Apologies - last should have been addressed to Nick

Rog Louis Meulstee's site http://www.wftw.nl/swedisharmy.html has some information in English Regards Iain

Folks In the course of my shed & garage clearance I came across the pictured control panel - does anyone recognise it and can anyone find a useful home for it or any of the parts, before I resort to e-Bay or the skip ? I'm guessing a towed generator control panel. Free of charge if anyone collects or I'll be quite happy to post it at cost to anyone who has a real use for it if it goes before I move on the 30th Sep. Regards Iain

Dear All Sorry for delay uploading these - since no one else has sent anything from the MHAS event I thought it worthwhile to do so Iain

What is the smaller vehicle between the Gama Goat and the Stalwart ? Iain

There is a link on Brooke's site (http://www.prc.68.com) if you look carefully - the adapters for the HT battery replacement are made by Pietro Noto in Italy (e-bay ID inverter45 although nothing listed currently). There are few dummy D-cell batteries that could be used in series with a normal D-Cell to make the filament/heater battery replacement, but the combination of a dummy AA cell (readily available) and a D to AA adapter e.g. e-bay items 180952107358 and 360516055221 - I don't think I have ever bought from either seller so these are examples not recommendations, although I did something similar to use dry batteries in a PRC350 C-size battery cassette and get 12V out for ordinary ham radio gear. Regards Iain

Does anyone know if the demountable container was manned ? It seems rather lacking in headroom or is the cab taller than it looks ? Iain

Jack Quite possible - I have been around for a while ! I guess the most likely place if so is one of the East Suffolk / North Essex radio clubs or at the SAHS military vehicle days at Foxhall Heath ? I sold quite a lot of surplus items from my first few trips to Withams in 2009/10 on e-Bay and I am also a member of VMARS and occasionally appear on the 80m nets on Saturday mornings Iain 73 de G0OZS

I know our local electricity board (what was Eastern Electricity) replaced their Dodge 50s (RB44-ish) with Renault 4x4s that look awfully like a TRM and are still around - I think the issue for vehicles younger than the 25 years Nick has usefully pointed out will be whether the CoC for these will also cover a LHD military TRM2000 Regards Iain

Martin You might want to have a read of http://www.dft.gov.uk/vca/vehicle-importing/importing-hgv.asp http://www.dft.gov.uk/vca/vehicletype/type-approval-for-go.asp https://www.gov.uk/vehicle-approval/individual-vehicle-approval I am fairly sure there are already road registered TRM2000s in the UK (I remember they were being sold as gun buses after the supply of Simca SUMBs dried up) so it can be done. See: http://www.gunbus.co.uk/folder-17-trm-2000-gun-bus Good luck ! Regards Iain

Jack Welcome to the forum ! Iain 73 de G0OZS

Richard First of all good luck with the intermediate test ! The 353 always makes some fan and motor noise - it's nothing to what you get with the test switch in 'override' position and the fans on full blast however. Finding FM traffic on a 25KHz channel the 353 will tune to is difficult without prior arrangement given that the band plan is based on 20KHz channels - locally here in East Anglia most traffic is on GB3EF (51.720MHz) - close enough to monitor with squelch off. Wide mode without tone gets rid of the tone squelch and will hear most things albeit with low audio levels. The GB3MCB Mid Cornwall 4M beacon (70.025MHz) may be a viable test source even if it's not an FM signal - it should at least be detected as a carrier. Iain 73 de G0OZS

Also, Graeme at PTS Norfolk has the original 6 core + screen cable priced per metre http://www.ptsnorfolk.co.uk/100820/info.php?p=4&pid=5452443&ack=9 Regards Iain

Richard What length do you need ? - if you can wait I'll have a look in the garage at the weekend and I may have a drum of 4 core screened and can cut enough off for you - or if you are happy for 4 pair UTP data cable (8 core grey unscreened) I can do you a used coil of 10 metres or so for postage cost if I find it Regards Iain

Richard For new cable probably best to use 8 core computer data cable (ethernet) which is available as shielded or unshielded. But I suspect NOS Clansman cables will be cheaper (try gten98 on e-Bay). In the specific case of the TUUAM to ARFAT cable the ARFAT schematic in EMER Tels L212 says only the following pins are used: B: Silent Tune C: +28V E: 0V / Ground F: Tuner Key So you could probably get away with a screened 4-core cable. The usual general electronics suppliers (Rapid, Farnell, RS, Maplin) in order of rising cost will have something by the drum but I think only Maplin offer per metre prices. Try Maplin Multicore 4 way screened XR25C at £1.89/metre. Iain 73 de G0OZS

Richard I don't think it uses as many as six cores - I do have the pin out somewhere & will check Iain 73 de G0OZS

Today's batch - PM me if you want a high res version of any of these Iain

Still there tomorrow if you want to inspect them in person - about 1 mile east of Ipswich Iain

Richard2 The 321 TURF does the same antenna matching job for HF radio as the TUUAM for VHF (although it requires manual adjustment - the manufacturer offered an automatic tuner for the 321 but it was never adopted by the British army). The correct options for a 321 in a vehicle are 321 > BNC Cable > TURF 25W > Wire > Base No 31 via centre screw connection 321 > BNC Cable > SURF 25W > BNC Cable > TURF 25W > Wire > Base No 31 via centre screw connection 321 > BNC + 12 Way cables > Amp 250W > BNC + 12 Way Cables > TURF 250W > Wire > Base No 31 via centre screw connection 321 > BNC Cable > SURF 25W > BNC cable (and 12 way from 321) > Amp 250W > BNC + 12 Way Cables > TURF 250W > Wire > Base No 31 via centre screw connection In all cases the tuner can be used when static with a dipole or similar antenna fed via the coax socket on the front of the tuner, nearly always with better results. The SURF allows multiple 321s to be co-sited and use closer frequencies than would otherwise be possible without mutual interference. It loses some transmit power and receive sensitivity and adds extra tuning steps after each frequency change so is best bypassed even if fitted unless it is actually needed. There is no ARFAT (Adapter Radio Frequency Antenna Tuner) counterpart for the HF radios - it is only there to adapt the Racal TUUAM to the Marconi 353 which is capable of higher power than the Racal 351/352 it was designed for. The entire 321/322 system came from MEL and was designed to work as a set. If the Clansman sets were used for teleprinter traffic with a Trend dot-matrix teleprinter or a Larkspur-era Siemens T100 the Adapter Telegraph Radio (ATR) was used as the modem and a separate 24V to 240V inverter was used to power the teleprinter. I don't know anything about BATES specifically but I would have thought it doubtful that any pre-1980 system would have been based on similar principles to Wi-Fi or Bowman - probably more like cellphone short message service in concept with the central BATES acting as the base station and the gun or battery level stations with data entry devices acting as mobiles. It was written up in 1981 as an IEE (now IET) technical paper if someone feels like paying out for a reprint: http://digital-library.theiet.org/content/journals/10.1049/ep.1981.0266?crawler=true The best description I have found in the open literature is http://nigelef.tripod.com/fc_computer.htm#BATES which implies that most BATES installations were in FV432 family vehicles and older than the RB44 - he refers to LACS as a newer lightweight version sharing much of the software. Regards Iain

Richard If there are no antenna base brackets at the rear (I can see the mast occupies the left rear corner) then it makes sense there is no TUUAM position inside. The mast would have been used with an EVHF pineapple I expect. We really need the BATES or BMETS installation in RB44 EMER to be sure ! Regards Iain

Richard2 regarding >> when i bought my 353 i also aquired a pineapple base and 3 section antenna mast ? im guessing this isnt >> for vehicle use ? if so what vehicle antenna is used with a 353 radio and would it still require a TUUAM and ARFAT ? The 353 vehicle installations always used a 2m whip in a No.31 Mk 6 or 7 base with the cylindrical antenna base extension (which contains a transformer needed with the TUUAM), TUUAM and ARFAT. This covered 30 to 76MHz with reasonable efficiency and could handle the full 50W output of a 353. If only interested in the amateur bands covered by the 353 (6m and 4m) whips cut to 1/4 wave (1.5m and 1m) with plastic extensions to make up 2m and look right could be used instead at lesser expense (and probably equal or better efficiency). The EVHF pineapple is used on a mast for extended range when in a fixed location with a direct connection to the 353. A static station could also use a Ground Mounted Monopole but it probably won't work as well as the TUUAM & whip. The GSA with or without elevation kit can be used with a 353 provided it is on medium or low power as the GSA is really for use with the 351/352 and 350. Long range rear links used the inverted V wire antenna supported by a 9m mast (usually a 12m mast with 2 sections left retracted). As with the GSA and Pineapple this came with its own matching unit and the TUUAM would not be used with an external antenna. Regards Iain 73 de G0OZS

I can confirm that this will do what you need without any radios present. Just connect a 12-way cable linking the IB2 to each CB2 and connect headsets to the crew boxes - headsets go in crew boxes and all switches set to intercom. Make sure that all of the boxes are securely grounded to the vehicle body rather than depend on the ground lead in the harness cable by itself. I notice that the boxes in the listing photo have black front panels (so are earlier non-ANR automatic noise reduction ones) and need to be used with headsets having the older style black pressil boxes - I seem to remember that the gold ANR boxes will work with either black non-ANR or green ANR pressils, but only black work with the original boxes (because ANR need a power feed from the box). Worth checking if Doug can supply ANR from stock before ordering ? Regards Iain

Hi The SURF is intended to allow the 351/2 to be used with multiple co-sited radios e.g. in a hilltop repeater station. It protects the receiver from strong signals on nearby frequencies. SURF actually stands for "selector unit, radio frequiency". The connections are: 351 - BNC Cable - SURF input - antenna mounted on SURF 351 - BNC Cable - Surf Input - SURF - SURF Output - BNC Cable - External Antenna e.g. GSA 351 - BNC Cable - SURF input - SURF - SURF Output - BNC Cable - 20W amp - BNC Cable - External Antenna The SURF needs to be tuned for maximum meter reading while the 351 alone is transmitting. Scans of the manual may be found on the open internet at: http://www.land-rover-lightweight.co.uk/ClansmanB.html Regards Iain

Jak You will need in addition to a 353 1. Power distribution box 2. Power lead 3. ARFAT with 12 way and BNC leads 4. TUUAM with 7 way and BNC leads 5. Either side stalk or wing box 6. VHF antenna base (the cylinder below the rubber insulator) 7. Antenna mount no. 31 8. 2 steel antenna elements making up a 2m whip 9. Bench 10. Battery Box 11. Radio Batteries 12. Headset or handset Hope this helps Iain

Hi Note that there are two ways to do it - the photo attached is a soft top and uses a different top clamp that has jaws to grip the top of the tub at the other end of a short tube from the mast clamp. The bottom end can use the clamp pictured or a simpler mounting where the spigot at the bottom of the mast is fitted into a modified bumperette. E-Bay items 160930842021 and 290921969388 are the spigot and bumperette clamp. The universal top clamps do turn up from time to time although I see no current e-Bay listings. I attach a photo so you know what to look for: The top clamp pictured in your post are for fitting the mast to a vertical surface such as a comms body on a larger truck. They probably can be used on a hard top landrover although the side windows may be where you would really want to fit the top clamp ! Regards Iain
