[R-390] Silver solder

[Jim Brannigan]

The only time I used Silver Solder in a radio was to connect a BNC to a
circuit board in an HT.
Flexing of the antenna kept breaking the tin/lead connection, silver fixed
it.
With a good mechanical connection the strength of silver is
unnecessary.....and the additional heat to solder it undesirable.
