Well, my Diamond X300A reaches out there, but only if the radio is working. Intermittently, the IC-706MKIIG fails to transmit on 2m or 70cm. The power output meter bounces momentarily to full power then back down to about 20-30%. It looks like the sort of thing the rig will do into a bad load, but I can verify with two other rigs (Icom ID-51 and Kenwood TM-731A) that the antenna is good.<\/p>\n
On a mods webpage, there is mention of a fix for a problem specifically with FM transmit that is very similar to what I am experiencing. The fix is basically reflowing the solder on an adjustable capacitor. The next time the symptom shows, I will try to remember to look at FM on HF to see if it happens there as well as SSB on 2m or 70cm.<\/p>\n
My gut feeling has been that its something in the power amp to antenna connection chain. Once I have the box open, I will look at both.<\/p>\n","protected":false},"excerpt":{"rendered":"
