Wrong on both counts. I have several seats of RT Software and there are some very serious bugs in those seats which manipulate linked tables of DMR zones and groups that can completely corrupt a codeplug. Having said that I will continue using RT Systems software, avoiding those features which corrupt memory. As far as Chirp goes although it is free, it is no sketchier than any other software I’ve used and the developer is very responsive. I’ll continue using it as well. As far as triggering malware detection software I’ve seen false positives on several different CPS programs by various antivirus programs. The reason is heuristic detection. It works by watching for snippets of software that resemble malware. Programs intended to program radios match that pattern, even though they don’t have actual malware embedded. That has been discussed before; it’s not new.

I’m also a fan of RT Systems software. While there may be occasional bugs, the company does work with the customer to resolve issues promptly when you contact them. I had a code plug I like for the Icom 2730 and when I picked up the ID-50 I found issues when pushing that code plug to the handheld. RT claims the fields should populate to correct fields, but I didn’t find that to be so. A quick call to RT and a couple revisions over the next day, and problem solved. Nothing is perfect but I’m a definitely planning on using them moving forward.

From the Chirp page: Warnings from AntiVirus and AntiMalware software about CHIRP Users of CHIRP may experience false positives from their anti-virus/malware software, their browser, etc. Unfortunately, there are not easy solutions to this problem as CHIRP is a volunteer effort without the financial and legal resources to secure agreements with these companies. Further, CHIRP releases fixes and features very often, so that users get the latest stuff as soon as possible. That means the "reputation" for a given version of CHIRP may be lower, the newer it is. For more information about false positives and AntiVirus in general, see some if these articles: What are antivirus false positives? How to tell if a virus is actually a false positive Still paying for antivirus? Experts say you probably don't need it Below are some common examples of what you may see, and how to handle them. Recommendation: Tell your antivirus provider that the file is not a virus! They won't know if you don't tell them and especially if you're paying for their services, make them get it right. If you can report the file as safe, it helps the other users of CHIRP because it decreases the likelihood of them seeing a warning and improves the general "reputation" of the CHIRP project.

How long have you had the DB20-G? Did it work before? You are probably encountering "desense" between your DB20-G and the mobile as they are too close to each other. If you can drive away and have someone work you from the DB20-G that is a better test. What Channel are you using for Simplex? The older units, including the Anytone AT-779UVs, did have a microphone hole issue, but the more recent generation of these mini-mobiles have mostly fixed that problem. Don't use Tones for Receive for now. That may also be the problem.

Go with RT Systems software. Yes it costs a little, but it just works flawlessly. Chirp is free, sketchy software for radios you don't care if you brick.

Thanks for the article, it's definitely an eye opener in some of the properties I took into consideration in a highly unscientific way. As an experimenter and hobbyist when it comes to building antennas, the two features I naturally and instinctively took into consideration is reflection and absorption of RF. I definitely want to get more in-depth in Ashby. My logic for using PVC is it is readily available, easy to work with and inexpensive. The real question from an RF perspective, does it have a negative impact on performance operating on the frequencies we use? I really haven't found any, especially measurable ones. Granted, there are better materials for structural and longevity, but will they perform any better electrically? Maybe, maybe not. I guess what I'm trying to say is any materials we have access to as hobbyists is going to have its positives and negatives that we have take into consideration for ourselves if the material is usable. From an academic and mission critical perspective where costs and availability are pretty much not a major issue all these properties must be considered.

Thank you and Merry Christmas to you as well!

My money is on a tone being stored on the channel.

Hello, I have this setup currently programmed for 467/462.5500 PL 127.3. Works great but it turns out i need to change the frequencies. I bought a single M1225LS to play with and it reads/programs fine. However, I put either one of the repeater radios on it and they both say the radio is not active, check cables etc. etc. Does something need to be done to activate them for programming? Thank you for any info provided. I'm using the LS/CPS v3.0 if that helps.

Dual-boot is a blast, for sure. I used to run a Windows / Ubuntu dual boot, which was helpful for doing design work for endpoint software and scripts. With an OS-based hypervisor, you can run as many simultaneous virtual machines as your available resources allow, with whatever OS you want, without ever having to shutdown the host OS. Also, as long as resources are managed correctly, none of the other VM's should ever impact performance or availability of the host OS nor any of the other VM's. The only constraint is, if you shutdown or reboot your host OS (the main operating system instance on the computer), all of the guest virtual machines will also be restarted and/or shutdown. With automatic dynamic resource allocation, I can run 7 to 10 guest virtual machines on my PC and not miss a beat. The biggest benefit to the typical home user is complete isolation from the internet. So there is no risk of virus or malware attacks, data loss or theft, or privacy violations (when combined with VPN service, anti-virus software and some common sense about what not to put on the VM.) It is definitely a bit advanced for the average home user, but there are a ton of resources online that can provide step-by-step instructions. And I know that since you are able to figure out a dual-boot system, which is much harder to accomplish IMHO, you should have no problem getting an OS-based Hypervisor setup.

If you run something that infects your VM with malware you just blow it away and create a new one.

i'm just trying to wrap my hands around how a VM would benefit most everyday home computer users. If just for testing/expermiting with software, Windows 11 and IOS have sandboxes for that purpose.. I can see for business pourpose on a larger scale how VM and VN is a huge benefit. I run both Windows 11 and Linux on my Windows box through a separate boot. Can you actually run both without rebooting with a VM? Now that would be cool if you could, that might get my fancy.

Yes, I've tried hitting two separate repeaters that are both line of sight from my house. I'm using the same tones that are working with my 6 other radios. One repeater is a few miles away at 3000ft, the other is 12 miles away at 1500ft. I can physically see the repeaters from my house, which is on the side of a mountain at 1000ft It's either a programming issue, or faulty equipment. I'm going to hook my nanovna up tomorrow and test my antenna and coax, then go from there

"I’ve been an RID man for two weeks now. When am I going to catch a spy?!"

Yes, I get a full red line showing TX

I was coming into this & expecting to tell you to use the LS version software, but seems you've already got that. Makes me wonder if the radios are actually standard M1225's with an LS housing snapped on ? Can you compare the model number to the radio that does read/write? I've also heard of some folks snipping the mic jack leads to keep people from messing around with 'their' programming. Take a minute or two and check that out if you bought the setup already programmed by someone else. You should also check the mic jack connection to make sure they are clean and not corroded. If the repeater was sitting without a palm mic plugged in the jack, it's possible that it's just dirty and not making a good connection.

I should also mention that if you have really old XPR8300 firmware, setting up your channel in Dynamic Mixed Mode will NOT allow for CWID to go out at all via the repeater. Set up a single channel as analog only - remove/delete any DMM channel, and CWID should work. If you plan to use it for GMRS, you probably shouldn't be using mixed mode. If you truly want to use DMM, you shouldn't be using a first generation XPR8300. Those had limited feature sets and limited memory. The later XPR8400 was the improved version.

a topic in Gigaparts forum suggested using virustotal because of the false triggers and apparently it works. Awhile back I got stupid and decided to try running a KeyGen for latest Autocad.. I almost executed the download but then decided to try running the download through VirusTotal, it lit up.. yea I did end up subscribing to Autocad 360 Ouch!!

I’ve not found a mic gain setting but there is an xmit inhibit setting. Which channel is it? Post your configuration file and let us look at it. There is a per channel checkbox for Compander, which just sounds bad on the db20. I recommend unchecking it. And Merry Christmas!

Merry Christmas Lauren and welcome. I’ve reported your post to Rich (the administrator/owner). He’s very helpful.

Those settings will work, but you need to have the unit set as a repeater. If you use an external controller, you're probably setting it up as a Base, and allowing for external control of the repeat function. I'd strip PL for CWID transmit.

Export the channels from both and compare them.

He's a clown that does not know what he's talking about and a shill that only says what his Chinese handlers tell him to say. I saw a licensed H.A.M. radio operator proclaim all this right here in this forum so it must be true because the guy had a license!

I don’t think that it’s as simple as that. According to this document PVC is more polarizable in the presence of RF and has a higher dielectric constant than other plastics and composite materials, especially at higher frequencies. This document discusses the materials which are more suitable for use as radioed: https://www.curbellplastics.com/wp-content/uploads/2022/11/Plastics-for-High-Performance-Radomes-White-Paper.pdf

Ahh, I see. Here is where it blew up overnight. As someone whose wife is confined to a wheelchair I can absolutely understand why a person with a kid in a wheelchair would feel upset about a comment that uses a kid in a wheelchair as a simile for being helpless. Until a loved one has been in that situation you might not get it, but having a loved one disabled does make us more sensitive about things we might otherwise have understood differently. But I don’t think that Randy went to the extent of finding out that your child was in a wheelchair and deliberately chose that as a way to goad you personally. I think it was just one of those insensitive comments that people make. I understand Ken being upset about the language also. How about we all go wrap gifts or something and take a mental health break. The unfortunate thing is you are people who might actually like each other in different circumstances, but because you’re only seeing that one sharp edge that’s being presented that’s where your focus is.

My wife told me NOT TO speak to her in that tone. I switched and haven't heard from her since! What can I do?

as the @AdmiralCochrane very eloquently said, GMRS is not for "making contacts" or chatting with anonymous men - for that, you're better off using the Grindr app on your phone. GMRS is for staying in contact with people in your group whilst off-roading, hiking, road-traveling, etc.

MtPleasant here. Mostly monitor Thompson Station Brentwood. I am also KQ4QQO and monitor Columbia repeater. I would like to see a complete list of local repeaters with name and frequency and tones if there are any new ones other than mygrms and repeaterbook and agree need more repeaters around here.
