Tom, There is no 'power supply of choice' that I am aware of except for MY choice! I don't like the noise potential of switching supplies (but I admit many are reported as no noise problem). I use a linear supply and keep it on the floor under the operating table. Transformers can couple into the K2 and cause a bit of hum on the transmitted signal if positioned close (keep them 2 feet or more away from the K2).
If you are considering battery power for your QRP K2 (either the internal KBT2 or an external gel cell), you might want to take some hints from the 'SmartCharger' article on my website www.qsl.net/w3fpr. I use the K2 internal battery and the SmartCharger on my QRP K2 and use an Astron RS-35A to power my separately mounted KPA100. Battery Powered K2 to go and 100 watts from the home QTH - just pick it up, disconnect 4 cables (KIO2, Antenna, Key, and SmartCharger lines) and it is ready to go portable. 73, Don W3FPR > -----Original Message----- > > I've been kinda lurking for a while and haven't seen much about power > supplies. > > Is there a 'supply of choice' for the K2?
