All Activity

Glad I could help. POTA is fun. Even when band conditions are bad, it's still fun just to get outside and enjoy yourself. another nice thing about POTA is that it is not a contest and you can work at your on pace. Some want to make as many contacts as possible while others take the time to talk to each person that answers their CQ.

Ok, cool. So it is a game. You've been very helpful, Midwest. I appreciate it!

Yes that is correct. The reason for that is you need at least 10 contacts to activate a park. Plus there is a bonus point for each park to park contact. Here is the official POTA website and rules for POTA activations. https://docs.pota.app

Being old and liking to talk face to face I solved the problem. First a bit of background. Neighbor and her kids survived a home invasion while on 911 waiting for police. The police showed up a couple of hours "after" the invaders left. I helped her and he husband with the use and purchase of that which can't be mentioned here and had an idea. What about a neighborhood "network" where we could check in on those who are elderly or infirm and also allow a call for help from neighbors during emergencies. I went out and talked to my neighbors and some were receptive. So I supplied a few radios to older neighbors, and some bought their own. Nothing official, but it works. No fancy interweb lists or maps, just good old talking with neighbors.

As far as I know, there are two possible but time is needed in getting material and testing completed. People seem to be kinda harsh in these parts from with I have seen as of late. Got to remember, these people are forking out their time and money. I agree with UncleYoda, "I suggest you change the title to "Charleston SC repeater?""

SWR is somewhat important, but tells you nothing about gain or pattern. A dummy load will test nearly perfectly.

I know that none of you will care, but I'm listening to the paid-for repeater tonight and this guy just keyed up, ID'ed himself as new to group, gave his tac number and callsign, and then asked for a radio check and then roger beep. I should mention that the club has a "no roger beep" rule on the repeater. A couple of seconds go by and this other guy keys up and gives him the appropriate feedback and signs off. Original guy keys back up and thanks other dude and then signs off. Roger beep. About ten seconds go by and this third guy comes on, completely unsolicited, and tells the guy to turn of his roger beep, there's no roger beeps allowed. You should know that if you're a member. Turn it off. A few seconds go by and new guy kerchunks the repeater and roger beeps again. I spit water all over my desk laughing. Carry on...

As it turns out, yes, there is a way to do this. Retevis has a solution. I'm truly surprised.

I lived there for awhile. Married a local girl and still have family in the area. It is kind of amazing to me that there isn't one. There's a large HAM community and when Hugo and Matthew hit, they were instrumental in getting help where it was needed. GMRS just has never taken off in the area. My father in law's best friend is a HAM and has a whole outbuilding dedicated to it. He thinks GMRS is a "toy" so, there's that.

I also have a Gen 3 Tacoma. I should take photos. I mounted the mxta26 on an nmo mount attached to a bracket that mounts to the rear of the bed. I ran the coax under the lip of the bed and then through the drivers side pressure vent on the rear of the cab. Then down and under the panels on the door frame to the front of the cab, across under the drivers seat and to the radio. No holes were drilled, and the SWR is 1.01. My bed cover is a multiple section accordion folding type made of aluminum. I've seen a few other installations, but all required drilling holes. While I've done that with my Jeep I'm avoiding it on my other vehicles.

Just for grins I got my power/swr meter out(same one I used to test power output in my videos)and checked the swr(unscientifically)and got anywhere from really good on some frequencies with some antennas to absolutely awful on some frequencies. Some antennas did great on MURS and 2M but totally sucked at 70cm. Many didn't do well at all on 1.25M but were passable on 2M and 70cm. Surprisingly the factory 8" and Abbree 771 were both accaptably on ALL tested frequencies. 2M, MURS, 1.25M, 70cm and GMRS. I guess the factory provided antennas aren't as bad as the old rubber duck antennas they use to provide. I'll probably give the 320a a test to see how it looks before I make up my mind one way or the other.

I'm certainly and self-admittedly new to all of this, but I wasn't even aware that one could test the SWR of a handheld antenna. I'm running a Nagoya NA-771 on my 5 watt HT. I don't have any scientific data, but from a bit of practical testing, I have found that range is much improved over the OEM rubber ducky. I am roughly 40 miles - as the crow flies - from a local repeater and I hear it clear as a bell and have, on two occasions, hit it and gotten a response on that HT with the Nagoya NA-771. I suppose the stars were aligned just right because I have tried several times since and not had success. I was never able to hit it with the rubber ducky on.

I watched an HRCC video last night and he talked about HAMRS. Thanks for the info. You mentioned "park to park." I've overheard Mike on Ham Tube Radio use that language to. The idea being that you aren't talking to a base station in someone's home? Helping activate from another park is preferable than getting a contact from someone at home? Is that the gist?

I appreciate the sentiment, however this ole boy is done summiting. I spent the better part of my early 20's on the Appalachain Trail and a large portion before and after that climbing. I'm more looking for Beaches and Plains on the Air at this point.

I would do a bit more research before sending it back. Checking the match on an HT antenna is a difficult exorcise. Lot's of ways to do it wrong and get crappy results. I've tried it myself and had trouble getting results that looked reasonable. Read the comments about antenna testing and what the guy observed. I did some simple tests using an older MFJ antenna analyzer. Check out the results for the Diamond SRH320A. The results for 2M are particularly weird. WGP - With Ground Plane WOGP - Without Ground plane. Then I ran some SWR sweeps of the SRH320A using my RigExpert AA-1000 antenna analyzer with a special MFJ magnet mount using an SMA connector for HT antennas. The mount was placed on a large 36 inch by 40 inch flat sheet metal sheet for a ground plane. https://mfjenterprises.com/products/mfj-332s?srsltid=AfmBOoq7AleI5bQc6eePGbJ4paGCA-ZK7sBSZWARn6VL0pTjEjIYgUTy https://old.rigexpert.com/products/antenna-analyzers/aa-1000/ Apparently, I assume, something else must be going on to get a good match on 2M when the antenna is on an HT, held in the hand and close to the body, that the testing I did does not duplicate. https://www.diamondantenna.net/srh320a.html HT-Antenna-Testing.pdf HT Antenna Tests Results.pdf Antenna Scan Results (SRH320A 1.25M GP).pdf Antenna Scan Results (SRH320A 2M GP).pdf Antenna Scan Results (SRH320A UHF GP).pdf

This!! Testing the SWR of an HT antenna is impossible without very sofistikated equipment, OTHER than confirming that the antenna is not just a dead-short.

This! Testing the SWR of a handheld radio antenna is either very tricky or useless, depending upon whom you listen to. Performance is what matters.

I'd open it and test it. Results may vary.

RG-8x seems to be pretty good especially if I keep it at 10 feet.

Just watched a review on the 320a, the SWR was horrible especially on the 70cm band. I'll be sending it back without even opening it. Really disappointed that Nagoya would put out a product like this.

The attached files are a couple of the simple Kenwood 2-pin plug, "K1" connector, worthy to look for. I've used the KMC-17 on some CCR radios and got good audio reports. The main issue with used mic's is the cord. The outer material has a tenancy to crack and peel off. If buying used look VERY carefully at the cord condition. KMC-17 Revised.pdf KMC-21.pdf

That makes sense. I have the service manual for the -45. So far can't find one for the -45D. A few of the DMR radio recommended Kenwood mic's had a few extra ceramic cap's installed verses the non DMR recommended models. The really fancy one is the KMC-52D. That one has a full builtin DSP processor core, and it's own programming software. The big pit fall with the various digital voice modes is the CODEC is HIGHLY optimized for voice only. Things like wind noise, sirens etc. will bugger up the conversion from analog to digital. The DSP based speaker mic does all the filtering and noise cancellation in the mic itself before the audio is passed to the radio. By comparison the -45 is very simple. Just a mic element, speaker and some switches. KMC-45.pdf KMC-52D.pdf

I have 2 of these. I have used these with a variety of antennas and the suction is secure- even at high speed. Rx/Tx are both outstanding. I needed a no holes/no damage mount for my car. If you search on here for HCCFCA you'll probably find it.
