By "Active VOICE" means that DSD is decoding it as TRBO

452.3875 The Bravern in Downtown Bellevue

Getting fair reception using DSD as they are TRBO. Frequency sounds more like a general channel -- security, concierge-like services

464.925 Virginia Mason Medical Center on East Hill, Seattle

Strong signal and good decodes. A couple of docs making bad jokes.

Win7-64 and DSD 1.60

What scanner do you have? It needs a discrimator-tap output for best decodes...

PSR 800

Ah okay. I forgot to try my PSR800 with its disc output. I think I tried it before and had flakey results -- but will try it again tonight.

UPDATE: PSR800 is very flakey with IF out -- at least for me. I couldn't get any decodes. DSD acts very weird using PSR800.

I've heard some people say that DSD *requires* a resistor inline for any discriminator output, so I guess it's possible the raw output from the PSR800 is causing weird side effects with DSD.

I have a R/S Pro-2006 and BCT-15 with discriminator taps. They both seem to decode very well.

Example of BCT-15 tap: http://www.discriminator.nl/ubc800xlt/index-en.html

460.675 Frontier Airlines at SeaTac Airport

Good signal and clean decodes. Sounds like the usual handlers, agents, roving CS people, supervisors, etc.

FYI, I spotted this late last night. Per the Yahoo group the PSR-800 is very touchy with DSD. So in the PSR-800 software there's an IF level (volume level) adjustment. I turned mine down from MAX to 20 (scale of 30) and it seemed to be less touchy.

A couple of users suggested force DMR mode only. I still haven't heard any voice decode with the PSR-800 but it's much better overall.

I'll keep playing with it. It would be nice to have a portable solution for DSD.
