I was very fortunate to be able to pick up an unused Kenwood TM-455A 430 MHz All Mode Transceiver (and its sister for two-meters, the TM-255A). Does anyone know if the TM-455A can be modified to cover the entire band? As it comes from Kenwood, it only covers 430 to 440 MHz. Thanks in advance for any assistance. 73, -Bill, WA9MXQ
