Update: Icom IC-7000 Low UHF Output Power
Hi,
Months ago, I posted here regarding an Icom IC-7000 transceiver with low output power on UHF (440MHZ). I replaced Q401 (PA), RD60HUF1, a MOSFET device, and that fixed the problem. Now I have full output power when I transmit on the 440MHZ band. Note: I ordered it from "RF Parts". John N3AOF |

Well, I guess it was semi functional on UHF during that time, so there was no urgency.

RF Parts has been my staple supplier for 20+ years. The 7000 is a nice radio, improvements over the 706, all band DSP IF among many others. Better display too. -- Live Fast Die Young, Leave A Pretty Corpse |
