  1. Etch primer has worked for me. You need to dig the corrosion out of all the pits first.
  2. Richard, it is 03BB33, a Mk1. Gordon
  3. For my Ferret the Merlin report shows it as RY LAD from 5/12/89 until 11/5/93. The record card for this period shows Code change from 0122-4101 to 0122-4000. I assume RY is Royal Yeomanry but do Merlin reports normally go into such detail as LAD? If the vehicle was transferred from the LAD to a squadron would Merlin know, or care? Gordon
  4. Only if you are going to be filling it from unknown fuel sources in unknown jerrycans.
  5. The Series 1 has the same thing. I've never had an issue with mine in decades of use, but I have had them rot and fall off. Indeed, I found mine in the bottom of the tank only last week.
  6. Re orange. In the 70s I had some ex-MoD paint I was told was red lead primer. It was bright orange, and wonderful stuff. I did my Landrover chassis and bulkhead with it in 1980 and it is still there, and still bright orange where it shows thru the x layers of subsequent paint..
  7. It isn't a balun as you are going from unbalanced co-ax to an unbalanced whip. I believe from memory that it is an auto transformer designed so that there is a DC path from the whip to ground/vehicle chassis in case of contacting overhead power lines. It may or may not work effectively on 2m. Being designed for the mil band the ferrite may not be suitable. I think I would remove it and just feed the co-ax straight to your quarter wave whip cut for 2m. Or you could do some tests with and without it to some distant friend and try and see if the received signal strength changes with and wit
  8. I was told the tale that an MAN wrecker was sent out to Canada and MAN remotely killed it because they thought it had been stolen. The Army were not amused because at the time they did not know MAN had the capability. I have also been shown the switch on the dash board that bypasses all the things that would normally stop it so you can at least limp it off the battlefield if a sidelight blows.
  9. MFJ is an american manufacturer of amateur radio kit. Gordon
  10. 24v FFR is designed for radio fit so everything is screened. Coil, plugs, alternator, distributor etc etc. So you won't get bits in Halfords. Unless you want to fit radios why have to buy two batteries when they die? You see what I'm saying, unless you need the 24 volts stick with conventional bits and bobs and 12 volts.
  11. Speaking as a Ferret driver with elderly ears I have found that the Clansman kit doesn't really cope with the background noise at normal road speeds. That is using standard A vehicle headsets, the ANR ones might be better. I am though advised by someone who knows that some IB boxes are better than others. Indeed the IB3 I know has an internal adjustment for audio level. I've wound mine up this winter but have yet to see if has made any difference.
  12. He is active on other fora. His call sign is his father's, re-issued. gmb
  13. Not sure about RCU but that looks awfully like a "Crew Box 2 Set" in which case there will be two sockets on the bottom labelled Audio which are logically enough for head/handsets. The two 12 way connectors, assuming there is one on the other side, are labelled Harness and are used for daisy-chaining crew boxes and the IB2 or IB3 interface box. Also things like the Commanders Box. I believe in armoured vehicles the daisy chain was taken back to the IB box so as to create a harness ring main, giving some redundancy in case of damage.
  14. I accept you are doing this installation from documents but speaking as an operator I would be swapping the 320 and 351 around. As shown the 320 would be a right pain to set up and adjust because of control access and visibility. The 351 is designed to be adjusted from above, so to speak, whereas with the 320 you need to be looking at it from the front.
  15. Bog standard R1155 HF receiver as used in most Brit medium to heavy aircraft and air-sea rescue launches. Commonly called a"Lancaster" radio. Not particularly heavy as for airborne use but some were in steel as opposed to aluminium cases so would be heavier. The pictured one looks pretty tatty and rusty but seems virtually unmodified, which is quite rare nowadays. They need a fairly specific power supply which in practice means home built. I wouldn't put power anywhere near it without a close internal inspection. There are lethal voltages in there and if it still has the original rubber insul
