Q:3.1.1 What power supply should I use with the IC-746?
Short Answer
Any good quality, communications grade, power supply
rated at least 20 amps or more (continuous duty) should
do just fine. However, most of us use larger supplies
(for a variety of reasons).
Popular supplies that are known to work (via testimonial):
Alinco DM-330MVT 30/32A switching
Astron RS-35M 25/35A linear
Astron SS-30 25/30A switching
Astron SS-25 20/25A switching
MFJ 4125 22/25A switching (MightyLite)
MFJ 4225 22/25A switching
MFJ 4035-MV 30/35A linear
Samlex SEC-1223 23/25A switching
Kenwood PS-52 20/22A linear
Power supplies to avoid (via testimonial):
Astron RS-20 - overloads too easily
Kenwood PS-30 - overloads too easily
Diamnond GZV-4000 - RF hash on 40/20m
Icom PS-85 - RF hash
Long Answer
This question typically arises for one of two reasons.
Either someone wants to buy a new power supply, or they
have an existing power supply that they want to use.
In both cases, the issues are: load capacity, size,
weight, electrical noise, mechanical noise, cost,
features, and appearance. Buying a new supply gives
you a lot of options; there are plenty of great supplies
out there. With an existing supply, you have no control
over these factors; you're simply looking for a "fit".
You'll want to consider the following factors.
