Isn't 4. mm = 0.1575 inch? If so, 4 mm is within the quoted WWII spec size
range. The problem would not be specifying 4 mm but
I am using the Times Microwave connectors on Times Microwave LMR-400 for my HF
antennas. Except a Belsen 8267 jumper around the rotor to Yagi. The Times
Mocrowave connectors for RG8, 214, 214, 9913, and LMR400. I had the LMR400 left
over from a job so no cost except the UJF male and one UHF

5/32” inches is 0.156” which is 3.968 mm. So if the Asian manufacturer
considers 4 mm easier and close enough the pin will be oversize.WW II
drawings give the pin diameter as max/min 0.158/0.154 . 5/32 is right in the
middle of this range. I don’t have the MILSPEC documentation but guess
Probably! Belden cable with Amphenol connectors ...

For several decades, I've served on the Standards Committee of the Audio
Engineering Society with
"The secondary toroid of the directional coupler has a direct path to ground.
That means there is no straight-through DC path."
I may have misunderstood the schematics. What I see is a DC path between J1
input and "ATU". If K20, K21 and K18 are all in the NC state there will be a

Andy, my friend, you are forgetting something. The secondary toroid of the
directional coupler has a direct path to ground. That means there is no
straight-through DC path.
Rare that I catch Andy on something…

KAT500 antenna selection drops to ANT-1 when there is no power on KAT500.
Also, with no power on KAT500, the Bypass relay defaults to bypass state.
There should be a simple DC path between input RF connector and ANT-1 RF
connector if the KAT500 is not powered.
Pull the DC input plug and the

All,
This is likely something very straight forward, but I do not have a
schematic to follow and troubleshoot.
Symptom: ANT 1 circuit seems to be dead. No match and fault on switch from
ANT2 to ANT1. No receive signal.
Tests:
Took KAT500 out of line to by-pass tuner, antenna on ANT1 is OK
