I have a Texas Star DX250 that has been sitting in my closet for about 20 years. I thought I would upgrade the power wires and the change the bulbs to led. the problem is I cant figure out how to remove the push button assembly to get to the bulbs. I also heard that common #74 led bulbs would...

I would perform the NPC-RC modification to wake up the AM modulation. A diode, resistor and a piece of wire will give you a low deadkey with maximum modulation for running into an amplifier

Great job Hawkeye and no i never thought you sounded stupid. Thanks for sharing. Theres nothing more satisfying than fixing it yourself.

Your spectrum analyzer is a great tool. Do you have an O-scope you can beg, borrow, steal? Do you have a schematic of your radio you can share so we all are on the same page? I would take a scope probe and check the audio signal from IC4 pin1 along the FM path till I lost it. or half the...

I tend to agree with M0GVZ. I cant find a schematic for your radio but highlighted the FM path I would be checking for open/shorted components. The audio chip IC4 is good as is the audio output chip IC8 which is just for the speaker/PA. Do you have a RTL-SDR dongle/ SDRPLAY where you can observe...

I love Talkback and want to give a shoutout to NZ8N for his posts on this subject. I recently purchased a couple of these boxes on e-bay He has alot left. just search "cb talkback" on e-bay. these are new old stock and the best i can determine is all mode relay talkback modules for 10 meter and...

That's a nice video showing how easy it is to assemble this antenna. UNIT 314 are you out there? For DIY here's a pdf with dimensions from the web.

Look at the DX Commander antenna. 6 band vertical 40 thru 10 meters in one package for around 5 bills or build your own.

Damnit man, you had my heart pumping thinking you were getting rid of the Autek....

Hello Pierce, This appears to be the NPC-RC modification which stands for Negative Peak Compression- Reduced Carrier..... The diode is missing a 100 ohm resister and the blue wire is volting the final to 12 volts.. This mod when done correctly will allow the radio to operate with a 2 watt...

One Amp will work just fine.. The meter will draw only what it needs to operate..

Its AC to DC

Mine is the original that was sent with the meter when purchased.. Its just a little wallwart made by jameco. 120vac 5.5w input.. output says 9 volts dc @300 ma negative centerpin... I have not measured the actual output voltage but read someplace you can wire it up to your 12 volt...

I agree, that meter is a killer. I also have one I bought new when Autek was making them but its a white face one.. Im still lookin for the black model...

Looking good Tim. Curious did you ever get your Anytone repaired and what was the problem?
