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.

I don’t know what radio set(s) this mount goes with yet, or whether it’s from the WW2 era or later. It is constructed differently than the FT-505 that I borrowed and wrote about; that FT-505 was assembled from rails of cast (or possibly forged) aluminum riveted onto a stamped sheet aluminum base, while this MT-702/U is a single cast piece. I’ve heard from another FT-505 owner who says his mount is a single casting, though. “MT-702/U HUBBELL & MILLER CO” is cast into the base portion of the mount.

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? ;)

  1. So how is Dennis these days? That mount can make life easy for BC-1335 collectors. Either spend a lot of money having a Chinese company manufacture some BA-70/U’s, or use one of Pietro Noto’s converters. The mount I have is just for the BC-1335. It has shocks, is very heavy, and until I buy an old van and have it attached to the floor or raised up on some angle brackets so it is near my hands, it will remain a curiosty.
