If it has an NPCRC mod, look for the wires that will be originally at TP(test point) 1 and 2.

If they are going else where, it might have the NPC mod.

I can't be sure, I forget some of it.

The reference to changing R130 is not correct on a Grant XL , I think. It's R131.

No NPC.

See the purple wire along with the yellow brown and white in front of the large electrolytic radial cap?

That is typically used in the NPC mod.

I think.

There is quite a bit that can be done to that radio, but it is an excellent radio all by itself. The grant xl, grant lt, and cobra 148gtl are all the same radio. It's probably my favorite CB. I'm sure DTB knows how to do it right. If you can figure out what all was done already that will be helpful to whoever looks at it. If I can be of any help with the alignment or other mods, let me know. I have a Grant LT (same thing) and I love that radio.

BTW, you can get the schematic from cbtricks.

From what I can tell the green wire is for the clarifier...

I haven't even put power to this thing yet...haven't had time.

And don't get me wrong, I wouldn't know what to really look for to see what has been mod'd...other than booger solder joints and clipped wires!

I basically want this radio to be stock, with a clear audio and sensitive receive...I've heard good things about the Grant as far as the audio being awesome, one of the main reasons I had to buy one (plus its a SSB radio)

I got a TS 350HDV to run behind it for SSB use, so I don't need it to have every last watt wrung out of it.

The dual clairifier is a very nice touch from the pic's it looks like it's opened for RX/TX . Do you know what the power ratings are on AM and SSB ? Have you hooked her up yet ? Does it seem at least ballpark alighned to you ? closest to center slot will do on the duals (it doesn't have to be perfect , just needs to lock down and stay on freq which those radio do a fine job at) they do like a slight warming concerning SSB all the same. (most do)

I see now where it says you haven't even hooked her up yet. Depending on how the TX/RX was opened up , that baby could have a 20 Khz slider on it , although touchy , it will get the job done nicely. If the radio has a (call it what you want) NPC mod , it would DK 1 to 2 watts and swing 18 to 20 on AM which would be pretty good for your TS350.

The radio could swing it's full power on SSB and the TS350 would handle it just fine. If you can find out what your AM side is doing and as long as your as low as 2 watts on DK , you should be fine. Otherwise , you can just send it off to your favorite tech and have him go through it for you.

Always nice if given tech could have both radio and amplifier when he does his alighning , but I think most would know how to set up ballpark for a TS350. Like Mole said , these are also my all time favorite cb chassies , always known for there great receive sections in them.

I will also agree that not alot needs to be done to these radio to perform well right out of there boxes new. There's really no need to bore these radios out , but guys tend to like what they like no matter what somebody else thinks. It looks like you have a good one Steve , but I also think it might be to your best interest to hook the baby up and give her a work out , the mods on the radio from what I can see are not a hack and whack job , they have been around for a long time.

As always , the best of luck to you and I hope you find some enjoyment out of your new (to you) Grant XL . Peace

No, haven't had it hooked up yet...I'm taking it, and the amp, to DTB (speaking of that, I got to call him and make sure he'll be there). Let him see what's been done and what needs done...

He did my DX959 up really nice, hoping he can make this Grant sound the same.

Whoops! This radio didn't come with a mic, and I noticed it has a five-pin connection...not a standard cobra/uniden 4-pin.

Can a 4-pin (like a Astatic 636L or RK56) be rewired for the five pin???
