[Elecraft] Removing/connecting PL-259s

[K9MA]

I use a single PL-259 for all the transmitting antennas as a lightning 
disconnect. I can attest to the fact that trouble ensues if I forget to 
tighten it with the pliers. I crashed my computer during the contest 
today. Twice, before I caught on.

73,
