I am looking for one or two Symmetricom/Telecom Solutions TOAA 090-40028-10 1/5/10 MHz output clock modules. I am looking to build a GPSDO from a Telecom Solutions DCD 519 shelf that I have. I am willing to buy the above modules. Or, willing to trade. I have several of the DCD ST2E 40017-02 Rubidium Oscillators, DCD TOTA 40012-02 T1 output cards, DCD TOCA 40011-02 timing output composite clock, DCD SAI 45014-02, DCD CI 40010-01 and MCA-5 45015-01 cards to trade if interested. Let me know what you have! Thanks and 73, de KA2KQM.
