kquella

Hello, I recently purchased two TK-880's and went ahead and updated both of their firmware and I wrote both radios with the same .dat file which I created in KPG-49D. They both have all the same identical settings, simplex channels preset, repeater channels preset and even the same button config. I'm running 50' of RG-213/u coax and a Diamond x30a (for now) antenna. One of the units transmits to the repeater flawlessly and simplex as well. Basically the unit is perfect as of now. The 2nd unit will only transmit simplex which it also does perfectly but for some reason when I try to speak to the repeater I have no transmit ability. I've tried three different mics just for the heck of it. Power is coming from the same power source (fully charged deep cycle battery on my bench for now). Please let me know if there's any other details you may need. Thank you,

Hello, My current version is B5DC which I believe is one of the oldest firmware versions these came with. I have search High and Low for this firmware. A guy on youtube had a link but now appears broken as well as some other forums do not have attachments. Anyone have this by chance or can they point me in the right direction? Mine is the "H" version TK-880H-1 V2 if that matters? I don't think the H version matters for firmware? Thank you,
