Thanks! My older USA Yaesu 857D (serial number 5H440xxx) had only these jumpers: 2, 1. I don't know how old it is, I bought it used a couple of years ago.
I want the Mars/Cap & full HF mod, so it will Rx & Tx on these freq: 1.8-56MHz, 137-164MHz, 420-470MHz
Removed jumpers 1 & 2. Added jumpers 9,8,7. Reset by holding in Func & V/M while powering on. Many memory locations would not accept input from CHIRP, couldn’t use them. Added a jumper on 6, and reset again. Now fixed. Tested by transmitting on 467.650 which worked great now, and did not Tx before mod (before mod radio display said: Tx Error).
When using CHIRP to reload memories after mod, I must download from radio, import CSV of memories from previous saved set. Must select Yaesu 857, NOT 857(USA) as it used to want.
Before Mod: Jumpers on 1,2 only.
After Mod: Jumpers on 6,7,8,9 only. Note unusual jumper numbering.
