So I did some comparisons across several china radios, specifically a

a UV6R and a UV5. Goal was to make transmit audio some louder.

What I found is that by injecting audio directly into the mic

could achieve > 5khz deviation. But with the same condenser mic, I could
not.

In one case on the WLN, I messed up the condenser mic. I took a

one off a voice recorder playback module that I had lying around, and

replacing on this same radio, where I averaged about 2-3 kc

was now 4-5+ KC.

So what may be happening is that they have poor quality of condenser

and they set gain and deviation for best case being at 5KC. What else
could you do trying to make a $10 radio?

Hello Terry,

"mic gain too low" I guess that means there is a deviation adjustment?

The boothingys are just too low on the deviation and can't do anything
with them so they come up to where they need to be. I have never

that I tried that had enough level, new hams aside, I am going from

I have checked myself.

Like I had said "I hate to suggest to the new hams to buy a radio that
doesn't meet specs and then tell them they can't use them." Sounds

this radio may have promise. Wish I had one to try first. I suppose

I could buy one and if it isn't any good, send it back.

Since nothing is going happen before Monday any way, maybe there

some other reports when people get back from the Dayton Hamvention.

Thank you for your information.

I am not a fan of the cheap Chinese radios by any means. I like my

Motorola, Kenwood, Icom, Yaesu/Vertex commercial and amateur grade

That being said, another local ham and I each have the TYT-UV88,

believe that Explorer radio is just a rebadged version of. We've had
good results with them and they've looked good on a service

fact I was using that UV88 earlier today. Several of us are also using
the Quansheng K6's with Egzumer and F4HWN firmware with very good

The biggest issue I've run across audio-wise with new hams and those

radios are they are too far away from the mic, talking too softly, mic
gain too low, running narrowband on a wideband repeater, or any
combination of those. I helped a newer ham earlier today that had low
audio. After walking him through a few things, he found out that he

the mic gain too low and was on narrowband. He corrected those issues
and was good afterward.
