Stryker slimmed down SR-447 HPC2
- Thread starter BBB
- Start date
Dont have pictures but on mine they are written on the board beside the resistors R297 and R299
Just ordered a new Stryker SR-447HPC2. Should have it in next week. I declined the peak and tune.
Hopefully, I will be able to convert this radio with Stryker software. I did not buy the Stryker "special cable". I did buy a USB 2.0 A male to USB 2.0 Mini-B from Amazon. I think that's the right cable.
Amazon product ASIN B00NH11N5A

What’s the final output power when it’s been Aligned I like the Compact size of this Radio Appeals to truck drivers
as it’s compact size

When there’s a good installation (upgrades) in a big truck, that’s one of THE best-sounding radios on AM it’s possible to operate from a big truck.
One doesn’t need to ask the brand.

Got the Stryker SR-447HPC2 yesterday.
Reckon I will need the Stryker "special cable" because it has a serial port converter chip. No way to turn that annoying beep off. Friend of mine is going to let me borrow his cable.

The Stryker cable I borrowed worked just fine. Windows 10 created the communication port automatically. Finally got the annoying beep off!
Like Eldorado828 posted earlier, resistor 297 and 299 need to be removed for conversion. I did not de-solder the resistors. I cut them will a small pair of snips.

Just clip these 2 resistors in picture above and hit the D band and 11 meters is there
Just got one of these, finally put it on the bench. Did a quick function check to make sure it wasn't DOA, then clipped the resistors. The stock mic is decent, but I like the sound of the Astatic 636 better. I tried to adjust the ALC with my scope while talking into the mic. Couldn't quite tell what was max, so I used a 1khz tone on my phone instead. I tried a couple of power mics, which really made a difference. If this was a Cobra of a Galaxy, I could change the negative feedback for the audio amp to make the 636 the equivalent of a power mic. The tiny surface mount devices in this radio make this impossible for me. I settled on the K-PO NM532 turned about a quarter of the way up. Easily hitting 75w peak from any dead key setting, the radio will do 120% modulation and will hit 150% if you try. Amazingly, no flat tops or box cars. This is what really separates it from the other radios being made today.
Heck yeah, it appeared it hasn't changed then. They're loud talking little radios and for the price can't be beat by many other AM exports. I use a telex turner rk56 and sounds great imo. My only gripe is the small controls but it's because of my fat vienna fingers.
Thanks @Shadetree Mechanic now I'm going to swap mine back into the truck lol. Always gets compliments on the big road!
