[Elecraft] recommended switching supply

[Don Brown]

Hi

I have 3 MFJ power supplies and an Astron SS25M. They all work great with the K2/100 or any other radio I have used with them. I use a MFJ 4225MV on my work bench to power radios that I am working on or aligning. I use a MFJ 4245MV in my shack powering a K2/100 with 3 transverters and a Kenwood TR-D700 VHF/UHF FM radio. I use a MFJ 4125 and/or the SS25M for portable work like field day when I am not using solar power. I have never had any problem with hash on any of these supplies. I like the MFJ 42xx supplies because of the lighted meters, front panel voltage adjustment and cigar lighter socket on the front panel for easy connecting of accessories or a HT in addition to the normal 5 way banana sockets. The MFJ 4125 does not have any meters and has an internal voltage adjustment but it is the smallest lightest and quietest of them all. It has a 25 amp output on the front panel and a 5 amp connector on the rear for accessories. The astron has meters although not lighted and the voltage adjust is internal. All of the supplies have over current shut down. I have adapted the output of these power supplies to PowerPole connectors so I can plug in a RigRunner 405 or 408

  I want to purchase a switching supply for use with my K2/100. I used a small Astron SS (7amp) before I upgraded with the 100 watt amplifier. I never had any noise problems with the Astron. 

  I have heard a lot of favorable recommendations on others but would appreciate any comments (negative or positive . . . . no pun intended) about the various ones that are available. 

  The MFJ and Alinco look nice too me. MFJ always seems to have a stigma about their products. I see they advertise that they (MFJ) do not have any hash problems in the ham bands.

  TIA
