didnt they have several variants of that radio? Backpack, ammo can, mobile, etc? The battery back is what made them heavy as in the ammo can and mobile version they were realitivitly small

I have not had any problems with my Q10H yet. But I have had other brands of radios act up. though usually just reloading stuff fixed them. I've had Icom and Yaesu radios have glitches too.

Make sure to fill us in..

I hated when I had to carry the PRC-77. At least I did not have to carry the PRC-77 at the same time carrying the M60 machine gun. The only SINCGARS radios I dealt with were vehicle mounted. They were heavy enough trying to carry from the shop to the vehicles for installation.

Just added that to my cart. I'm gonna test it next week.

I've looked at the spec's for the man-pack radio itself. https://en.wikipedia.org/wiki/AN/PRC-77_Portable_Transceiver At 1.5 to 2 watts for the size at the time seems crazy now days. Just think what a modem commercial, not military, grade P25 HT can do , 5 watts and with AES256 encryption. It would fit in a uniform shirt pocket. I also checked the spec's on the old WWII handie-talkies. I was shocked to see they only did 360 milliwatts! Remember that while watching those old B/W WWII movies. https://en.wikipedia.org/wiki/SCR-536

Okay, I reported your issue also.

I have the same issue & reset password & followed instructions. Still same issue. I am told I have to create an account in forum but it won't let me saying I already have an account.

Yup..

Hello, this is whats missing Amazon.com: ZEZEFUFU Two-Way Relay Walkie Talkie Repeater Box RX/TX for Baofeng UV-5R Accessories 5MHz U-V V-U Cross Band Walkie Talkie Repeater : Electronics

Okay, check your email to see if you received a password change link. Follow it, bla, bla, bla.

I am thinking you need to swap radios on the duplexer ports. Like, I think they are labeled backwards. It would make sense that the case of the HT is letting enough RF leak in to trigger a receive light, but there is not enough of a signal to create usable audio output to trigger the vox operation. If its not labeled wrong and it is wired correctly, you could just be washing out the systems due to being to close to each other and too close with the test handheld. I have seen some HTs so sensitive to RFI from other HTs, that we had to separate them by 75 to 100 yards before the RFI and desense was small enough for the radios to work correctly.

I haven’t tried it. Won’t be able to test it til Friday but definitely worth the attempt. Thanks for the tip.

So this is a full spectrum tuned duplexer. Says 550-725 on the label. So have you tried this on other frequencies? How about separating the RX and TX HTs. Put on of them in a metal box to try to isolate it. Maybe the common antenna is desensing the HTs

@marcspaz Yes, using cable exactly as you describe with Vox. Yes, it seems to work without going to the duplexer using whip antennas. There’s some background noise but I figure that’s due to the proximity of the antennas. This is what happens. As a separate troubleshooting effort, I moved the common antenna away when the HTs were connected at one point. Still nothing. It seems to be on the receiving radios output or the transmitting radios input. But the connection cable works fine without the duplexer so I’m leaning more to duplexer issue. I’m open to suggestions.

I need to ask some questions... You are using a cable to go from the receiver audio out to the mic audio in, and set to vox? Correct? If you simply remove the antenna cables from the duplexer, everything works (as well as to be expected without a duplexer, anyway)? When you hook up the duplexer, the receiver receives a signal, gets a green light, but the transmit radio doesn't go into transmit mode, even though vox works fine without the duplexer? Or does the transmit light/display indicate that the transmitter is actually transmitting, but there is just no output from the duplexer?

Thanks! I found it.

Tried it again with another set of radios. Works ok enough without the duplexer (less desense). But, it still doesn’t transmit from the speaker of the receive to the mic of the transmit.

I think both radios need to be the same brand or use the same compander tech AND compander has to be enabled on all radios wishing to benefit from the tech. Otherwise, it sounds worse instead of better. It's been awhile since I read about it and I don't know anyone personally who uses it due to the compatibility issues.

I would implement a controller, Surecomm will have something that works with HT's

Thanks. I'm still learning. I think I'll avoid compander unless issues arise. And in that case it may or may not do any good.

I thought about that too, but thankfully a reset fixed it. I don't think a reset will help with kill or stun.

My first thought is if the radio received a remote stun or kill. Page 108, 109 in the manual. Though random glitch is probably more likely.

The new fangled radios are all computers now. And just as any computer might need the occasional reboot so do radios. Having to do the reset is just a step farther. I had to do it on one of my Wouxun radios that was acting weird. Fixed it up and I just hooked it up to the computer and reflashed my channels back into it. 5 minutes and done. But this would be a serious problem if it was an emergency. Good old fashion radio guts with no computer can have an advantage sometimes. Same goes with automobiles.
