Hello, I have an Icom UHF installed in my vehicle and its fine but when the ignition is switched off the Icom is also switched off, which is great, but it stays off when the ignition is switched back on The wiring is very simple, positive and negative and no memory wire. Does anyone know if these can be persuaded to come back on with the ignition? There is nothing in the manual

Cheers Jim

I think you answered your own question.

Hmmnn... maybe, but my stereo has no memory wire and it still returns to the same state that it was when the ignition was switched on.
ie radio on, engine running - switch off ingnition - radio stops- switch on ignition- radio back on. Not the same for the Icom. Icom stays off

Your car stereo probably has something inside it like 99.9999% of others that assists it in staying on when the key is turned back on.

I have the same radio I think (IC400PRO) and when it was initially installed it was same as yours. Off with the ignition and you then have to manually turn it back on.

I went back and got them to wire it direct to the battery. Now it is on all the time which is MUCH more convenient. When going on a day trip it is amazing how many times you actually stop and start and cycle the ignition. With the radio hooked into ignition circuit it became really annoying to keep turning it on.

You may be able to get it to turn on with the ignition but even this would annoy me as often you want the radio on when at a campground so you can hear ithers returning to camp and so on.

The radio only _Affordable_Storage_Drawers.aspx something less than 300Ma when on standby so there is very little risk of flattening battery with radion on all the time. It would need to be on for at least a week to make a dent in an avaerage 55 amp hour battery.

My advice is to just go with a fused direct connection to your battery or even better to second battery. Radio can run all the time or just for your trips away.

Only issue with direct to battery, is remembering to turn it off.

The 400 has a programmable feature that allows the radio to power up when power is applied, this has to be enabled along with a direct battery connection.

From what I understand it has to be done from the PC. If you don't have the cable and program take it to a dealer. I don't have a 400, I read this info on the yahoo 400 group sometime ago.

Hi,
I have the IC400pro with the programming software. Mine is wired to the second battery so can be left on permanently, with no impact on the main battery's ability to start the car.
The radio can be set (without the software) to turn the transceiver power OFF automatically after 2 hours when no key operations are performed or receiving no signal. This is done by going into set mode on the radio and working through the menu.
I quickly checked the software and cannot see how you would set it to come on with the car if it was wired as a conventional accessory. I find when travelling it is quite good to leave the radio on when stopped.
Cheers
Andrew

Ok, you made me go and track this down..hehe :)

Apparently it is the IGSW parameter

From the 400pro software:

IGSW
- When the ignition switch is turned ON, the transceiver
power turned ON automatically

Agreed - the setting is certainly there in the software (which I missed!).

I checked my mates configuration, he has this set, with the radio wired to the accessories on the ignition switch, but the radio does not come on when the car is started. Makes me think there is something else required to make it happen - but I've got no idea what.

Cheers
Andrew
