I have to admit that when I went through all this ( and all the associated hassle and inconvenience of course ) I eventually gave up and resorted to e-bay and used a " 12V RF relay 2CH " (at about a tenner with two fobs.....)

Although it meant I would have to carry an additional fob around at least I could use it for two really irritating p38 'features' so I can now, and with the press of a button:
1) Cut off the power to that garbage LR Gen 1 Rcvr. (and remove bogus RF BECM wake-ups and lock-outs etc)
2) Cut off power to the EAS relay whilst parked (and remove those BECM wake-ups and its 'overnight bag dance')

After all the lock-outs and flat batteries etc I really could not bring myself to buy a £300 LR rip-off Gen 3 Rcvr. due to their really dire original design/s !

Now also considering a 4CH device (eg. see ebay item 371891099809) so I can just flash my lights (and/or indicators) remotely too.....
(Note that this cheap Chinese RF/433 stuff often has quite a range and so may affect other Gen 1 Rcvrs. so must be used wisely !)

So have we got an idea what sort of header the key receiver is looking for? Sounds like the sort of thing an "aftermarket" box could be created for.

Unfortunately it's not really the header that is the most significant part but the (proprietary) rolling code immediately behind it that counts !

I'd think that high-powered "wideband" RF noise can still overwhelm the receiver. Maybe it's smart enough to think it's being attacked and lock itself down? Doubt it though.

I put a 'scope on the back of my own (Ist Gen) Rcvr. once and was amazed at how much RF stuff it picked up, from frequent random bursts to very infrequent and slow pulses: It was basically acting as though it was a wideband Rcvr ! Some of this impinging RF (if powerful enough) will probably swamp the front end of the Rcvr. too. But the main problem I suspect is the BECM seems to behave as though it counts RF pulses etc (from any/all sources) and then may 'get difficult' beyond a certain number of what it perceives as multiple attempts to communicate.... Didn't establish exactly how many bogus pulses it took to upset the BECM like this but it may have been a lot (20+ ?) which can happen in some places in a few hours of course. (Note for this 'test' I basically stood next by the car continually operating a non-LR but 433Mhz 'plipper' -for some time- until the " Key Code" lockout showed up - and it didn't always do this either... aka 'a non-conclusive experiment' !)

Know what you mean JMCL but I don't think we fully understood that the rrnet forum exists only for TOAD's amusement; And Hell would freeze over before any real unbanning could happen; Clearly he will read all this thread and enjoy it; It gives him an actual reason to exist !!

I read your list JMCL with interest and reaised the one main thing I have learned from P38 ownership: NEVER to say 'it's just 5-minute job'...
as I swear this thing is just a 'Rubik's Cube on Wheels' !

So I say, put the links back..... Makes sense Gilbertd; Similar on other fora I frequent.

Sorry to raise it again but the more 'under the counter' vendors like Toad/LeftLane/Scotty certainly could be A-holes about it at times......

Ah, so it was all your fault then ??

Not sure which other forums/fora you are referring to there Gordon, but from other fora I participate on the problem starts when 'members' only offer 'services' and really not a lot else... (eg. Like Scotty on that 'other' site where your reasonable 'Don't Be An A-hole' advice their Mods. ignore).

Not sure either -other than Sh*tParts (with their 500% mark-up on bad quality stuff)- which truly 'commercial services' are making a mint on P38s to be fair....

Anyway, as previously mentioned, and speaking as an 'infrequent adviser' on here, just set up a PayPal account Gordon and I'll happily chip in !

Ah...ok. if these same pots. have worked OK before and they are identical to the originals then it must be something else then !

-You may be surprised though how if suppliers think you are just using them for 'something fairly basic' they may well often supply you with what is convenient for them - and 'presumed' to be an equivalent (eg. CW pots rather than CCW pots which does not matter that much for most circuits but will obviously not work in a positional servo situation etc)

Interesting - but excuse me Marty while I ask some more stupid questions (but which I have been known to do before...)

Have you used these same Piher pots successfully before ? Are you sure they have the same mechanical/electrical characteristics as the originals ? (eg. a 240 degrees turn is max. to min. value etc) Definitely LINEAR and not LOG or ANALOG ?

http://www.piher-nacesa.com/pdf/14-PT15v03.pdf

'Trimmer Pots' are just that (in that they allow you - manually- to make small(ish) changes to a circuit) rather than being mechanically linked (eg. to a flap etc) for 'circuit feedback/servo' purposes and so whatever the replacements are they will need to be identical to work properly.

Not sure what type of pots we use there Marty (and you may have to dismantle one to find out for sure) but if they are the carbon track type in particular they can develop 'flat' spots (ie. in/on the area/track they are used the most)...

When you are checking the resistance across the range of the pot (ie. to ensure it is a smooth/steady change in resistance) it may be quite hard to spot a flat with a digital multimeter: Try an analogue meter instead; Not saying it will tell you for sure if the pots are iffy but it can't hurt to try.

(I have encountered this issue myself checking the likes of flappy air flow meters, fuel tank senders etc; ie. Seems 'OK' with a digital meter, only see the flat/worn tracks for sure with an analogue one. It can happen with wirewound pots too but depends on their construction).

Finally are these pots. linear ones ? - The other issue I have noted is folks sometimes test/replace LINEAR ones with LOG ones of the same value...

Nahh - he is way too wimpy to join for real, unless it IS him - and he has come to say he is 'very sorry' before we all 'grass him up' ?!

Tell you what OB, I'm picturing a Clint Eastwood western (in fact most of them) where the chief baddy gets his come-upance after he has said "who are you ?"

" What's that Toad - when a man with a grease-gun meets a man with a torque wrench the man with the grease-gun is dead slippery ?"
No ? how about:
" Go Ahead punk - make my day - Search for Rave".....

What's that Iconoclast ? You were blacklisted for posting up information about the colour black ??

It is amazing that for someone who seems to enjoy repeating 'Read Rave' / 'Search' Toad has yet to be found out as a "off-topic irrelevant idiot" !
Maybe he has some photos of the owners in compromising situations or something.... ? Only that could explain his longevity on RRnet....

Seriously I think he 'gets off' by finding the tiniest reasons for banning folks: Result of a tough childhood probably (?) Needs Therapy !

Post those photos up here instead: I was looking at colour charts recently and was amazed at how many shades/variants of black there are....

Do the swearing first - oh you already did ! Yes, steel pin, alloy plates, salt/water etc sticks it in there pretty good.... I used a Dremel to flat the end of the pin off then a thin/hard drift to move it in sightly, then repeated the process on the other side. At least the old springs are trash so what's left of the pins can stay in there forever... and the newer designs are plastic not alloy bases.

I would vote for an iffy Driver Pack !

You mean this one ?:-

Well maybe even he just got sick of TOAD too ?

Marty's definitely your best option with this Stokes90:He really knows all about this stuff and frankly i would not trust even a local 'LR Specialist' who would just truck it away to a garage and charge ££00s probably to tell you it needed ££00s to put right !!

You could try moving it somewhere in case there is some huge RF signal where it is at present (although if you ask in the shops/businesses nearby they may tell you 'this has happened before with some other cars' (maybe)

You can read through all this too (if you did not already) but there are just too many variables and variants for a simple remote diagnosis: http://www.rangerovers.net/repairdetails/becm/alarm.html

It is no consolation but yes I have been through this whole PITA myself (like many of us)

In the world of (so-called) Data Protection this is basically nonsense of course: http://www.tomtom.com/page/facts

So customers voluntarily 'opted in' so TomTom and Co. could make some money from speeding .... really ?

Wait .....the collected data is anonymous - so that's Ok then; Only other motorists suffer... and so their data can be used against us (and so on)

Yes, Apple and Co. could/can do similar of course: Waiting to get a text message from the cops telling me my iPhone/movements/speed/etc were monitored and so I should report to the local nick immediately....

Have to add here that sometimes when I am poking about in the boots of old(er) cars i find 'mystery looms' too; Often for Car Phones (when these were the size of a briefcase) and often it is also very difficult to know what they did and where they go (and whether they can be used for something else etc) and so in a way it was good of LR to provide that TrafficMaster label...... maybe

As for DVD-Based in-dash SatNav systems yes, many manufacturers were (and still are) convinced that folks will pay £££ for updates. In reality we should just be able to connect them via Wi-Fi etc and update them via our home networks (but where all their revenue in that ?)

Best guess OB is these units used GPRS originally and then switched to GPS. Back then GPS was no so accurate as it is now (and frankly GPRS was quite vague too hence the later DGPRS). In other words some car manufacturers probably tried to accommodate (a number of) vehicle-location and mapping technologies (and then they all went GPS eventually of course). As you may know the (external) antennas tended to be multi-function/frequency 'hybrids' too, with lots that were GSM/GPRS and GPS etc.

The irritating thing is many car manuals don't track such changes and may be simply 'generics' (and parts of my P38 manual are a good example of that, too).

The most interesting issue is how a ten-year-old £2K in-built GPS is now about £40 (for a near-equivalent aftermarket option).... and I wonder how many screens for these ££ SavNavs which went bad then just became a place to put your Tom-Tom sucker on ?! The other main idea of inbuilt stuff is to stop it being stolen but I will not pay £2K for that particular 'feature' either ! I know P38 in-built SatNavs have that dire/quirky powering-up (self-destruct) 'feature' too of course (aka bad design)....

Trafficmaster could use voice or screen: Thus guessing that cable was for GPRS use as in:-

" Trafficmaster's SmartNav package used kit fitted in users' cars and a call/data centre. The car was linked to TrafficMaster by GPRS (and a voice channel for the driver). Drivers could call in to TrafficMaster to ask for a route plan from the call centre; the call centre had real-time traffic data as well as ordinary mapping and locations.

Instructions were delivered by a dashboard speaker or optional screen. The car system had GPS satellite nav, and told TrafficMaster where it went in real time. "

Note: Around the time (c.2005) there were concerns that it would allow 'others' (eg. the Govt.) to track users, leading to the 'unpopularity' of the system....
