[Amps] Alpha 87A Won't Transmit

[Tim Duffy]

Hello Ron:

There are 100's of PL-259's here at K3LR soldered that way - and they work perfect. No failures in over 40 years of doing this method shown to me by N4AR.
Best of all the dielectric never melts when soldering the shield. 

I have seen other stations where guys try to solder through the body holes with terrible results. If you can do it - that is great.

   This method is the wrong method.  As recommend by the ARRL and others,
It is best to not fan out the shield, but cut it about ¼" past the 
jacket and tin
the shield  into copper tube, then screw the connector on to the cable, 
threaded
onto the jacket and solder through the FOUR holes from the connector to the
tinned shield.  A pencil tip flame propane torch can be used, if very 
careful use
is involved.

   When I began as a broadcast engineer in 1963 every video cable had a
PL259 on each end of sections of RG-11/U and dependability was job #1.
                                                               75Ω
