TRIO TM-2550E 2 MTRS Mobile FM Transceiver 144-146 Mhz. Condition is "Used". 


Fair condition (See pictures for condition).


Came to me as fully working." Tested with another radio at the side of it, and it receives ok" was the statement used !!!!!


So, it had poor receive, more than 20dB down. Replaced the front end transistor and re-aligned and is now a good -123dBm for 12dB SINAD, and the squelch opens at -127 dBm. Transmit Low is 4W and High 34W.


I can now say it is "Fully Working".


Comes complete with Non-standard Microphone and Fused Power Lead.


Dispatched 2nd Class, Tracked and Signed. £9.99
