The Trident Raider does support PL and DPL, It was designed to allow a community repeater system to migrate it's users to LTR>
The unit is programmed and configured with a 1200 or 2400 baud serial terminal.? It requires a Televideo 920 terminal emulator for full functionality in the programming.
I have a dozen of these in service and would love to find a few more.
Trident Micro Systems was bought my Moto in December 2014 and almost everything was removed from the internet.?
TMS still exists in Arden, North Carolina but you can't get past the automated attendant.
If ANYONE has a Raider manual with schematics please contact me.? I'm also looking for Maurader and Extreme manuals and equipment.
Mike.

Karl,
Oh I'm well aware the SNV12 can do non-ST voting - it's extremely flexible! I just use status tone since it's sitting there anyway. Yeah, I wish they were less expensive.\

Re: ASTRO Spectra Firmware?
Just curious what the need for upgrading is as it generally does not add features or functionality.? ?You also need both a SmartRIB and OEM cable to perform such an upgrade.? You are not going to enable P25 or such just by upgrading firmware.? The version of firmware you need is also going to vary based on your hardware and configuration (trunking, conventional, etc).

Re: WSJ: Hytera and other brands banned by FCC
I hate to recommend this book, but about 75% of it is truly worth reading and so I will recommend it:
It details the history of cyber security with in the US - it also recounts Project Gunman which you can read in brief here:

Wanted Com Spec SS-32HB or SS-32SMP
Since the former one is defective I'm looking for that or the latter as a last resort. It's to help a friend with his IC-290 radio.?? OEM is NLA.

Re: WSJ: Hytera and other brands banned by FCC
Hytera had a pretty good product offering, but sadly they stole intellectual property, and from the wrong company. I spoke with a Hytera rep at the Orlando Hamcation a year before this came to light and he told me the founder of the company had changed the company name from HYT to HYTera because he wanted to end the era of Motorola (60 years at the time). So it seems the motivation may have been more greed of one individual than a Chinese military directed operation. I had been studying Motorola IP Site Connect and HYTera IP Multi Site connect documentation at the time and found specific language in the HYTera manual was clearly plagiarized from Motorola. So it was no surprise.
As far as the "internet" and security. It is a moldy slice of holy swiss cheese. There is no amount of effort that can protect ones data from malicious party's. Look at all of the products you own that interface with the internet. How many of them were built solely on US soil? What about the chips? None of them. There has been no effort by the US to bring strategic manufacturing back to the US soil. Why? Corporate Greed.? Corporations hire engineers with H1B Visa's because they can pay them less and they get access to all of the intellectual property in the US. At some point they get fed up and homesick and have a huge wad of cash in home equity or savings and they "retire" back in China where they can be hired to design missiles and radios.
This problem is manufactured here in the US by corporate greed and stupidity. Unfortunately the "powers to be" decided that they would sever ties with Chinese chip makers without first putting funding into US wafer fab.? Maybe the US DOD should cough up some of that investment like the Chinese military apparently does.

I don't know if it's possible to do a factory reset; however, I was able to adjust the receive and transmit frequencies by starting the programming software in the manufacturer mode, i.e., with a /m siffix.

Re: WSJ: Hytera and other brands banned by FCC
It has been a long time coming.? It is unknown to what extent these companies are conducting operations against the West.?
In order to BE a China company, any information/money/gain of any type is OWNED by the CCP!, so it should be assumed that
the extent of the espionage use of these companies is only limited by the extent that they are able.? Often the software TOS
has a clause that "you agree to be bound by the laws of China by the use of the product".? So in a way you have surrendered
your US citizenship to CCP jurisdiction without knowing it.?
The claim that NSA has been guilty of this kind of thing certainly doesn't excuse NSA or CCP or any other entity.? WE should
really be more consumer aware.? Do you really want your likeness and DNA profiles owned by CCP?
I don't know if you can still find the download site for "Project Venona" (i hope i got the spelling).? From the 1920s or so, lots of
encrypted traffic between the New York Russian Embassy and Kremlin were intercepted and saved but not until the Soviet Union
fell, did the decryption keys become available and analysts were able to see the full extent of KGB operations to gain info on
individuals in order to exploit "useful idiots" or blackmail people in positions of power and influence in order to bring about change
favorable to Russia and detrimental to West.? It is the cheapest way to spy.
Espionage is not just trade secrets, but information on individuals to best isolate and exploit them.? It was found after Venona that
these espionage operations, usually used "volunteers" (useful idiots, slaves) in the target country in order to insulate themselves
from prosecution. I can recall a foreign operative laughing at me and telling me - "Americans are lazy and stupid and traitors to
their own people, and deserve whatever happens to them".
