[UK-CONTEST] Alinco switched-mode power supply from RSGB

[Stewart Rolfe]

Hi all,

The enjoyment of my new K3 was being severely compromised by an old 
linear power supply whose fan sounded like an old vacuum cleaner and 
whose transformer buzzed loudly in time with my cw at any powers above 
about 20 watts.

So I decided to take a chance on a switcher and bought the Alinco 
DM-330MW on offer at the moment in RadCom for 79.95ukp (RSGB members) 
until the end of February. What a difference.....the silence is 
deafening! I can now hear the K3's dulcet sidetone and a quick flick 
across the bands has not shown up any obvious switching noise either.

It's small size and weight makes it an ideal companion to the K3 and the 
duo would make a great combo for a field day or dxpedition. I'll reserve 
final judgement until I've used it a couple of weeks and had a good 
check for digital nasties but it looks very good so far.....

73,

PS - Anyone want to buy a Watson W-30AM power supply with built in 
sidetone....?
