That does make a difference, but what is the actual difference? How much of the difference is due to the antenna? Are the cables exactly the same length? Have you tested the insertion loss for each cable at each tested frequency? Remember, attenuation in an antenna makes SWR appear better. I believe these are the tabular results and I’ve arranged them by frequency It appears the older cable actually results in lower SWR for the 2 meter and 70 cm bands when connected to an antenna designed for those frequencies according to the value in the upper left of the screen. It would be interesting to see a single wideband sweep of just the cables into a dummy load to eliminate the effects of the antenna. Frequency Old Cable SWR -> New Cable SWR 462.000-470.000. SWR 1.900:1 -> 1.495:1 441.000-450.000. SWR 1.464:1 -> 1.498:1 151.800-154.600. SWR 1.888:1 -> 1.408:1 144.500-146.400. SWR 1.151:1 -> 1.395:1

Can you receive those same repeaters as well with the shorter antenna? You answered your own question.

Welcome, Zack!

There’s a very high probability that he has everything unlisted because he doesn’t want to allow anyone else on it. That’s his prerogative. Stalking him probably won’t make him more amenable to allowing you to use it.

Seriously, why not? They are not that much different to install than PL-259. In fact with these M&P connectors you don’t even need solder:

In only two characteristics is the PL-259/SO-239 system slightly better than the N connector: ubiquity and durability. A person can break an N connector, but it requires a certain carelessness. By ubiquity, I mean that I think I could find a PL-259 and SO-239 connector anywhere in the world. I don’t have the same level of confidence in the N connector anywhere. However, in every other conceivable characteristic, the N connector is superior, especially for UHF.

Yes, using cross tones/codes will work that way. I don’t know of any benefits to doing that, but yes. Anybody nearby, listening on 462.550 with no tones or codes, can hear anything that is transmitted by either radio.

Oh, no. You’re not getting off that easy!

Me too and I still owe you a beer!

I still don’t know what the length is, but rg213 still sucks for uhf.

You don’t mention the lengths of your RG-58, but for UHF almost any length is too much, but lossy cable like RG-58 will always make your SWR appear artificially low because less forward power reaches the antenna than passes through the meter so there’s less power to reflect AND much less reflected power reaches the SWR meter after reflecting from the antenna. So although the losses in RG58 is a problem, it’s not the cause of your SWR reading higher. Second, although a short or an open can be detected by a multimeter, the effect of RF frequencies is completely different. Yes, detecting a short would be reason to discard a connector or a cable, but resistive losses, the 002 (I assume that’s 2 millions?) that you measured are nothing to worry about. Without a dummy load and antenna/coax analyzer or nanonva your best option is to simply remove a piece at a time, replacing it with a known good component.

If the SWR doesn’t go back down when you remove the arrester, the problem isn’t the arrester. You either have a bad connector, cable, or antenna. Swap each piece out individually until you isolate the problem.

If you take the lightning arrester out does your SWR go back down?

Exactly what I meant by intercom.

Based on GrouserPad’s experience that’s not uncommon, unfortunately. There’s no reason to doubt your (or his) experience. TD H3s apparently arrive dead or die shortly after. Don’t waste time double checking yourself. Send it back, preferably for a different radio. You’re fine starting another thread but you would have been okay piggybacking on GrouserPad’s thread. Welcome to the forum!

There’s no way for it to get too hot except while transmitting. It’s the final output transistors that require cooling.

Have you tried VHT + TX? Doesn’t it only turn on the fan while you are transmitting AND the temperature is too hot?

I did.

That can be changed in menu 51.

Has that recently changed? Because three years ago I was automatically assigned AI7KS after I passed the AE exam.

It can be a frustrating thing to not have a clear cause and effect. It certainly could simply be group of failures caused by a bad batch of components.

Here’s what Gil @WRUU653 found: “Yeah, there is something glitching, I found if I turn on both stale and offline tabs all the repeaters disappear from the map. But if I click on a repeater that is on the map and then click on that repeaters info, then go back and select stale and offline they show up. A ridiculous work around. I had wondered if this was because of my security settings as I hadn’t seen anyone complain about it. I’m using IOS on an iPad. I’ll go put on some coffee and see if it behaves the same on my Mac desktop. I’ll let you know what I find and I guess we should let Rich know.”

They can be made to appear in the map view by going to the list view first but there’s either a bug or a poor design that causes problems if you start in map view. I’ll dig up the complaint I turned in. Also, Gil I think found a workaround. Here is my complaint to Rich, which matches what you said:

<sarcasm>Not really </sarcasm >

Unless removed they should still appear when old data is selected.
