[Amps] Alpha 87A Won't Transmit

[Ian White GM3SEK]

Two tricks that help with soldering to conventional PL259 bodies:

1. File across each of the four solder holes using a 1/8in round file, 
reducing the thickness of metal to leave sharp edges of bare brass. The 
thin metal is much easier to heat up with a soldering iron.

2. To make even less work for the soldering iron, pre-heat the connector 
body to around 100C/200F usinga hot-air gun. (Take care not to blow hot 
air directly onto the cable jacket; if necessary, loosely wrap the 
exposed jacket with aluminum foil.)

With these methods, even a 40W soldering iron can give good joints every 
time.
