Installation of a QH 40 A crystal heater into a standard JRC JST-245 TCVR

Reference - QH 40 A - Installation of a crystal heater into a standard JRC JST-245 TCVR

Here are some photosof my installation of the QH40A crystal heater into a standard JRCJST-245 tcvr. The 12 V DC and ground supply are right next to the stdoscillator crystal and DC voltage is present when tcvr is switched on.I do have a TXCO for the JST-245 [not installed] but instead I fittedyour QH40A, I did not need to remove the synthesiser pcb to enable meto fit the QH40A , it can be fitted without removal of any parts orpcbs. I know some amateurs use the JST-245 as a transverter driver for2m contesting and EME. I use mine on 50mhz for EME, this morning at0430z I worked ZL3TY via EME on 6m using JT65A mode, with the JST-245as my transmitter.
