Steven Simons All Messages By This Member #971 开云体育 Andrew, Good morning – I am finally getting back to my FT-847 troubleshooting. ? Yesterday, I performed the test of TP1003 and adjustment of T1009. ? I found that there is a maximum voltage of 0.572 which varies by adjusting T1009. Note that this voltage is present in RX or in TX (CW) – it just remains steady. ? So, what is the next step ? ? Thanks and 73, Steve ? W1SMS Steven M.

I do have a copy of the service manual - which I plan on reviewing prior to performing any adjustments. I'll probe the test points you refer to and see what I find. "stay tuned".... de: W1SMS
