Been using Unidens all my life. I've also owned, briefly, a TRX-1, a Harris P7100 and 2 G4's.
I liked the TRX-1 memory architecture, individual talkgroup recordings and scanlist selection. However, P25 reception sucked compared to the Uniden436/536.
The Harris was a great rig, I could make a scanlist on the fly and hold onto any tg. Battery life was good. However, heavy to carry around and I couldn't program it (had to send it out to someone else).
The G4's I sold because I used to listen to a very large system, no matter how I looked at it, couldn't find a way to program it "creatively" and achieve satisfying results, I always found myself wanting a tg hold, nuissance skip and a wired earphone. Despite repeated pleas from scanner users for them (Unication) to consider putting in scanner like features, nothing was forthcoming. I get it, we are not their target customer, I accept that.
Now, an encryption skip feature is in "beta". Whenever they do release it successfully, I'll open up the wallet again.
Not to bash the SDS100, I really want to like it but the battery life doesn't cut it for me.
The videos that I've seen online side by side with a Unication, seems to give the edge to the Unication.
Every now and then I can hear in these videos the SDS100 gurgle when receiving simulcast.
I moved to another area where I can monitor a smaller amount of tg's and the G4 seems to fit the bill.
