A friend and I had a pair of these in the mid 90s. We sold them after a while since we were young and dumb and had different interests. Recently, we got nostalgic and I found some again. I picked up a pair and they are the same as I remember. The secure voice is amazing. In the years since then I had use everything from Motorola Securenet, Securenet DES-XL, then encrypted P25. I recall these things sounding better than all of them. Well, the pair finally arrived today and I tried them out. They sounded just as good as I recall from 25 years ago. There are a few left. I think they are programmed to MURS but I haven't checked yet. I bought the EX programmer box from him so if you end up with some I should be able to help you out.

Oh, and yes, they were all secure keyed the same.

I have no connection with the seller, just giving a heads up if anyone is interested.
