KENWOOD TH-D7A TX BAND MODIFICATIONALLOWS TX 136 TO 173.995 AND 400 TO 479.995
It has been suggested that modifications to the TH-D7a may somehow void the manufacturers free firmware update that is available. While I don't believe my modified transmitter will have any problems in getting its deserved firmware update, I did however save both diodes for future replacement if it ever becomes necessary. This may be a good idea if you were ever to want to "trade in " your radio to a store, or if warranty work is needed. Just in case.
There is another modification that can be done instead of the one above. It will have a smaller effect on the available TX frequencies. However this modification is easier to do and much easier to reverse. Follow the same directions as above, but #8 is optional and probably not necessary. When you get to #9 just cut or remove the green wire. Do not remove any diodes. This mod will have the following effect on TX freq:TX frequencies of 142.000 to 151.995 are possible - TX frequencies of 420.000 to 449.995 are possible. No change to RX freq with either of these mods. Amsterdam CLICK HERE AND YOU CAN VOTE FOR OUR FREE PACKET RADIO WEBSITE IN THE TOP 100 WANT A TOP RANKING ?
