I’ve just obtained a WW2-style packboard with an MT-702/U radio mount fastened to it. It’s similar to the FT-505 pack mount that I wrote about previously, and a BC-1335 transceiver will fit on it. However, unlike the FT-505 which has a wide spot for the BC-1335 and a narrow spot for a CH-191 battery box, this MT-702/U has two wide spots, each of which is the right size for a BC-1335.
If you know what radio set(s) this MT-702/U goes with, please comment below.
Dennis Starks identified my new mount:
Your pack board is equipped with the later style Korean War vintage mount for use with a BC-1335 & it’s companion dry battery box. It had the same foot print as the BC-1335.
Early portable variants of the BC-1335 used the already available CH-291 wet cell battery box & the radio’s own internal vibrator power supply. Operational time with this configuration was limited so the BC-1335 had a connector added to the front panel to accept a multi voltage power source. The CY-740/PRC battery box housed multiple voltage dry cell batteries.
My BC-1335 is in the WW2 configuration, without the additional dry cell connector, and my CH-191 box (retrofitted with six 6V gel cells in parallel) provides enough battery capacity for my use of the set. So, I’d much rather have an FT-505 mount for my SCR-619 set. Anybody wanna trade? ;)
