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. Dual CPUs for system operation, monitoring and control. Extra ferrite rings installed for RFI prevention. A few marks on the case. Keep mine in a 19 rack and I don't seem them. Antenna tuning unit (ATU) does not work. I bought it like this and have used it with resonant antennas with great success. It works very well, I've used resonant antennas, multi band verticals very effectively.
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 12W 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 1W, transmit carrier to check reflected power (VSWR). 3 assuming VSWR ok, set output to 12W for UK legal limit.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.

Contact me first before relying on this, as transport is not my day job.
