Could I please remind all members to sign postings with a name, and a callsign if you have one?
If you don't have a callsign, it is always helpful to give some indication of where you are located, particularly if itens for sale are involved.

Unknown Amplifier Modules
I am looking for informations about unknown for me Power Amplifiers modules and working with them splitter and combiner. PA module is build around pair of D1005UK DMOS transistors. I was told by lady in military surplus company that in dissassebled amplifiers it was in total five PA modules plus one power splitter and one power combiner. But she was not able to say more. I was trying some reverse enginering and it looks like power supply is 24-28VDC ( no magic here). Voltage stabilizer for bias is TI 750M10C. There is also a kind of control circuit build on SN75177P. Only on Power Combiner I can see numbers similar to NATO numbering 3513-172-464-7. But nothing on www on that. As I secured few sets of above its woth to look for information, diagram.

Re: BCC540
Hi Gerald.
I am new on Racal -manpacks group. Recently I bought from military surplus company two BCC540B ATUs. One was died but anoter hopefully was working well. I managed to to made working first one by replacing power pass thru relay and few resistors. I am looking for BCC540B technical service manual or just circuit diagram. Version B control board is completly different from revision G. Rev G manual is available on the www. Could you help please? Vy 73 Mietek SQ5PTQ ex SP5HBT |

Re: BCC-66H
Hi Dave, many thanks the info, that is what I thought but I needed to make sure!, The basic radio is a manpack for 12v battery use and in the vehicle configuration with the added module they run from 24v. VIA the addon module, excellent, I can play now !, Any idea which pin on the VIA for the BCC-66 is the positive, normal Clansman I believe is A - positive yes.

Re: BCC-66H
The radios in both cases uses 12v through the audio connectors or on the rear terminals. The battery for the BCC66 is the MA4025 it's also used on the PRM4090,4031,4021,MA4041 and the Cougar SMT unit. So only connect 12v to the bare radio.
The VIU supply is 24v and it converts the 24v from the vehicle to 12v to operate the radios through the audio sockets. In vehicle configuration the BCC66 and BCC567 are termed VRQ316. Regards Dave g1jwg? |

Re: BCC-66H
Some confusing information appears, I have also A TRA967 with it's amplifier, the set takes a 12v battery yet the manual says the set ( and the amplifier ) can be connected to a vehicle supply ( 24v ) and the same in the manual for the BCC-66H and the VIA, mentions a 12v supply AND being connected to a 24v vehicle supply through the VIA unit, so which supply do I use ?for the basic radio and/or with the accessory units for either radio.

Leighton,

Jaguar V, great radio. I was working in the Racal labs at South Ruislip
when the radio was designed. It uses Clansman 7 pin connectors rather than the
earlier type as used on the Syncal 30 for example.
?
I recall Dave, PMR conversion, has the handbooks for this set,
they include the circuits etc.

BCC-66H
?I have recently obtained a Racal BC-66H Transceiver with it's attached Vehicle Interface unit BC-567HE, I have found the basic manual for this kit but no circuit details giving handset/headset connections etc, I also have the TRA 967 kit which has headsets etc with it, are these headsets useable with the BC-66 ? I would think so as they are for a Racal set, I also have the auto atu and antennae base for the 967, can this be used with the BC-66?.Any advice as to setting this BC-66 up and details of circuits etc would be appreciated.

Re: Final transisters for racal 921 syncal 30
I fitted a pair to mine 10 years ago. I still haven't mustered the bravery to power it up.? I used equivalents, forget the part number. Your point is probably very valid about the ALC circuits. I will pay that the utmost diligence. On 3 December 2014 at 10:03, gmb_uk2005@... [Racal-manpacks] <Racal-manpacks@...> wrote:

Re: Final transisters for racal 921 syncal 30

the 921 uses 2N5026 the syncal 30 931 unit uses 2N5070 my devices ent south long ago it is very easy to put a stud rf device and use it? that is what i just did only change is the emiter resistors |
