Re: FIRMWARE VERSION 17.01.01

I recently acquired an APX1500 and was going to flash it to current, guess I'll go with one of the R16 versions.

Re: 12 dB SINAD vs 5% BER

I have always liked digital modes for exactly what you illustrated. With permission, I might include these clips and test data in my next presentation to a CERT group that is adamant against going digital for the sake of the old-timers not wanting to mess with "those new modes only cops use". It ma...

12 dB SINAD vs 5% BER

Performed an experiment about six months ago and figured I'd finally stop sitting on the audio. This test compares the audio quality of 5% BER versus 12 dB SINAD (i.e. the points at which we spec analog and digital receiver sensitivity to) as it is reproduced by a 7/800 MHz Motorola XTS5000 with fir...

Re: P25 Techs from a Different View

When I tested a VHF MASTR III and compared it side by side to a MASTR IV I was not all that impressed. Note, my understanding is the only real difference between a MASTR III and IV is that the IV has an optional modem card which allows it to handle P25. In talking with several Harris techs, adding t...

Re: Interop Between Type I & II

Long term I'm going to either go to Type II (potentially in the form of an IR site) or just straight to P25. The other weekend I had to run down there and much to my dismay, two of the three Quantro's were flashing PA failure errors (turns out the cavity combiners drifted after not being truly PM'd ...

Re: Odessey Control Head Discrepencies

The only thing is, the CPS knows its the Odyssey head. I've noticed that if you convert from a W series to an O series head it'll be on the same line but if it's initialized as a O series head it will be correct. However, my archive was a case of drag-n-drop from a W9 archive so that may have been w...

Re: APX 8500

At the beginning of may, I put 30 APX8500's into service for a PD. Waste of money for their application IMO but that's what some bright sales person sold them. Please note, I'm not saying that the APX8500 is a waste of money, it just was in this case as the city's emergency services were doing a for...

Re: Resources for Info On GE Orions

I wrote down the flash but I’m still learning these. This one came from a area where edacs was just abandoned (5 year migration with P25) and a few years ago the Phase 1 System went Phase 2. 800 MHz with EDACs is what I currently know. If it came from where I'm guessing it came from, it'll have EDA...

Odessey Control Head Discrepencies

Afternoon gents, I have an interesting discrepancy between two O5 control heads which I can not figure out. One, Zone name is on it's own line above the channel name. The other, it's in front of the channel name. Both of these radios were shipped as O5's however, the one that is displaying the zone ...

Re: Interop Between Type I & II

Yea yea...I'm trying to figure out a solution. We are likely ditching our TRBO solutions in the near future so I've got to figure out something else to get them on. This one just came to me, what about a mixed mode Intellirepeater? Might those Type 1 subscribers still function properly if I moved th...

Re: RE: Re: Interop Between Type I & II

I think he is migrating from a separate type I to a different type 2 system. If they were on the same system then the TGs can be hot patched together until all the units are on the new TG and format. Oh ok I wasn't sure what he was trying to do. If he has one of the 6809 based Start-Site or the lit...

Re: 7.16 Release

7.11 is the first P2 TDMA release. X2 was 7.9 I believe. Which is why I suggested your wealth of knowledge. Saw one of your Cherokee driving co-workers yesterday...

If I'm not mistaken, 7.1 won't support TDMA (X2, almost certain Phase 2 requires at least 7.14 or somewhere around there). iknowradios can chime in here anytime...I have a feeling he may know the answer to this question. 7.11 is the first P2 TDMA release.

Re: Conventional Status Settings

The status message should pop up on whatever console(s) is monitoring that TG. The status button decode is routed by the site controller filter subroutine from the master logger to the TG handler subroutine that way only the dispatcher for the TG sees status only for units on the TG. Units in scan ...
