As has been said, it has been discussed elsewhere, but I still hold to my assessment when the TRX-100/200 was cancelled.
All of the scanners offered to this point were technology that was the original intellectual property of GRE that they had purchased. They have never successfully introduced a new scanner to the market. The 1080/1095 was the final development of the PSR-800/900, the 1088/1098 was a Class II permissive change to the 1080/1095 that simply added a more robust keyboard entry and the TRX-1/2 was another Class II permissive change to the 1088/1098 that made very slight changes, even though they marketed it as an entirely new radio.
The TRX-100/200 was going to be their first original entry into the market but there were never any FCC applications filed, which means it never got to the testing phase before Whistler abandoned it. There is some speculation going around based on the timing of the announcement of the products that it was actually just a ruse to accelerate Uniden's release of the SDS200 in the hopes that it would be incomplete upon release, like the x36 line and they could capitalize on the shortcomings. Whether or not that is true is anybody's guess.
The fact remains that all they have done is sell someone else's scanner. The technology they are selling is over 10 years old and has been replaced with much newer and more efficient technology-which they have not been able to keep up with. The addition of the scanner antennas to their product line was a huge gimmick in my opinion to make it appear that they were still in the game-they could have at least picked less gaudy antennas. Unfortunately some people fell for it hook, line and sinker even though these antennas had been available on ebay for years.
I understand that in these days of COVID, it's more difficult to source your parts and coordinate overseas production, but as pointed out above, everything is showing sold out. Add the fact that many of tthe online retailers are no longer carrying their product and I think the writing on the wall is pretty clear. I believe Whistler has produced their last scanner. They currently don't have the in-house talent and I don't think the market is worth the investment to bring it in. I have said it before, if they want to remain competitive they should look into a collaborative effort to produce a scanner with Unication. While they would have to share profits, the radio would probably blow everything else out of the water.
