my prayers are with the people of Iran and they are successful in getting their total freedom back they once enjoed.

No, my call is Whiskey Romeo XRay India 733

Well, we can hope…. It worked so well in Afghanistan, Iraq, Vietnam, etc. Syria was different because the U.S. wasn’t overtly involved. It stands a good chance of succeeding.

The only hope, and for the people of Iran and their future, is they stand up against their leaders.. Isreal and the United States will help this effort if the people of Iran are serious in demanding this change and their is evidence their leaders are doing bad things to their people. I wouldn't rule out the United States helping the People of Iran taking out their religious leaders.. In fact i would hope we do and only to liberate Iran

I doubt that what’s left of their leadership will change. Nor has the U.S. shown an interest in attacking their religious leaders (and they probably shouldn’t).

You need to clear your cache. No, I’m wrong. Although it isn’t jumbled for me, the home page is asking me to create a new password again. I’ll report it again.

My first Duplexer from BuyTwoWay covered the entire GMRS Band and my repeater then was on Ch 22. I had a terrible experience with it, ended up buying a tuned dublexer tuned for Ch 18 and moved there.. Been working great since.. I sent the original duplexer back to BuyTwoWay and had them tune for CH 18 to use for my portable repeater which i mounted to the outside of a FAT 50 Ammo Can. Since this portable set up gets moved around a lot, i'm always concerned that the duplexer will get knocked off tune, but going to almost 3 years now its holding tight on Ch 18.. I did try to tune it myself as Marc did, but didn't have such luck or patience.

any humanitarian efforts in Iran at this point would be fruitless. Considering their government wont allow any help from the West in that effort, the only hlep they are seeking at this point is further destroy Israel. Humanitarian help will be coming to Iran but its weeks away and only after their leadership is gone...

Humanitarian efforts are just that and should be given without political consideration. It's not the people of the country that is the problem, it's their government. I work with an Iranian and he has told me stories of what goes on over there. Trust me, most people over there really don't believe in what they have to live under. If cheap GMRS radios can help the cause it shouldn't matter which country assists in humanitarian aid.

Exactly. They can get bulk discounts, even free Baofeng radios since it's a humanitarian crisis.

11:00 AM EDST Sunday, Home page still a jumbled mess. I cannot access repeater listing but oddly still can access Forums.

Here is a simple to understand description of IP ratings: https://www.iec.ch/ip-ratings The first numeral refers to the protection against solid objects and is rated on a scale from 0 (no protection) to 6 (no ingress of dust). The second numeral rates the enclosure’s protection against liquids and uses a scale from 0 (no protection) to 9 (high-pressure hot water from different angles).

I started playing with a Baufang UV5R (before they locked them) in the HAM bands. Got bored with the HAM world and programed it to the GMRS side and thats when i began having fun with radio... My first GMRS radio (and favorite) was a Wouxun KG935 HT. I still dabble with HAM but for the most part i enjoy the GMRS side. I never did try a UV5G but did program one of my UV5R to GMRS only. Since these radios are all locked now i would recomend a UV5G or a Wouxun GMRS only radio, they have a few versions now..

The 905G is not CHIRP capable although the wouxun software works fine, but if you plan on getting more radios and wish to copy paste between, the CHIRP is your friend there. The 805 is CHIRP capable. .The cable you want is readily available almost anywhere, Amazon or buytwowayradios.com those will work with the 935,905,805 or almost any other radio or radio brand with a std k1 connector. I would suggest buying not from Amazon as Amazon is rife with crappy knockoffs of this type of equipment that uses perhaps questionable driver or just plain won't work. 805 is IP55, 905 is IP66, 935's are IP66. 55 means dust protected and can resist water jets. 66 means dust tite and can resist powerful water jets. I have a yeseau that is IP55 and I've dropped it in a stream, it was not affected. I've also had a 935 fall off my sxs in my back 40 and lay in a puddle for a month, been run over a few times before I found it, it was not affected at all. So anything IP55 or above would be just fine for heavy outdoor use in snow, rain.

@marcspaz thank you for the detailed information on tuning the duplexer. We are lucky in that one of our members retired from Sound Solutions and he still has access to all of their equipment. He has tuned all of our duplexers.

Given the present situation, I doubt that the US State Department would ever authorize any such gesture of aid to any country that is hostile to the United States or it's allies.

Very true, but they are very friendly with China.

I doubt anyone in Iran would ever accept any wireless devices from any country allied with Israel.

I use the UV-9R PRO on our ranch & range and they work great. They work with chirp also.

I think the KG-935G plus was claimed to be IP 66 or 67, and I'm not sure what the IP ratings were for the 805 & 905 models.

Send them that bug report.

It's a Smith Chart SWR Circle. It's a circle that is drawn centered at the origin frequency, passing through the plotted impedance point. This circle represents a constant SWR through the range. The value where the SWR circle intersects the positive real axis (right side) of the chart indicates the SWR. The closer the red dot is to one of the lines radiating from the right side, the closer to 1:1 the SWR is on that frequency. I tried the TinyVNA and it did not work. It was way off... very inaccurate. A friend of mine (who is a retired RF engineer) uses a SAA-2N VNA when he is in the field. He has great results with it, which is why I went with that specific VNA. It's "good enough" that I would not encourage people who are doing this as a mild hobby to buy a commercial Signal Analyzer. If professionals are using it, the SAA-2N VNA is good enough for me. I have not compared mine to a commercial grade SA, but I have tuned 5 duplexers (UHF and Commercial VHF) with the SAA-2N VNA since I bought it and have had amazing results. With a 2m repeater only having a 600KHz offset, accuracy is extremely critical. My 2m repeater is covering over 8 miles with 5w handheld radios and well over 25 miles with 50w mobiles, and the antenna is only 100' above the ground, 200 feet above average terrain. Those numbers are both further than the theoretical/calculated RF LOS. So, I personally have confidence in the SAA-2N VNA.

Without knowing what frequencies are being used locally there I think that would be a dumb idea. There are warnings all the time against taking FRS, same frequencies as GMRS, radios on foreign vacations since the frequencies could be used by local fire, police etc. services.

I've held off spending money on one of the tiny VNA's since I'm not really convinced they have the dynamic range claimed. I would like to see some verification of the spec's testing against a know high quality lab bench VNA. For tuning these cavity filters you really need the high dynamic range to be sure you have all of the cavities aliened.

You're as bad as me for staying up late. LOL Ya, I saw how they painted the screws. Shot them from one side to help lock them in I suspect. Didn't think about how that might impact re-tuning though. Thanks for the tour. Do you know how to read the circular graph? The curly cue lines are intriguing, really curious how they are read.
