Malteser Posted June 3, 2012 Share Posted June 3, 2012 Does anybody have any info on the Racal PRM 4031 please. I know the basic spec on the radio but unfamiliar with mic/headset types. Although the clansman uses the 7 pin similar socket obviously is`nt the same. Are they readily available, many thanks, Ian. Quote Link to comment Share on other sites More sharing options...
g0ozs Posted June 3, 2012 Share Posted June 3, 2012 Ian The full technical manual is available to members from the Vintage & Military Amateur Radio Society archives - the subscription is £20.00 pa which is probably less than a dealer will charge for the manual ! The headset and handset to fit it are ST711015 and ST711014 or the loudspeaker is MA·998. There is a free specification sheet at http://www.pmrconversion.info/manuals/racal/PRM4031.HTM The audio pinouts - Figure 3 - are about half way down. Pattern 104 connectors to fit are available from various manufacturers and dealers - you could try Farnell or F.C Lane or Weald Electronics - these can be used to rewire Clansman audio gear, or you could try to dismantle the plugs and change the keying. You may also find the Racal-Manpacks Yahoo group helpful in your quest, Regards Iain 73 de G0OZS Quote Link to comment Share on other sites More sharing options...
