Signal One CX-11A transceiver
Having been in storage, the radio avoided the wear and tear from daily use and multiple owners The switches and pots as well as the rest of the radio is in very good condition. Since purchasing in 2007, the radio has been completely gone through, and the following was done: – Sherwood matched 8 pole filters installed – Marginal tantalum caps were changed out – The 9 power supply electrolytic caps were replaced with fresh stock Mallory and CD computer grade caps (not easy, or inexpensive). 3 CX-11As have lost one or more of these original 35 year old caps in the last year, causing damage to the radios. TCXO added to replace 10mhz crystal oscillator – BFO crystals replaced with new production ICM crystals ; 43.1, and upper / lower SSB – 43.1mhz crystal heater adjusted (resistor change) to cycle at 60 degrees C, instead of 80 – Three tab -15, -15, and 5 volt regulators changed to new versions, with better protection. 5 Volt regulator was changed to new Micrel higher current version – Fan replaced with more quiet model – BFO aligned – Synthesizer aligned – Switches cleaned and lubed – PTOs cleaned and lubed – New thermal grease on regulators, TX drivers, PA transistors Other than above, there have been no other modifications to the radio. The front panel shows no wear or marks, the cabinet has a slight rub mark on the lower right side at the back. The original fan and crystal filters will be supplied with the radio. The radio also has the original box, and manual. This is a 35 year old radio that has been carefully maintained and covered when not in use, the work that I have done makes this a radio that can be used daily. There are at least 3 hams, including myself that can work on CX-11As should a problem arise so they are not orphans. Thank you for looking, Bob K4EIR.
