Car central locking.

Post by MM6VMM »

Took my Openspot out for a drive. Went out to the shops. Left my openspot, router, mobile phone and radio on. So lots of RF within the car. Came back and couldn’t open car door with remote. Even the key couldn’t work. Could hear the central locking click, but not open. Took about five minutes to get it open. Haven’t been able to replicate whilst in the car and obviously not tried to replicate it outside. Is it known for any interference with car central locking?

Car locks usually also operate in the 70cm band. Change your openSPOT's frequency so it won't interfere with your lock.

About 25 years ago some bunch of jokers decided that a new SRD band should be created, they made it within the secondary 430-440MHz amateur allocation because 2 countries at the time only allowed the spot frequency of 433.92MHz. That bunch were part of the EU's (EEC at the time I think) spectrum regulators. As ever the EU didn't care about anything other than facilitating trade and corporate profits.

Unsurprisingly this caused problems, particularly in the UK where the RB repeater 1.6MHz split channels occupied the same part of the band and often desensed the cheap super-regen receivers that were typically used for car central locking receivers. At various times some repeaters were forced off the air because of repeated severe problems despite the SRDs being licensed on an unprotected basis.

If anyone wonders why spectrum coordination is needed, this is a prime example of what happens when changes to allocations are not thought through.

We can talk that the centralized auto Lock is something new(some do not even know what this means XD). Still, with this auto-lock from a distance, cars can be stolen more easily. Some do not trust this type of closure because sometimes if you were further away from the vehicle, you would not react (so you would run out of the car). For new cars with many specifications, the payment fees are high. Not everyone can afford an expensive vehicle, but also with excessive fees. It is the car tax check website, taxes are at a reduced price, and you can do it online. How do you think it's worth it?
