Radio types fitted to 6x6 Landrovers

[303Gunner]

What radio types are fitted to the 6x6 Landrovers. All of the 6x6s are prepared for fitting a radio by the provision of a radio distribution box behind the passenger's seat and a reinforced Antenna mounting on the top of front RHS wing. Some body variants also have an additional Antenna mounting point on the top rear of the body module.

So far, only 2 6x6s released through the auctions have ha evidence of radios actually being installed, both of them Ambulances.
50-645 has the basics of an AN/PR77 radio set being installed. In the cab, in addition to the radio distribution box behind the Passenger's seat, behind the centre seat it had a AM-2030 Vehicle Mount Chassis, and an MX-6707 Antenna Base on the front wing. All the connecting cables were still present. It has been mentioned before that the PR-77 Radio is the Set most often fitted.

202-058 has an Antenna Base fitted, and pending on-site inspection, presumably interior radio components in the cab. However, the Antenna Base is not an MX-6707, and is a type I don't recognise. If the ARN is an RAAF rego, is it likely that a different Radio Set was installed with a frequency range more suited to Aviation ? Does anyone know which Radio Sets are used by RAAF ground vehicles?

What makes you think the base isn't a MX-6707?

I'd be almost certain it was for a PRC77 VHF set.

RT-F100, RT-F200 & AN/PRC-77

Not correct. Only selected (specialist) 6x6 vehicles are Fitted For Radio. Most 6x6 do not have the necessary battery set-up to operate radios.

Not correct.

RT-F100, RT-F200 & AN/PRC-77.  RAAF also use additional hand held radios for some airfield work.

Because it doesn't look like one!

[AGAS 5]

I can't recall the nomenclature off hand, but it's the antenna for the RT-F200.

P.S.   at a guess.....  I can't see any reason why it couldn't be used for a AN/PRC 77 Set as well.

But that is a different vehicle!

I commented on the one in the post.




And that sure looks like an MX-6707 to me.

OK, I can now see there's two vehicles in the post, the sun was on my monitor at work and the ARN/RAAF RN link was v hard to see.

Appear to be a fairly common mount 303

Radio setup in the second and third photos may give some clues. Could they be for the Raven sets?

Interestingly, the fourth photo shows a 6x6 with both types of aerial mount above the cab.

The Ant. Matching Unit shown on the Ambulance is for the AS-3900 Ant system.
Looks like a AM6707 but doesn't have the Freq. Matching relays inside.  Mounting thread on top is much
larger as well so requires different whip sections.
Used for the SINGARS or RAVEN series of radios.
Similiar uses for the other Mount as well but not sure if it's HF or VHF

Only 2 6x6 sold with radio fittings?

Not so the rebuild in bne was fitted with all the gear.

Was that before Sep 2013, Juddy?

And when you say "All the gear", you only refer to the 24v charging and distribution system (which has been present in lots of vehicles), not an actual radio installation?

[juddy]

Every thing but the radio  yes.

Apparently the PRC77 sets currently in use with the Army reserves and cadet units are being retired. 

I wonder if they will come onto the market, be given away as foreign aid or be crushed.

[Phoenix]

Oohhh, how interesting.  I was only commenting to somebody the other day how they are becoming more common.

I was talking about this to the curator/guide when we were at Pucka. Apparently, he is expecting a large number of examples arriving shortly which he will put to use in display vehicles. He understood they were still "restricted" property, and was surprised when I told him of the number that were getting about in private ownership.
