On the road again today, but this time with the G5 clipped to the visor, and the SDS100 in the cupholder between the two front seats. The G5 had its stock antenna; the SDS had the RS800 antenna (its stock antenna is basically ****.) The "test" knob position I set up for the G5 has all sites in Zone 3 (basically the Eastern Shore,) and 4 TGs: Kent, QA, Talbot and Caroline fire dispatch channels. The Favorites List I loaded in the SDS has all the fire TGs for Anne Arundel, and all the Eastern Shore counties (and all their systems,) A bit of background on how the G5 operates vs. the SDS100: The Unication radio will lock the first available site it finds, and stays with it until the radio moves out of range. Then it will search for the next available site in range, and locks it, and so on. The SDS100 acts like a typical scanner, and will search all the sites in the Favorites list that are not avoided (locked out,) or out of range. If a desired TG (not avoided / locked out) is active on a site that is being scanned, the radio will play that audio. What this all means is the the G5 almost always found a signal first. If I had set up the Favorites List mimicking the structure of the G5 knob position, I'm pretty sure they would have found the traffic simultaneously. What was apparent though, is that the G5 and the SDS100 found the same traffic (actually the SDS "found" more because it had many more TGs enabled.) The decoding by both radios delivered essentially the same DAQ in my opinion. The SDS100 was not deaf on many transmission like the PSR-800/WS1080, the 436, or my HP-2. It's worth the money if you listen to FiRST or AACo (does well with the digital audio on the police side - much less warbling.) The SDS also does a good job on the PG 700 system, but interestingly, I didn't notice a huge improvement on Montgomery's SmartZone w/ P25 audio system. I'll have to go back an test it again.
