Lightning Arresters - Surge Arresters.
SteveShannon replied to LeoG's question in Technical Discussion
If it’s one with both a gas tube and a blocking cap then yes it might be directional. Here’s a datasheet for a polyphasor with just a gas tube. Note that it says bidirectional: https://www.polyphaser.com/Images/Downloadables/Datasheets/103-0324A-A_datasheets_US.pdf Here’s a datasheet for one with the gas tube and cap. It’s also bi-directional. https://www.polyphaser.com/Images/Downloadables/Datasheets/098-1013G-A_datasheets_US.pdf Here’s a link to a directional one: https://www.polyphaser.com/Images/Downloadables/Datasheets/RRX4025A_datasheets_US.pdf -
No, but welcome! The mag base antenna may help, but see if it requires a ground plane. If it does then use a steel cookie sheet. A better antenna would definitely help.

Lightning Arresters - Surge Arresters.
SteveShannon replied to LeoG's question in Technical Discussion
If you take it apart you’ll see that electrically it doesn’t matter. It’s really just a gas tube perpendicular to the center conductor of the feed line. Mechanically, having the long side towards the antenna makes it easier to mount in a bracket with the antenna connector convenient to unscrew. -
Club memberships required to use (aka Pay to play)
SteveShannon replied to UncleYoda's topic in FCC Rules Discussion
If you look at the regulations they specifically prohibit operating as a commercial carrier but they say that companies who are licensed may operate nonprofitably. I’ve never seen anything that says a repeater owner can’t recuperate costs. Ham radio is completely different. There it’s specifically prohibited to charge. -
The OP logged in at 6:40 am yesterday and left at 6:43 am. He didn’t explicitly ask a question and he hasn’t been back. I responded by anticipating that he might be asking what to do with the information he had. I think most others did too.

FCC Shutdown of New York GMRS Linked Repeater System
SteveShannon replied to OffRoaderX's topic in FCC Rules Discussion
What happened in New York appears to have been a cautious reaction to an unofficial warning. That did not establish any kind of legal precedent. The FCC has a website that clearly says “any other network” in a way that appears to conflict with the written rules. What people fail to understand is that only the written rules have legal status and even the written rules can be challenged. If the FCC attempted to cite someone based on their “any other network” website interpretation they would have to show that their interpretation is supported by the written rules. That would be expensive for all parties but stranger things have happened. With the recent SCOTUS decision regarding Chevron Deference it may be even easier to defend against the FCC interpretation, but until someone is cited and fights the citation we won’t have anything other than our opinions to argue about. An organization I serve joined another similar organization to sue ATF in federal court over their classification of rocket propellant as an explosive (it isn’t). We fought for nine years. We prevailed and ATF had to reimburse us for our legal costs. Our two organizations had less than 15,000 members at the time. ATF was relying on their claimed expertise but we were able to demonstrate that they were technically incorrect. -
But not our women? Welcome! I think.

The TYT 9800 being sold now is the same as the TYT-9800 plus. I have no idea what the differences between these and the D model. There’s at least one video that demonstrates how to unlock the radio. From the website: Note: TYT TH-9800 is the same as TH-9800 Plus after 2018, all the stock from Radioddity is the latest version of TH-9800 with the latest firmware and cross-band function.

First, your radio has 30 preprogrammed GMRS channels. The first 22 are simplex channels, meaning they receive and transmit on the same frequency. Then there are eight preprogrammed repeater channels. They may be numbered 23-30 or something with RP in the name. They receive on exactly the same frequencies as channels 15-22, but when you transmit using one of them they offset the frequency by 5 MHz. Channel 17 receives and transmits on 462.600. Channel 25 (or possibly 17RP or RP17) receives on 462.600and transmits on 467.600. Whatever it’s called, that’s the channel you want to use for the repeater you mentioned. If you tune your radio to that channel you should be able to hear the repeater if someone is talking. The input and output tones are relative to the repeater. Your transmission is the repeater input. In order for the repeater to pay attention to your transmissions, you will also need to program the transmitter on your radio with the repeater input tone frequency. That’s the 141.3 Hz number. Similarly, the repeater’s output is what you receive. If you leave the receive tone empty you will hear everything on that frequency. When you’re first getting started with programming a radio I suggest that you leave the receive tone cleared out. Then, when you’re confident that your transmissions are being heard (activating the repeater) you can try putting in the tone. Then, you’ll only hear transmissions that include the tone. Hope this helps!

Welcome to both of you!

It’s molded into the cover. The top jack is for the headphone. The bottom is for the microphone. Both are necessary for programming unless you’re using Bluetooth.

I wish I could get my wife to buy stuff for herself. She and I talk about purchases, but I would never expect to control her purchases unless I was concerned about her cognitive functioning (not even on the radar!) and I think she feels the same way about my purchases. She might ask me what I bought if my monthly credit card bill is higher than usual, but it’s curiosity rather than control, but i usually will say something like “I’m ordering a new gun” or radio or computer. After 45 years we know how to communicate well. But, neither of us have ever had “my money” or “her money”. It has always been “our money”, so it’s only considerate for either of us to discuss large expenditures with each other. One of the first signs of drifting apart is when couples begin separating their money. We were adamant that wouldn’t happen to us.

Do you have another radio in the cab that you’re listening to when you transmit?
-
Yes, you misunderstood. The vertical width is a total of 7°. According to the documentation the default tilt is 0°, or horizontal. If you want it to have a down tilt you would have to contact the manufacturer and ask them to adjust the phasing harness (I assume they do).

People sometimes get hung up on height. We have 60 miles and several mountain passes between Butte and Helena Montana. It’s extremely difficult to get higher than the mountains to get line of sight. Yet we have a guy who checks into our 2 meter Net from Helena. We asked how. He does it by bouncing his signal off a mountain that’s in his sight line. I don’t know if something like that could be done in your instance, but look for high topographical features and see what happens.

I absolutely agree with you but as I’m sure you realize, tones do not reduce clutter. They simply mask it. If a channel is busy it’s entirely possible that an emergency call will never be heard. This is part of the fallacy of relying on GMRS for an emergency wherever it’s in heavy use. With that said, having a two way radio of any kind and knowing how to use it is infinitely better than having no way to communicate.

Did you do a search first? There are several threads which mention the TK-890H. One mentioned that they burn out quickly. Another mentioned that because it’s a 100 watt radio it would be a poor choice for GMRS. The people here with the most Kenwood experience and who post prolifically are @Lscott and @tweiss3. Maybe they have some insight. And here’s the results of a search: https://forums.mygmrs.com/search/?&q=TK-890&quick=1&search_and_or=or&sortby=relevancy

Given that it’s more than three years ago, you would probably have to check Craig’s List as mentioned in the original post.

New Repeater Channels for GMRS in 2024
SteveShannon replied to intermod's topic in FCC Rules Discussion
@wqnd300 and @WRXP381 You both are being obnoxious jerks. @Lscott has just as much right to be here and talking about what digital might bring to GMRS as either of you. He brings much more intelligent discussions and less judgmental rhetoric than you also. If you don’t agree with him, that’s no problem. He and I have disagreed about digital modes also, but it’s easy enough to disagree without becoming disagreeable.
