I was using ETA 106-P30 trips that have internal resistance of 0.9ohm for
the 1a and 0.05 for the 5 amp. The problem was my Becker radio which only
likes to work at 12V+. The 5amp breaker dropped the voltage by over 1V on
transmit which for SLA batteries made it unworkable. A standard blade fuse
had much less impact.

Unless your Becker is about 25+ years old, there is something wrong with
it. For decades, Beckers have worked to 10 volts.
