Strange Racal set


Alan Tasker
 

I have a tubular frame that mounts a TRA-967 transceiver, a TRA-970 power amp, an MA-972B ATU, a small junction box, and a (missing) battery box. The battery box would be about 13.5" long by 3.25" wide by about 4.5" deep. The box would have two mounting screws about 9.25" apart.

Does anyone have a clue on a Racal designation for this assembly?

Is there any source for the battery box?

Thank you. Alan WA1NYR


 

Very interesting - nothing in any of my information about an
assembly like that, Alan.

Those battery dimensions fit the MA934 battery exactly, both in
external dimensions and for the fixing bolts. Normally of course
these are 24 volt (for the TRA931, etc), but I suppose Racal could
have easily used the same case and configured the cells inside
differently. Might be worth a call to one of the suppliers who still
list Racal manpack batteries, and see if they know of a 12 volt
battery in this pack?

Actually, according to the Racal spec, the TA970H can have a supply
voltage between 14 and 32 volts - does it contain a regulator to
supply 12 volts to the '967? If so, that suggests they may be using
the standard 934 battery. These have turned up on eBay in the last
few months, so they are around.

According to my information, the MA934 is one of the few batteries
from this generation of manpacks that is only available asa
rechargable, and doesn't have a dry cell equivalent.

best regards,


Bob

Actually, I think there is a regulator inside to supply the 967 with 12 Volts.

Where do I find specs on the 970?

Thank you.

Hmm, afraid my information is pretty sketchy, Alan. The "Concise
Catalogue" has a picture, but just says " TA970H, 25 watts, 14-32
volts, for use with TRA967"!
