Original Stryker....Shawn!

Change R35 from a 0 ohm (thats right, 0) to a 5.6-6.8k ohm.

In other words, remove the JUMPER from R35 and replace it with a resistor.

Scotch is much better!!!!!! :twisted: :shock:

All this drinking,,,,,,,hic hic is the radio fixed yet?

Here's the main one: Change R35 from a 0 ohm (thats right, 0) to a 5.6-6.8k ohm. R35 is a surface-mount near the FM demodiulation IC.

Does it matter if it's the 5.6k or 6.8k??

 

[Strykerradio]

You can use either, the 6.8K will lower the noise floor a little more.

I talked to a person several times that bought a Stryker radio about a week ago and his radio sounded very clear from 6 miles away and he said I sounded loud on my stock Uniden 78 XL on my A-99 on a 20 foot TV antenna pole.

No one said the radio couldn't talk.

I guess what I was getting at was that he could hear my barefoot radio pretty good on channel 19 from 6 miles away. rooooogerrrrrrr

I talk to him today and he said he had the Stryker SR 440. It must be the new one's because he bought it a month ago.

The 440hp seems to hear fine, just has alot of noise coming in with the receiver audio. This is what most complain about.

I did the R35 resistor change. I used a 5.8k ohm R.

Just real quick check to see if the radio still work, found that a weak signal came in noise free. I haven't driven around yet but a quick check from another mobile in the yard hit the receiver just as hard as before with concern to the strength via lbs.

Looks as if this little mod is doing the trick so far and really well if I havent' lost any range.

I will post the picture tomorrow. This can easily be done with a low wattage soldering iron and a reasonably steady hand.

Any update on those pics Shawn??

 

[boomer111]

Well, after driving around all day seems as if not much really changed.

Seems to have helped a bit in that the RF gain need not be turned up as high yet there still is noise coming in with the audio under weaker signal strength.

It didn't make it like the old 148GTL receiver.

Actually DTB only posted part of the modification. The other part consists of a capacitor/resistor modification. I'll get the picture uploaded shortly.

 

[Strykerradio]

Please see the following link for the cap/resistor modification.

Can you post the picture of the completetion of R35

 

[boomer111]

Shawn, is the trace cut separating the two solder legs for the cap? Looks like it just making sure.

Thanks, Dave

 

[Strykerradio]

Yes that trace is cut
