My dad (G3PJW) became a silent key about a month ago and I am now trying to sort out his radio legacy - some of which goes back almost 50 years! However, on his shelf was a more recent Icom-T81E. I have sort of charged the rig - the voltage on switch-on was showing 5v and after charge it was up to 7v. I’ve discharged and re-charged the rig a couple of times now but when pressing the ptt the rig initially transmits and then closes down after about 1 second. Receive is fine and both transmit and receive are fine when using an external dc supply. I’ve only been able to charge the rig by applying the external dc supply.
I’ve read the manual and this behaviour suggests that the battery pack may need replacing, although the manual suggests doing several charges and discharges if the rig hasn’t been used for a while (like this one). What I would like to know is if in fact this is the likely situation. Up until testing some of dad’s other gear this week, I have never operated VHF/UHF FM so please forgive my naivety (I did manage to listen to M1EYP/M through GB3MN last night though!). In the meantime I will continue with the charging/discharging cycle to see if the battery pack comes back to life.
