PC headsets usually (always) use electret mics. I assume Clearcom, like other cooms systems, use 200R dynamic mics, so you will need to find a way to power the mic capsule. These headsets are also very flimsy compared with the real thing. It might be worth looking at language lab headsets (if they still exist).

You have some concrete evidence to back up your suggestion that the BBC are incapable of balance or serious research ?? OT but the lack of coverage on the marches showing support for Soldier F that have been happening in London a lot in the past few weeks. Total blackout from BBC despite Sky giving it full coverage.... Briefly staying OT, TBF BBC News has actually covered the marches, though probably only on the News channel & local News, as it's really an "and in other news..." story, rather than breaking news. of which there is more than enough already. Sky is a commercially-funded rolling news channel with its own agenda.

I doubt if they dish out service manuals (the link I posted is the user manual for your DN360 - as you say the DN3600 is a different beast entirely). I've had some success in googling for service manuals, but haven't needed any for KT stuff.

Probably still not what you want, but http://www.ctc-produ...60%20Manual.pdf is the operator manual

Even taking into account David's comments on Belling-type plugs, some of are indeed pretty awful, what I would generally use for aerial splitting is RS 749-2490 https://uk.rs-online...ed%22%3Atrue%7D with decent metal, not plastic connectors. Over the short distances involved I don't think the difference between 50 & 75 ohms is going to be very significant (I assume G3s are 50 ohm; the G2 manual doesn't say, but G1s & XSWs are).

I'm a bit surprised that Screwfix only seem to do ones with F connectors, but unless you are a fan of these I would stick to bog-standard Belling connectors. The CPC price seems a bit high, so it might be worth checking B&Q, Wickes or Argos.

As Mac suggests, passive splitters should be fine, but you can do the job for a tiny fraction of the cost by using ordinary TV aerial splitters. Buy a couple of low-loss splitters & a few short TV aerial links, cut the links in half & solder BNCs to the cut ends. Or cut some BNC leads in half & solder coax connectors onto them. Then take a weekend-break with the money you've saved. When I was doing kids' shows I made up a couple of 4-channel racks (one VHF, the other UHF), each with a pair of 4-way wide-band TV & radio aerial amps in them. Both used standard Trantec aerials dangling in mid-air, though I did later treat the UHF one to a couple of el-cheapo 3-element Yagis. I should really have added a bit of filtering, but both worked fine without.

Many London Underground lines will give you well into the 90s for several minutes at a time on faster sections - loud enough to make conversation impossible. How do you factor that in?

If they are well-packed is it worth insuring them? When I used to do the occasional stint at a lighting suppliers we just added a layer of loose foam or scrunched-up brown paper between the outer carton & the manufacturer's boxes & sent them by the next carrier.

Kodak Carousel (regularly used for lectures for many years; now replaced by PowerPoint)) - slides will almost invariably jam in the mechanism unless they are allowed to warm up for at least 10 mins before operating the projector. Particularly a problem on cold days if the slides have just been brought in from outside.

Point taken. Have you found any other source of these since the demise of Maplin? My Sennheiser G1 & G2 receivers all use NT2-1 PSUs (2.1mm), but I seem to have acquired a collection of NT2-UK PSUs, which are 2.5mm, with a plastic collar at the end (presumably to make them even more difficult to pull out than the 2.1mm ones) & it would be useful to convert a couple to 2.1mm to keep as spares.

Not in my experience, I've made up loads of leads to suit and sourced from CPC or Ebay or radio rallies. I have a large number of S1/1000, S2, S3/300 &S4/4000 Trantecs, & although the marked voltage & current vary between different PSU ranges they are all 2.1mm, centre +ve.

If you are buying 2nd-hand you could always open up the unit & solder a USB flying lead to the PCB. which would let you use any 2A phone-charger.

Debatable........

That's really neat, but does involve surgery on the speakers - not always possible, or desirable :(

MLEC are (were?) the official Trantec service people. Trantec lost their in-house service dept after they became part of TOA.

It's the length that matters. Ideally your aerial is 1/4 wavelength at the appropriate frequency, though Trantec seem to use 1/2 wavelength centre-fed aerials on their S4.n range receivers. In theory your homemade helical aerial should be fine.

How long your effective aerial would be would depend on whether there is any air-gap between the turns, in which case it would be much too long. I have made whip aerials for UHF Trantecs using wire from dead lampholders (nice & stiff) soldered to bits of sawn-off brass bolt, with the whole thing covered in black heat-shrink. They seemed to survive hires to kids groups (to save the "it won't work if you wrap the aerial round the pack" scenario the VHF ones only ever go out on hire with "rubber-duck" aerials).

That's a bit of a downer :(. My local disco hire shop has a Mr Fix-it who can replace G1 switches, but this sounds a bit more serious. As mentioned in an adjacent thread, used SKMs come up on the usual auction site at (sometimes) sensible prices, but it sounds like you'd be the one stuck with sorting it.

In that case a personal visit to his office, with a polite "I've just come to collect my cheque" may do the trick - it's worked for me on a couple of occasions. Questions to consider - Who should have paid you, the individual or the company? Did the company's MD & FD sanction the sponsorship, or was it just the individual? Did the event make enough money to cover its costs (including your fee) & still raise money for the charity? I would leave that for later (starting with a phone call). I've had one of those, though the amount was considerably more. One TV studio I did odd days for only got around to paying just before booking me for the next, so when they went bust I lost my last day's fee, & a facilities company I did a lot of work for tended to leave paying outstanding invoices till a few days before their Xmas parties, attended by a lot of important customers, many of whom I knew from my BBC days.

Is this an advert I see before me ??

All good advice from Timmeh, but a "I really don't want to have to take legal action, but ......" note sent with a copy invoice by signed-for post is a lot quicker if it is a genuine oversight. A threat to put them on the BECTU blacklist can also get a rapid response from those who would prefer not to pay, but if they really are a bunch of shysters it might be worth considering whether you would be better off cutting your losses (depending on the amount involved) & making sure it doesn't happen again.

Was this a Charity event or a "charity" event (they tend to work to different rules)? It's an unfortunate fact of life that some event organiser are keener to pay than others. For people or organisations I haven't worked with before I always put "cleared funds before the event" on the quote (they will have had to pay the venue in full at least 2 weeks before their event, so it doesn't seem an unreasonable request). Sometimes this produces cheques weeks or even months ahead, sometimes it means collaring the money-man before he leaves the building & a couple of times it has meant a visit to their HQ to wait while cheque-signers were summoned, but while I've been short-changed a few times, I've only had one total non-payer. Unless this was a charity you know all about it might be worth doing a bit of research into their organisation & officers - embarrassment can be far more effective than threats of legal action.
