GRE-XXX Microcontrollers

[3rdHarmonic]

I'm interested in the OEM of the GRE microcontrollers that are in the Realistic Pro 2004\2005\2006

Pro 2004 IC503 GRE-0327
Pro 2005 ??
Pro 2006 IC501 GRE-0918 (Page 68 of the SM it has GRE-0725 on the diagram)

To me it looks NEC 78k series

With all the experience and knowledge the members of this site have, no one knows what these Microcontrollers are?

Forums like these tend to exit as collectors of informatiom rather than providers.

There has been someone on here that would probably know, but not be allowed to say. (Due to an NDA they would have signed.)

You've joined less than a week ago and posted two messages, compared to the hundreds of thousands on here, you don't get an immediate response and you want to criticize the forums and members. Hmmm, good luck with getting a response.

That would've been over 3 decades ago.

Make that three messages,the moderators seem to have not approved the third, maybe you should ask them why

It wasn't criticism i was merely making a point

The fact that messages have to be approved before they are made public goes towards that point.

That the moderators didn't approve a message is a message of its own.

That's exactly right, which goes towards my point

Are you telling me that a modified os456 test utility to allow out of band frequencies would not be a benefit to members?

All new members are moderated. No need for any conspiracy crap. End of discussion.

Maybe no one here knows the answer to your question. You don't, so why is so hard to understand that no one else does either?

Then why wasn't the modified os456 test utility to allow out of band frequencies be made public?
Surely that would be a big benefit to members, wouldn't it?

Since we're ending the conspiracy crap

Maybe no one here knows the answer to your question. You don't, so why is so hard to understand that no one else does either?

If we're following the conspiracy theory, one can argue that if members know, they won't post it now after the Supermoderators comment!

34 year old scanner, no one knows?
To quote RaleighGuy " hundreds of thousands on here", no one knows?

Newbie may be the title of given to new members but it doesn't reflect who they are, you keep thinking that!

I have no doubt in my mind i'll find out what it is, i just thought that i could save myself some time by posting first
But like i said right from the beginning the forum is nothing more than a collector of information rather than a provider, otherwise you would made os456 test utility modified for outbound frequencies available to the public

That was only scratching the surface,it won't be my loss
You're right, now it's end of discussion

What is this os456 utility you speak of and who isn't making it available? I certainly haven't stopped anyone from posting it. If someone has it and chooses to not share it we obviously have no control over that.

Or am I completely missing your point?

 

[cmjonesinc]

It's either some real secret squirrel stuff that we're all being tight-lipped about, or its the ancient optoscan 456 add on for the 2006 (with some sort of hacked expansion I guess?)

OS-456/535 Catalog Page

Funny enough the ole 'search' function yields some results on how to interface it and several of the old download links from here are still alive. Don't know who will find such a niche product to be a 'big benefit' these days but each their own I guess.

Dust off your scan cat gold and pull out those old pentium ii's, we've got airwaves to partol.

That's exactly what it is, why be tight lipped about it since the product is so old?
I posted it thinking someone might have some use for it.

You can still get current pc's (i3/i5/i7/xeon) with serial ports

I had made a post on the radioshack scanner thread tittled "OS456 test utility" i uploaded the winrar file and the post appeared to be waiting for approval
It was made before "Programming Cable for Pro-106 -Pro-197" post, i did a search thinking maybe it was moved to a different area but could not find it

The file is the OptoScan456(tm) CI-V Interface Test Software, Ver 1.0, it has been moddified to accept any frequency you enter, whether the receiver can do it is a different story.
But at least they can test the bandwidth by entering frequencies above and below the accepted values

I found the post in question. Let me investigate why it wasn't approved.

The OS456/535 control boards completely replaces the GRE CPU and directly controls the scanners radio syntheziser. The OS board can tune the radio in the scanner to any frequency in it's frequency ranges. Due the FCC regulations they had to block the cellular frequencies in the OS boards. It is said that the OS456, but don't know about OS536, could be unblocked by entering a password from the PC keyboard.

The OS board can tune the radio in the scanner to any frequency in it's frequency ranges.

The modded utility allows you to enter any frequency regardless of it's frequency range.so you can enter frequencies in the 520-760Mhz range where normally you can't.The scanner has different variations of frequency support depending on country, but that range is not available anywhere

Now that doesn't mean it will work, but if the radio synthesizer was designed to do it and you can receive in that range then i understand why it was not made public

Supports out of band Frequencies Regards 3rd

you can enter frequencies in the 520-760Mhz range where normally you can't.

There are bandpass filters in the scanner, one 280MHz-520MHz and one 760MHz 1300MHz. Trying to receive between 520MHz-760MHz will give different degrees of attenuation depending on where in that band you tune to. When will the scanner switch from the lower to the upper bandpass filter if the CPU haven't got firmware code to handle bandpass filter selection for that 520MHz-760MHz frequency band?

You forgot to quote the rest of it.

It is real simple they can test it and post their results on the thread the moderators have now made public. i'm assuming you're refering to the optiscan cpu cause like you said "completely replaces the GRE CPU and directly controls the scanners radio syntheziser" In that case you can enter 530Mhz and the receiver goes to 230Mhz in that optiscan doesn't even attemp to go their, but i don't ecpect that with the GRE cpu.

Maybe you can tell us what the OEM p/n of GRE-0918 is?

That's all i'm interested in and the reason i started the post
