There's no question that there's lots of competition for not a lot of available business, and the board fabricators are scrambling for position. One time was that standard "no rush charge" lead time

Actually, in my experience with repeaters, 375W output on 146 MHz will definitely make RG213/U warm, and can make 9913 warm as well. That power level will literally "melt" RG8X (mini-8). Of course, a

To be legit, you'll only pick up 3dB, so not sure if this is going to be exactly the pileup buster you had hoped. Actually, the 1000MP runs >100W output, anyway, especially on CW where you don't have

The reason most 220V appliances including amplifiers sold in the U.S. do not come with an attached plug is that there is no standard for these plugs and their mating outlets. A "dryer plug" is normal
