Hello to all Just a follow up to the posting of full duplex handhelds Came across this ht,that a local ham ordered He was not sure if it was full duplex or not I will see if I can download a manual to see Just for a point of interest. I once had a VHF of a similar ht didn't work to good in the ham band And not sure if theses are type approved or FCC approved just a little head scratched for all of you out there Howard VE4ISP
A couple or three years ago there was an influx of h/t's into the UK via e-bay with origins in China - I believe they were marketed under the name JingTong (I kid you not)
If I recall correctly, they were so bad and caused so much interference that eventually the Regulatory Authority stepped in and ordered a ban on the sale of these things.
I was going to point out that they also did not have the CE mark (meaning they were not type approved in Europe) but to be honest that really does not make a jot of difference - anything can come in the UK, its only when it causes so much of a problem and enough people kick up a stink that matters are retrospectively actioned by which time its too little, too late!
You just have to love "light touch" regulation!
But I am with Clint here. Steer well clear.

I actually have one of the JT-308s, and found it to be not too bad. It's a bit deaf and it has not got the cleanest output but there are no particular nasties in the output. A VX-7 is worse!

I have one also. Biggest problem I found was that when I enabled CTCSS, it put this loud rumble onto the audio. Sounded like I was mobile. Certainly wasn't a clean CTCSS tone.

The tone may well have been clean but was certainly much too loud. There's usually a level pot you can adjust.

I have to admit, I didn't try CTCSS because my local 70cm repeater doesn't use it. Sounds like something to check out over the weekend...
