7 mhz and the 6 meter band. I used it with a flex 1500 Sadr transceiver but this would work fine with any qrp to give you a little boost when conditions require a little more horsepower. 50 watt output amplifier covers Somewhat uncommon amplifier.
Included are the amplifier, original box and instruction manual and short power cable. Plenty of positive information on the internet regarding this amplifier. Works perfectly.
Excellent condition Tokyo hy power hl 50b.
