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.
