|Customer Reviews for the MFJ-403.|
|From: Doc WB0FDJ|
|I bought this keyer to use with all of my QRP rigs. SWL 20 and 40, Cubs, HW-8, Tuna Tins, whatever. I know it looks like something Rube Goldberg might have come up with with the clunky looking paddle on top but, hey, it works and works well. It provides a sidetone for rigs that don't have one. The "on-the-fly" adjustable speed is very handy (easier that going into a menu while operating). Once I got used to the funny looking paddles I find they work very well. Runs forever on the 9 V battery. If I feel really frisky I will plug in my Vibroplex paddles. Yeah, I like it and have not had a problem. As I write this it's plugged into my newly built AC-1 Junior. Well worth the cost. |MFJ-4230MVCOMPACT SWITCH PS, METER, 4-16V ADJ. 110/220VACOnly $89.95! MFJ-4125SWITCHING POWER SUPPLY, BASIC, 25 AMPSOnly $84.95!
