I uploaded the scan of the 160-meter conversion kit for the HX-50/HX-50A to BAMA. When I acquired the HX-50A, I went looking for a conversion kit and was very fortunate to locate a complete, unopened kit! After installing the kit, the drive, to the final amplifier, was VERY low. The output was well under 5-watts. No alignment of the coils would increase the drive. Finally, I installed like a 47 pf capacitor between the windings of one of the coil sets, either T-1003 or T-1001. I don't remember exactly which one. I seem to recall that it was T-1003 but I am not certain. After installing the coupling capacitor, the drive went to where it should be and the transmitter put out full power. I used the transmitter, for 160-meters, for quite a number of years before building a 160-meter transverter. After building the transverter, I sold the HX-50A so I cannot verify to which coil set I had to add the coupling capacitor. Here is the transverter: http://nebula.wsimg.com/78f8c72f3ed4da3c80cfa84485eb476c?AccessKeyId=5DDC3F25F0398F58962E&disposition=0&alloworigin=1 Glen, K9STH

The Hammarlund HX-50 Transmitter has 160 on it's VFO. However 160 was an option that could be installed when new, or added on. I wonder if anyone has either the add on kit, or possibly a junker with the needed parts There are 3 coils located over the band switch T10001- 1st mixer coil p/n P26786-21 T1002- Second mixer coil p/n P26786-18 T1003 Driver Coil p/n P26786-19 11.335 mc crystal I have also attached the Hammarlund directions, courtesy of BAMA on how to install the kit. Any ideas or thoughts would be appreciated _______________________________________________ Boatanchors mailing list [email protected] https://puck.nether.net/mailman/listinfo/boatanchors
