Thanks Steve. Found the baud rate by looking at the PC COM port used to down load from the radio, but still haven’t found the HEX files for the firmware flash. Probably all for naught as I can’t get the thing into PROGRAM MODE. Unless I find a way, it’s a door stop.

Trying to flash the firmware of an old TK880H Version-1. First issue is that I can’t find a HEX file for the version-1 to update with. Second issue is that I don’t know what baud rate to flash at since depressing the scan key when powering on the radio does not provide a rate to use for the update, obviously an important technical setting. Anyone have any help for this? Thanks in advance for your response.

Thanks to you too Socalgmrs. Think I’ll study the Professional Engineer’s R56 reference and then take your advice. Good call!

Thanks Steve. Scanning the R56 I can see I need the education. Thanks again.

It appears that when assembling my rooftop antenna system I can attach my coax lightening arrester either to the SO-239 of the antenna that will be clamped near the top of my 7-foot aluminum tubing mast or, I could splice it into the LMR-400 coax with an SO-239 and a PL-259 end near the bottom of the mast just before the coax enters the wall of the house. The base of the aluminum tubing mast will also have a ground wire attachment and both ground wires will be fixed to an 8-foot ground rod some 25-feet away, 4-feet out from the house. My question is ‘in which of these 2 locations should I install the coax lightening arrester’ regardless of what rigid antenna is at the top of the mast’ ?
