectors ... especially Type N.

Not so. There is a very real physical difference between 50-ohm and 75-ohm
type N connectors. The 50-ohm male pins are bigger than the 75-ohm pins and
will damage a 75-ohm female connector. Likewise if a 75-ohm male is mated
with a 50-ohm female there will not be good electrical contact.

The impedance is a characteristic of the coax cable, not the connector.
What does matter is what coax cable(s) the N connectors are designed
for, such as RG8, RG58, RG214, etc. Take a look at

I just picked up some fine looking heavily built male N connectors at a

Hi gang,
The K2 is the first rig I've had that has adjustable AGC. Under what
conditions would one benefit from using fast AGC? It seems that slow AGC is
easier on the ears on CW.
Thanks & 73,

Chuck,
Yes, the problem you are having is most likely related to the operation of
Control Board Q1 (or Q2). These are not a switching power supply, but they
do serve as switches to direct the 8 volts depending on whether the K2 is
trying to transmit of receive. Q1 and Q2 are not likely your prob
Yup, that was me. I used #26 enamel wire to form a complete loop around the
ceiling molding. The best configuration was with the loop shorted and a
single wire running down the corner of the room to the radio. You'll also
need a ground counterpoise wire -- I used about 16' of wire laid around
The filter has been sold pending payment.

I need to make or purchase an alternator line filter for my Ford F-150

While directly attaching a counter without a 10X probe can pull the

The fact that the relays did not cycle to reset with the control board
