content: Hi All,A bit of a reach here. I'm looking to source replacement microphone for a Barrett 2050( Barrett BCA20023). The radio is installed in a health outpost in a remote village of Papua New Guinea, and is the only link to the outside world for the folks there. The current microphone has had its cable completely ruined (rodents probably?). I'm not looking for a handout. If you might have one or have an idea of how to source, please send me a message!With Thanks,Tim

content: It did turn out to be one using an RJ45, just as I feared.As the mic also has up/down channel controls, you are probably better off buying a new one.In the USA there is ;-https://www.satelliteworldstore.com/product/bca20010-barrett-2050-hf-radio-hand-microphone/and in Oz:-http://www.pacificrim.com.au/bca20010-barrett-2050-hf-radio-hand-microphone.htmlbut it may be best to go straight to Barrett.https://www.barrettcommunications.com.au/2050-hf-transceiver/Alternatively, if the actual mic assembly is all right, & the cost of a new one is horrifying, you may be able to repair it, either yourself, or by getting an Electronics repair business in PNG to to the job.PS. Obviously, with you in Canada, the shipping would be nightmarish, as would be negotiating with an Electronics repairer in PNG, so, unless someone has one sitting around unused, it looks like you will be stuck with buying a new one.

content: It might be worth sending an email to Miles Electronics in Cairns QLD they list on their website that they sell Barrett gear. Being the closest Australian city to PNG they probably will have some experience with PNG. So assuming that they can source the Mic they might be better placed to deal with the logistical problems PNG can present.If you want to send someone up to sort it out for you let me know. An adventure in PNG sounds like a blast.M

content: you might also want to look into getting a guard metal or something around the cable, it sounds very important to keep that radio running. repair and prevent

content: I think the issue is that the Mic is in PNG and it looks like the OP is in the states. Rodents have a particular fetish for insulation. I have seen them chew through an aluminium enclosure to get at the insulation of fibre optic cable. Or destroy meters of cat cable by only eating the outer insulation. They are bastards that must all get together and think of ways to damage comms equipment in the most creative ways. And that’s just with their teeth what they can do with biological waste is even more brilliant.M
