I'm your Huckleberry.

Went to get one the other day, Can't order now till June.

I don't, but a few years ago there was some official at FCC that claimed using a radio that could transmit out of the allowed frequency bands just by using VFO was a violation. I don't remember the guy's name. There was a lot of discussion/argument at the time and I never heard of any resolution. I also never had a problem with out of band TX.

I've done exactly this. It was to demo real-world line loss at example frequencies. I'll share a link if you or anyone else is interested.

FOR OUR MEMBERS, WE ARE ON BROADNET 700 REPEATER. 462.7000 467.7000 PL TONE 82.5 ON TX ONLY

Every mag mount antenna and every NMO kit I've ever seen uses RG58. I'll bet all of you have at least one on one or more of your radios. RG58 is even more lossy than RG8X, so I'm mystified about why your installation is right and mine is wrong. If the dummy load isn't between your ears, tell me something I can use. Be Elmer, not Mr Magoo.

Why do you need to? I’ve never accidentally transmitted out of band on any radio ever. Why is this even a thing? And I do give my radios to noobs, kids, older people ect. No one ever accidentally changed to fbo mode and then transmitted out of band.

I'm going to do some testing with various antenna's on this wouxun this weekend . It's just that little tiny wall on either side of the radio, one by the on/off knob and one on the antenna side that makes me question the fit .

So what is the right cable? "You're doing it wrong" isn't helpful information. It might make you feel superior, but it sure as hell isn't going to save me any heartache or money.

Thanks for your input and the photos you shared, I'm going for the LMR400 equivalent. I only need 40 ft so it should work out for me,it just needs to make one 60º bend through a port in my exterior wall it should be flexible enough for that.

You simply use the correct cable, and RG8x is simply not going to cut it on UHF. Only place RG8x should be used as a compromise cable at 30MHz and below, and that's a stretch. You lost so much power using the stuff it even fooled you into thinking you have an acceptable VSWR, kinda like a dummy load. Just trying to save you heartache and money.

How about duplex? Will it let you set duplex to off ? my bad I just seen you were talking about in VFO mode. So disregard my post !

this is why I'm a fan of VNA's to get a picture of both coax and antenna on a separate scale

I've tried the Nagoya 701G and 771G on my KG-935G and the stock Wouxun antenna performs better. I do see an improvement when using the 771G on my Baofeng UV-5R GMRS radios.

Thank you for the reply I also have a baofeng but it's a uv5G plus and two TD H3's . I'm addicted to these little radios.

Put the SWR meter at the end of the run of cable and before the antenna if possible and you will get a more true reading of the antenna SWR. Coax can introduce as SWR as well so it'll still be higher than what the near antenna reading is.

I have the KG-S88G which is of a similar form and the 701 fits fine. That said the Wouxun stock Antenna I think is better than the 701G. I do use the 701G on a Boafeng UV9G and I think it is a little better than the stock on this radio.

Yes.

I was reprogramming channels on my K5+ using Chirp and could not find a way to block transmit in VFO. Chirp does not allow setting frequency range limits on these radios like it does for others like UV5R. I know about setting Duplex to off for memorized channels but that leaves VFO open. Is there something I'm missing or do I have to just hope Chirp will add the frequency range settings eventually?

It sounds like you're saying there's no point in testing. Any cable that's practical for a vehicle application will be lossy. RG58 is even worse, and that's what pretty much all mag mounts and NMO kits include. Are you suggesting we should use LMR400 for vehicle antennas? Why do you assume the antenna has an SWR of 10:1?

Maybe 2 tests, one at the radio and one with meter at antenna end of cable. Compare the two results.

Alright, smart guy. How do you hook up an antenna without using a cable?

Yep, he built a dummy load with that cable. Silly rabbit.

Hello folks, I have a wouxun KG-S65G among a few other HT's. Does anyone know if either a Nagoya 701G or signal stick 440 will fit this radio? There is a small wall on either side of the radio that is keeping some antenna's from fitting properly. The Smiley's I have will fit but only without the cone and there's a significant gap . My 771g will fit but is longer than I want on this radio. Thanks

Those SWR numbers are not accurate. Keep in mind that SWR is calculated by the following formula: SWR = (Forward Power + Reflected Power) / (Forward Power - Reflected Power) But that requires an accurate measurement of the percentage of the reflected power compared to the original power output. At GMRS frequencies RG-8x converts 44% of the RF output to useless heat before it ever reaches the antenna. So of the maximum of 50 watts transmitted by a GMRS radio only 27 watts reaches the antenna. That’s the Forward Power. Then, if the impedance of the antenna isn’t perfect, some amount of the power is reflected back towards the radio. That’s the Reflected Power. By the time it reaches the radio 44% of the reflected power has been converted to heat. So, let’s say you have an SWR meter right at the radio and let’s also assume that the antenna truly has an SWR of 10.0:2 at 462 MHz. An SWR of 10.0:1 means 67% of the forward power is reflected. That’s a pretty abysmal SWR for any antenna. So for a 50 watt transmitter 33 watts reflects off the feed point of the antenna and back towards the radio. But now let’s introduce attenuation. 50 watts doesn’t really reach the antenna. We’re using RG-8x so only 27 watts reaches the antenna. Two-thirds reflects back towards the radio, so only 9 watts of power is radiated instantly. 18 watts is the reflected power at the feed point but of course 44% of that becomes heat due to attenuation. 56% of 18 watts, or 10.1 watts makes it back to the SWR meter. So the SWR meter sees all 50 watts forward power and only 10.1 watts reflected power. It’s calculation says that is a perceived SWR of about 2.6:1. The point is that lossy coax results incorrect SWR measurements, whether done by a nanoVNA, an expensive bench model Vector Network Analyzer, or the priciest antenna analyzer out there and seeing a lower SWR becomes meaningless.
