Great product  Time owned: 6 to 12 months
Totally happy with this amp. Works exactly as advertised. I have it paired with my ELAD FDM-DUO qrp transceiver. With the ELAD set to max power, the amp will put out about 225W on 40 and 20m, about 200W on 17m and somewhere between 150 and 175W on 15, 12 and 10m. Automatic band switching works perfectly with the ELAD radio.

Good amp, I'm happy.   Time owned: 6 to 12 months
This IS FCC type accepted.
I purchased this to provide a little muscle for my FDM-Duo sdr transceiver. It will require a beefy 12 volt power supply, at full keydown it will draw about 30 amps. 4 watts in will give 250 watts output. I would advise using a muffin fan if you dont buy the model that comes equipped with them. The auto band switching is seamless. Works great.
The only con I have is : Your antenna SWR should be well 1.5:1 or better. The high SWR protection on this is not too forgiving. I use it with an MFJ-998 auto-tuner and when changing bands I have to "pre-key" the tuner with another rig to make sure my swr is within range or I will have to reboot the amp. Thats more of an issue with the tuner... It will not tune with less than 10 watts input.
