Hi, See: https://www.worldwidedx.com/threads/and-now-for-something-completely-stupid-the-tweety-bird-noise-toy.270184/

In the case that you're in need for more switches. If you can indeed repurpose that 9/19 switch then perhaps you can do something like short press is function X and long press is function Y?

A "double press" on the rotary encoder like a double click with a mouse perhaps? Agreed on a channel 9/19 switch to be completely useless and a good candidate for being repurposed.

Never a fan of adding new holes in a chassis for accomodating new switches. It's difficult to see, but can't you swap out a potmeter with a potmeter that has a switch? Or perhaps the current encoder does not have a push button function and you can replace it with one that has?

I'm slightly confused, are you talking about other websites? As I just tried to download a few of those files again and they are still OK from the looks of it. FWIW, I did download them all earlier and can provide them if they do go missing. Also note that this site is already archived at...

Probably should have linked the project I tinkered with as it is actually open source (both hardware as well as software). http://www.hvde.nl/electronica/tx/4m/arduino/CBto4_3.1_nl.shtm It's in Dutch, so you'll have to use a translation option. Obviously the design doesn't apply to what you're...

Yes.. please go on, keep us in the loop. I've done a bit of arduino stuff with a DDS in the past, so can follow it somewhat. Haven't peeked on serial data with a scope though. Don't have a bearcat here, nor are they easy to get by down here in my neck of the woods. But as you say, the same...

The schematic can be found here: http://78roger.free.fr/crt/hercule_turbo.htm at the end of the service manual that is linked down there.

Always enjoyed reading his posts here at the forum. He had some great stories in him and did know how-to tell them. Wish a lot of strength to his loved ones. RIP Unit 399.

I just send him an email on your behalf. Best of luck!

Yip.. that's how I used to measure the frequency, works great.

I found this video that Brandon linked earlier very helpful in explaining the digital scope specifications. https://www.worldwidedx.com/threads/digital-oscilloscope-users.270715/

Hi, I've never measured high output like that myself yet, but with that out of the way... Before I got my wonderful Spinner 40dB attenuator that can handle 400 Watt, I did build myself a RF Power Tap and that works pretty well. (I tested it with low power only) See this pdf...

lol, even that doesnt' help as the stack of radios to work on still grows faster than they get repaired.

That looks brilliant! Wish you have a great time enjoying this radio.

Just had a nice chat with CT4005, Chris from Northhampton UK on 27.325 FM with 100 Watt using my Anytone Q5N2. He used a Sirio 4 elements and came in booming up to 60dB. Quite unusual this time of the year and that at 6pm when it's already dark. Very nice.

Correct. Any of the RM amps that ends on "03" uses MOSFETs.

That's pretty much impossible to answer without knowing the details of the transmitters and receivers. This is why I mentioned the music shop as they could probably give you proper advice on what product would suit your needs. It certainly is possible to get it to work.

Personally I would try a shop for musical instruments. Musicians nowadays also use a lot of wireless setups because it is so much easier. I'm sure that there's also products that specialise on museums etc.. Eg. for people walking around with a headphone through the museum and get an audio tour...

Hi, So you want to put 6 FM transmitters that operate in the frequency of 76 to 108 MHz putting out 7 watt on a small telescopic antenna all within a small space. It's a bit hard to say if it will or won't work. The first thing to remark is that I don't think that your installation is legal...
