Awesome!!!!  Time owned: 0 to 3 months
Wow! I've tried many 2 meter amplifiers in the past ten years in the hobby and Jim's new one kilowatt is by far one of the nicest I've owned. So many features to list here:
- Compact cabinet design (6.5 x 12 x 12 inches)
- Full VSWR and over-temperature protection
- Metering for PA voltage & current, with
- Peak-reading LED bar graph meters for forward and reflected power.
- Full t/r sequencing
- Low-loss high-power antenna relays
- ALC output for the driver
- Low-noise temperature-controlled cooling fans
- Front-panel AC switch for it's external power supply

I hooked a HP Blade type 50 volt power supply to this amplifier. I flip the switch on and it take about 3-5 seconds for the power supply to boot and come up to voltage then I'm ready to roll. The amp is quiet and the ALC soft start circuit is amazing. Gradually brings the amp from zero to over a kilowatt in under a second. Blocks the radio output until all relays have closed and LNA out of line, then brings power up. This amp loafs along at the 1 kilowatt power range. Very Nice build by Jim!!
