eniac Posted October 27, 2009 Share Posted October 27, 2009 .. a lot of accustic feedback at first I have to say sorry for my bad english. School ist over for years. i'm Stefan from germany and I fitted a clansman IB3 with two CB2 in my Swiss Armee Pinzgauer. Hunting for two of the ANR Headsets counts me 3 monty but now the system is complete and installed in the Back of my Pinz. The first test take place on an trip through the western Alps. And here is my Problem. I use the standard ANR headset (figure 17 -> http://www.ferret-afv.org/manuals/clansman_wiring_harness_and_control_boxes_description.pdf ) and if I turn my head with the set's on I get some hum noise. I think it is an accustic feedback from the ANR system. Dose anybody have an Idea to get rid of that :argh: noise ?? Dose anyone have the operation manual of this system (ANR) ? for any help I would be grateful Quote Link to comment Share on other sites More sharing options...
Tony B Posted October 29, 2009 Share Posted October 29, 2009 Turn GAIN down or Volume, cover microphones with a spong wind deadener. Quote Link to comment Share on other sites More sharing options...

Wind deadener will cure the majority of your problems - if you haven't got the right ones you should be able to get them from C&S Tat - http://www.emlra.org/club%20shop/cstat.htm Quote Link to comment Share on other sites More sharing options...
Tony B Posted November 1, 2009 Share Posted November 1, 2009 Or soft sponge and gaffer tape. The main reason you get feed back is the microphone picking up noise from the speacker, then retransmitting adn so on round and round and round. Extrenious wind noise will cause this. Check the earth screens are correctly fixed. You may be getting interfrence from the vehicle electrics. Quote Link to comment Share on other sites More sharing options...
AlienFTM Posted November 6, 2009 Share Posted November 6, 2009 (edited) Observation. CVR(T) arrived in the early '70s with a hybrid radio harness to offer Clansman functionality with Larkspur equipment (because MOD could not afford to give CVR(T) to the Royal Armoured Corps and Clansman to the whole army), including for example Live I/C through the helmet boom mike. This allowed a working A-set in the left ear, pressel-activated; monitor B-set in the right ear and Live I/C also in the right ear (with no need for for pressel activation because it was live). This was the commander's normal working position. Gunner / operator would reverse A- and B-set on his junction box (work B and monitor A) IF there were two nets active. As a former Battlegroup HQ Control Signaller, unless the tactical situation required (for example being attached to an Infantry Combat Team) I always somehow managed to have BG Command Net on the B-set so I could get the bigger picture. In the sabre troops, Combat Team Command Net was always on the A-set (In FHQ, BG Command Net was on A and CT on B: in RHQ, Divisional Command Net on A and BG on B). Troop chatter nets were frowned upon but if a troop needed isolated comms for any reason, they could switch to an alternative CT Command Net frequency and work undisturbed. My point is that always on CVR(T) and always on Clansman, Live I/C was available in the right ear. For the majority of a period of seven years when in the field I had Live I/C with the wind whistling in my right ear (with or without sponge mike cover) as our Recce Regt hurtled back and forth across the North German Plain and the 1 (BR) Corps FLOT. I transferred out in 1982 and very shortly after posting to another unit, I was subjected to a hearing test which revealed that my hearing was reduced by 85% in my right ear. I was blissfully unaware of this, but have always used it as an excuse for not hearing anything my wife says. A couple of years later toward the end of that tour I was subjected to the same test again, which revealed that my hearing in my right ear was now at 100%. The only conclusion I have ever been able to draw is that the wind whistling over a boom mike into the right ear can cause long term (but mercifully reversible) damage to that ear. Make of this what you will. Edited November 6, 2009 by AlienFTM Typos and clarity Quote Link to comment Share on other sites More sharing options...
Tankboy Posted March 16, 2012 Share Posted March 16, 2012 Did you every get a resolve to this issue? One of my buddies is having the same problem with his Clansman ANR headsets. Quote Link to comment Share on other sites More sharing options...
timbo Posted March 16, 2012 Share Posted March 16, 2012 Same problem = same solution ie sponge mic cover..? Alien old chap - i always enjoy your posts but goodness knows what Stefan from Germany made of it..! Quote Link to comment Share on other sites More sharing options...
andym Posted March 16, 2012 Share Posted March 16, 2012 The first thing is to ensure you've got a matching set of bits - ANR boxes, pressels and headsets. You can't mix and match between ANR and non-ANR. Andy Quote Link to comment Share on other sites More sharing options...
ferrettkitt Posted March 16, 2012 Share Posted March 16, 2012 My pictures need updating will do so in the summer I would swap headsets and pressells about to see if the noise follows the headset around or the pressell. It could be a loose wire or dry soldered joint Quote Link to comment Share on other sites More sharing options...
