DB20G radioditty

[WSBZ498]

Hey all, been asking lots of questions, again for the Radioditty DB20. There a way the sub channel gets muted when the main channel is getting used, I can’t seem to find the setting or figure out how to.

I have a question for the Radioddity DB20G (not a typo).  I tried to tune it to 146.520, the National Calling Frequency, VFO mode, entering the frequency from the microphone buttons (14652000 ).

It wouldn't accept it.  It "adjusted" the frequency to 146.52500.  

Using the Up and Down buttons I can step between 146.5000 to 146.52500, so it appears the step size is 25 KHz.  I have Step size set to 12.5 KHz everywhere I found it mentioned.

With the CPS I was able to program 146.520, but not from the front panel/microphone.  What am I doing wrong?   

@WRYS709 - I'm counting on you.  You've dug into this radio more than anyone else still around.

Try lowering the step size.

I have it set to 12.5 everywhere. That’s the lowest it goes, as far as I can tell. But if you know where it can be set lower, or even to 20k, please let me know.

I think you're looking at Channel Spacing (which is, for whatever reason, bandwidth). 12.5 is narrow, 25K is wide.

Step size I think can go down to 2.5K.

Looks to be Menu 6 on the radio:

Turn it off. Fun + 8, unless they have a typo.

Your last question was for the Radioddity DB25-G; is this request a typo?

Try lowering the step size.

[SteveShannon]

Thanks, Amaff!! I’ll try that.

This is the one that I think will be the solution.  I'm on my way to try it right now. Thanks again, Amaff.

 

That was it.  Before I had been adjusting the Step Size down in the channel list.  The menu item #6 isn't even visible if you're not in VFO mode. My Step Size had been set to 25KHz.  I have set it to 5KHz now.

Awesome, glad that's all it was

I had a weird issue on mine last week listening in on a few VHF repeaters.

We were at Yellowstone and I had some of the park ranger repeater frequencies programmed to listen in on (166.375, 165.5875, 166.875, 172.500).

About half the time, after a transmission the squelch on the radio would hang open (hooray deafening static!) until I cycled the MONI button on the radio, which would shut it up.
The other half of the time it would work normally with a brief burst of static after a transmission as you'd expect on a repeater output.
I listen in on VHF repeaters near home pretty regularly and have never had this issue, so it doesn't SEEM like it would be the radio, but it happened on multiple repeaters in different parts of the park.

I turned the squelch up, I turned it down, I turned it medium, but nothing seemed to correct it.

My working theory is they're using commercial gear which is transmitting a data burst after the operator keys off and that was screwing with this 100% analog radio? But that it wouldn't stop on its own (like, if I turned the volume down it would stay for minutes if it hung and no one else spoke) was very odd.

Anyone seen (...heard...) this before and / or have a fix?

In spite of the fact that I hate this format of votes vs. chronologically sorted; I will give this some thought.

In the meantime, I will ask you on your other post to identify the items in your Yellowstone Go-Box; thank you!

You get to decide whether you see chronological or vote-based sorting:
