doing the Schottky diode swap on a grant xl

[BOOTY MONSTER]

ive got a uniden grant and i got a new meter and light for it , everything else seems to be clean electrically . no scratchy pots or noisy switches , outside looks like hell though . any how , i want to do the Schottky diode swap on it and then send it to sparkys for a tune and alignment . i found this post by carl and it tells exactly what i need to do , but i cant find all the components it requires to be changed .

http://www.worldwidedx.com/tech-repair/23680-how-perform-2sc2999-schottky-diode-swap.html

it looks like there were once pics there showing the locations , but i guess the host for them is down or gone . does anyone have a pic or link showing where each of the components to be changed are ?

for those of you that have done the schotty swap what differences could you tell between befor and after on your RX ?
any suggestion on where to get the parts ?
also , anyone know where to get a replacement faceplate for it , something that doesnt have "cobra 148" on it ?

thanks

BootyMon - PM me your address and I'll send you one of the 2SC2999'e' - which is a Sanyo part - and is the best part out there (for free!). I bought 60 of these suckers awhile back and have a couple left. The diodes are cheap and plentiful/easy to find - but I don't have any of those left - I'm out.

thanks Rob !

I think if you go back to the thread on the Shottky diodes, it will show the locations for the Cobra 148GTL. If i'm not mistaken, the diodes and transistor replacement should be exactly the same.

I'm gonna open up my Grant XL and compare them myself.
Will get back in a bit...

preacher man sent me a pdf with the pics . i found them on my grant xl and took a pic with the camera and marked them in the pic . thanks again for your kindness Rob

Thanks BootyMon; now I know where my D21 & D22 is at - mine were covered in wax.
I already found the locations of the transistors and D1/D2.
So I can mod mine too.

Well a little late, but it may help ya in the future.... I do have the Sams on the radio....

 

[BOOTY MONSTER]

mr. fatty , your board layout doesnt look the same as mine .
how many different boards are there for the uniden grant ?

 

[MisterFatty]

Four that I'm aware of, Grant, Grant XL Early/Late, and the LT..
They are all close enough once you get familiar with them.

Probably should have used the 148 book but this was handy and for D1,2,21,22 happens to be close enough to easily find them...

uniden grant

the regular uniden grant, not xl, the same?

What ever happened to Booty Monster? how come he shows as a guest with no stats? I enjoyed hi posts and he was active for quite awhile.

What ever happened to Booty Monster

After repeated attempts, and asking many many times for him to stop posting topics that always created problems with other members he was shown the door.
He had many chances to simply refrain from starting it, but it was clear he could not stop.

Hope that answers your question.

Yes it does Jeff and thank you. Hate when that happens!

where can I find schottky kits? I didn't come up with much on google

they are all over ebay.

here is one example:
