I just fixed a dead FC on my RCI-2980 with the help of your video, Thanks a million. Mine had a defective regulator and the wire trick really killed all the noise. Great Video!
Good point on the cap voltages. I am going to use that tip on the next radio i recap. Alternator voltage is 14 to 15 in most of our trucks. Any 16v cap on supply voltage i will definitely go up if i can get the next higher voltage with the dame diameter. Thanks for the tip.
great video Mike. cool advice on the counter module. that wire trick is awesome! on the little 47 ohm resistor, if you are going to solder one end to the 7805, and stick a component lead up through the board anyway; couldn't you just use a standard 1/4 watt resistor in that location? yes, a bit ugly, but would there really be any clearance issues? thanks
Do you know if the magnum S3 frequency counter jack should only have 4 wires connected to board I looked at mine and the yellow and orange wires are not connected to board is that normal? BTW how's the electronic course coming along I'm setting up my patron account ow so I can donate to the cause I'm really lookin forward to it
Greetings! I have a Galaxy DX 88HL that I bought back in 1993 and the frequency counter just stopped working. Any suggestions on how to find a replacement display, or can I send it to you for repair? Thank you!
Hello Mike my Galaxy 99 frequency counter goes berserk every now and again, no one seems to know why. Also did you ever hear of putting Motorola finals in an 88 or 99 Galaxy? Good video, thanks
To completely remove the frequency counter hum there is a brown wire on one of the plugs on the board, I can't remember which plug at the moment. Add a .1uf 250V 10% metallized polyester film capacitor from that wire to ground. The hum will be 100% removed.
If you change the counters resistor value to a lower value, it will reduce its power dissipation and may allow it to be ok, it will be there to act as a fuse, they should of just used a fuse.
It's kind of ironic that the counter board uses a TO-220 regulator and the tiny dropping resistor (physical size) that basically has to absorb the other ~8V of the supply voltage; for something like that I would have expected the regulator to be smaller (or vice versa).
+Dino Papas LOL, you never heard me claim they made good radios. Definitely one of those things you look at and have to wonder what the heck were they thinking.
+Scott Todd The counter module itself is humming? Or do you mean you hear something out of the speaker. Noise out of the speaker, expect that. They are poorly designed and have a lot of digital noise that leaks into the receiver.
Mike !!!! Please read my emails i've sent, Trying to get some questions answered, to get my radios up there to get taken care of. Thank you in advance, Mattb

I sure appreciate your videos Mike. Wish you would start making some more.

Thank you Mike, your a great teacher and tech. Always enjoy your video's. Thanks for sharing and teaching! Joel
Do you have a preference between RUBYCON and NICHICON capacitors?
Mike, good morning. How does one get a hold of you for a repair. Thanks Joel
Hi Mike , I have a Texas Ranger FC390 that reads correctly on lsb but fm and usb read way different . Any ideas what could be wrong with the counter ?
Good 👏👏👏👏
Hey buddy I have a dx 66 v that the frequency counter starts going up by it self

I am looking for a new one or used board like this that works. If anyone knows where I can get one please let me know

Hey mike, how do I contact you to get my radio repaired?
If you change the counters resistor value to a lower value, it will reduce its power dissipation and may allow it to be ok, it will be there to act as a fuse, they should of just used a fuse.
And it will shift more of the dissipation to the regulator.

i have that radio waiting for repair
what happens when you turn your counter on and it hums ?
+Scott Todd

when I turn the radio on it sound great but when I push the button I hear a buzzing sound
and how do I get a hold of ya

Shoot me a email. Just add @gmail.com to my CZcams user ID.
What's up with the coke nail?
What do you think?
Snifffff.
Mike !!!! Please read my emails i've sent, Trying to get some questions answered, to get my radios up there to get taken care of.
Thank you in advance,

All im gwtting outta my counter is a decimal..lol!??
Five seconds into the video before the giggles. Stop it!
