ICOM IC-PW1 Linear Amplifier 1KW, 1000W

  

ICOM PW1 Kilowatt-class linear amplifier. No need to mess about with plate and load settings like valve-based linears. Rated for 1000W output at 50ohms. 100% duty cycle (even during RTTY or SSTV). Automatic AC input voltage selector. I manually select the band and keep an eye on the output. 25W SSB PEP gives about 1000W into a dummy load... I set my radio to 10W for a nice 400W ish. The reviews say this amplifier can output 1.4KW with 35W in, but for longevity (and your license) I recommend that you stick with 400-500W (the extra to account for feeder loss). This linear loafs along at UK's power limit.

10-15W is perfect for an Elecraft KX2, KX3 etc. This amplifier is for experienced operators only.

It will stress your feeder, chokes, baluns and antennas if they are not up to scratch. You can hurt yourself or others if you don't know what you're doing. This is the procedure I use. 1 set linear to whatever band you want to operate on. 2 set exciter power output to 2W, transmit carrier to check reflected power (VSWR). 3 assuming VSWR ok, set output to 10-15W for UK legal limit (band dependent). Maximum recommended power between 22-28W input for just over 1KW, band dependent. Step 2 is optional, but good practice. ATU does not work automatically or manually, it is quite a common problem, google will expand on this for you. Note this item is advertised elsewhere, so may be withdrawn without notice. Collect from KT17 3LB - full social distancing protocols to be observed please. NI, not sure how the new rules work, but I'll work with you. Unit will be security marked.
