I borrowed handles headset and portable radio so I could have a play with it,,,now I'm no expert on this stuff but so far every bit of this kit looks quality. Nothing is light weight crap it all seems to be heavy robust equipment. Hope it works as good as it looks.

Took some pics of both,,,. Some interesting features included,,,it has 2 PTT's,,,one in the cable with volume adjustment and one on the headset. It also has an extra plug on the cable which you would presume is for a different radio.

"""Well I was just thinking, I could make the offer of walking around pit lane looking all important and testing your pit lane comms...""".

How does that work tiger,,,I fit it,,,you test it.

Cheers

Well I wouldn't want all that heavy robust equipment hanging from an old mans head/kneck... You know, you're not as strong as you used to be Neil... :D

Plus, normally when ever I put something together I get someone else to try it... That way if it blows up or injuries occur, I'm standing a good 10metres away...

It actually looks nearly identical to the gear that I was using at Eastern Creek for Superlap last year.

If it is, those noise cancelling head phones are UNBELIEVEABLY good!

hmm been a while since an update.

Firstly, this setup is excellent. The quality and toughness of the components kills anything else I've seen right up to the big $$ stuff.

Secondly, the after sales service from PMD has been excellent. Quick answer of phone and email questions, and they re-programmed both radios to the new 80 channel setups + firmware upgrades at no cost. Even got a stubby cooler which was the clincher.

Finally....my car has interferance from the bloody wb 02 sensor controller. I've tried literally everything to seperate them, any time the intercom and 02 sensor are on there is interferance. I can't think of any solution but a relay to turn off the o2 sensor when I hit the push to talk button....any other ideas appreciated.

Move the cables away from each other? Run a shielded cable that is grounded?

Yeah I kinda skipped the troubleshooting, this is what I've tried.

Run the intercom off a seperate battery (ie no link to the car's electrical). Perfect

Run seperate earth for intercom (was shared). Interference

Run seperate power for intercom (was shared). Interference

Run sheilded + and - from battery to intercom, routed away from other wires. Interference

Add small (and later large) filter on the positive of both the intercom and o2 sensor. Interference

BTW the interference is not specific to the PMD gear, the Terraphone had the same issue.

have you tried running a diode on the power line as it goes into the O2 and on the earth cable and do the same on the PMD gear?

It would probably be useful to put a CRO across the power signals and see what the power signal actually looks like.

But a small setup with a few diodes and possibly a cap or two to clean it up should work well.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
