This rig was purchased as surplus, and converted to amateur radio frequencies according to the mods of LA9AHA. It is a part of my packet radio setup. For any-one interested mail me at LA9IHA@LA3F.
The rig is very solid and reliable. I have reduced the output power to minimum. At higher duty-cycle it will get very hot. This is apperently normal. I use the rig at 24/7 operation.
