I received my SDS200 last Saturday and a big thank you to Jeff at Ham Station. I gave a preliminary observation prior to the registration and DMR/NXDN keys being upgraded. Series ends in 1012.
From the other posts on the "humming noise" being evident, I also noticed this coming through my external speaker. The "dim key pad" is also evident, but don't know if that was be design or a true flaw? Either one is a not a deal breaker or "I have to send it back today" moment. That's just my opinion as i'm very tolerant of these minor skirmishes.
So onward...performance. Background is 40 plus years of scanning...from crystal days to present day technology. Owned a 10 channel Regency crystal scanner, 210XL, 785, 796D, 996T, 996XL, 996P2, 396T, 396XL, 325P2, 536hp, 436hp, SDS100, and now SDS200. So I have some experience under my belt and a large monitoring base...analog, analog trunking, DMR, MotoTRBO, NXDN One frequency and NXDN Trunking.
My SDS 200 is using an external speaker and outdoor antenna. No Pro Voice close, but all other systems available. It takes a little getting used to with the different positions of buttons and knobs, but like the others I managed to figure it out. The simulcast performance is good, but it was better as I noted in this thread I posted:

As I mentioned on the SDS100, the beta firmware 1.06/1.01.05 has performed better on Starcom P25/Phase 1 simulcast system. My unscientific opinion is the ERR was corrected a little faster and resulted in far less "choppy" transmissions. It's workable and better than the x36hp series, but seems to have degraded with the firmware and or Sub CPU firmware changes. I'm hoping something is in the works.
Another issue I previously reported involved the programming of a 454Mhz. 3.125 khz. frequency system:

After doing some additional work around's on this including filter adjustments, attenuator adjustments this is still problematic. The ERR rate on my SDS 200 is 0-10 on the control channel, but the scanner is not stopping on any transmissions. It "jumps" across talk groups. Both SDS's do accept the entire frequencies, but appears to be a decode issue....possibly related to the 3.125khz frequencies?
Another old issue I saw on both x36hp and SDS scanners is still occurring. This involved NXDN One channel programming:
https://forums.radioreference.com/t...ency-vs-conventional-nxdn-programming.379908/
On the SDS series of scanners, I have been able to properly decode and monitor a NXDN One frequency system on UHF (461.64375, 452.23125), but unable to do so on a VHF frequency (161.205). As I alluded to on the original post, maybe the TGID of 0 is being ignored? On One Frequency DMR systems that i've programmed, TGID's usually start with 1 and never have seen them "ignored" like NXDN One Frequency systems?
The scanner itself is performing very well on all bands. As I expected, the sensitivity has to be adjusted at times via the filter settings. I was not able to do so with the 536 or 436. This is a plus. Tracking of One Channel DMR CAP+, CON+ and NXDN Trunking Systems has been very good. No complaints as far as those systems go. Air Band needed some tweaking per channel, as I wish I had that on other scanners but have it working very well.
I know UPMan and UnidenSupport monitor these forums and giving some comprehensive findings usually result in future firmware update corrections. I like the size and display and would like to see a modification for UID Name as it's being cut off by the position of Avoid on Simple Trunk. If the Avoid indicator could be moved, this would result in UID names being allowed in it's entirety or close to it.
A good solid unit that is sitting very nicely on my desk..well done!
