Trunking Question about Holloman AFB

rilke67 · #1 (**permalink**) 04-18-2009, 09:26 PM

I have been monitoring the Holloman AFB, NM trunked system since uploading the data using WIN500 software. I noticed today that I am no longer receiving Holloman's system. What may be the problem? Could the frequencies for the system have been changed or is it something with the radio? I don not get the "T" which I understand to mean the scanner is receiving trunked information. I attempted to load just the trunked system and when the scanner was turned on to scan I received the message that there was "nothing enabled to scan" Any help would be greatly appreciated.

Any chance of you setting up a stream to monitor HAFB along with avaition in the area? Would love to hear the F-22 buzzing around!

I read through the post and it appears that the base freq is the one that is currently listed and it was the one being used when I could monitor both Holloman and White Sands. Since I can no longer monitor either i am leaning towards the fact the base freq may have been changed since it is the one common link between the talking groups. I checked Fort Bliss and the base freq is listed as the same as for Holloman . I think one will have to spend time searching for the new base freq for the trunking tables.

Any suggestions would be appreciated.

Thanks
Rick

Since I'm down there I would just search and find all of the CC's you can. Then try messing with the base freq to find one that will work like Rob did. Good luck!!!

Rick, any luck yet???

Today I tried frequencies from 406 using a 12.5 step thru the lowest control frequency with out any luck. I also did a scan of the 406 thru 420 freq and found 4 freqs that were p25 with a code of 305. They appear to be Holloman AFB frqs for security, fire, maintenance and ground control at the tower. I plan to monitor and see if I can narrow those down and maybe find some other before I send anything into the site.

Any idea where you can find what the tone code of 305 means as that is the p25 code that was appearing with these frqs?

Again thanks for the interest and help. Maybe this board will get a little more active. I have been thinking of going to the Texas board and seeing if anyone in ElPaso was having problems with the trunked system at Ft Bliss since they were/are using the same base freq/ Ideas?

Thanks again.
Rick

just some questions.... Are you trying all 4 CC's in a scanlist at a time, or are you breaking them up? Just wondering if we might have to set up a table to get it to trunk. Asking in the texas forums if anyone is monitoring Ft. Bliss is a great idea. The 305 is just the ID of the trunk system... since 305 shows up on all the CC's, that means their all connected.

rilke67 · #8 (**permalink**) 04-21-2009, 12:25 AM

I haven't loaded them into any scan list as of yet. Would they go into the trunk system? I am a very new to the scanning world so most of this stuff is greek so to speak. I plan to monitor more tomorrow and see if I can nail this down a little better. Setting up a table, now that would be a challenge. Let me know what you think and what you would like me to do and I'll give it a shot.

Thanks again

Rick

Yes, you need to enter the CC's trunk system, then attach them to a Scanlist, then create a wildcard TG under that scanlist. Make sure under the TSYS Object setup, ensure you pick the type as a MOT VHF/UHF. Also, click on the table button and thats where you need to stick the base freq in with offset. Good luck!

Erik

the freqs that were found while doing a search showed up on the conventional list and the scanner is receiving them fine. I am not sure if they are a trucked syste, or maybe I don't under stand all there is to understand. I have not gotten any response from the Texas forum but I would think someone down there is monitoring Fort Bliss. Do you still thinks these are a trunked system frequencies?

We have Norfolk Naval Base, Norfolk Naval Shipyard and Ft Lee all in Scanner Frequencies: Eastern Virginia Regional Communications Trunking System, Various, Virginia and Scanner Frequencies: Langley Air Force Base Trunking System, Langley AFB, Virginia

These are very similar to HAFB and each use 406.0000, 380 &12.5 settings.

Using base of 406.0000 at step .0125 leaves 48 unused channels in the HAFB band plan.
The same sample leaves 108 unused channels for Langley and 96 unused for Norfolk NavBase.

My bet is the system should work as a smartzone with above settings.

Disregard the 800 table settings in first grouping as they are for Hopewell Public Safety who conned their way into the SysID. Ft Lee is next door to Hopewell.

I have checked several military trunking system through out the US and all Motorola Type II SmartZone are using a step of .0125, lo hi chanels 380 759. The difference with most is the base frequency. It is my understanding that the base frequency is never higher than the lowest control channels. so what I have done is I started with 406 and stepped to 406.0125, 406.025 etc until I had gone through all the channels up to and including 406.225 which is the lowest of the control channels on this system. So I am at a loss right now. I have reset the defaults of the radio in case I did something there. When I load just the Holloman AFB system I get the first talking group to appear in the window and the hot keys are lit up with new edit and global which I have not seen before after loading the radio using the win500 software.

Thanks everyone for their help as I will keep plugging along.

so what isn't working? You just made it sound like it is trunking...

I happen to read this forum and came across your file, I don't live in NM or know anything about that system, but, I went by the info in the database and what you had in the file you attached, if you are using this file at home and not out roaming, try it and let me know if it works for you, if not maybe we can try something else. You may have to pick out the strongest site (Control Channel) and just use that CC. I hope I'm not out of line here!

Rick, also make sure in Win500 you have multisite mode on and set to Stationary under the TSYS you have set up for the Holloman TRS!

rilke67 · #16 (**permalink**) 04-23-2009, 04:46 PM

For the past two days I have been doing a limited search from 403 - 420. I have attached the WIN500 folder with what I have saved and what freqs I locked out for static. Traffic is from Holloman AFB and WSMR along with the US forest Service from what I can tell from the short time of monitoring the freqs.
One of the freq that is coming in loud and clear is 406.1125 which is also the base system freq for the trunked system I was monitoring before it went away.

I see the freq are now showing P25 NAC 305. So is it possible for them to have switched systems going from the Motorola Type II Smart Zone to a P25 system. If this is what they have done how hare is it to set up a trunking p25 system for this.

Not sure what is really going on since I am kind of flying by the seat of my pants.

Thanks

Rick

Its a trunked system and you should be able to monitor at least 3 control channels. P25 means that its digital.

rilke67 · #18 (**permalink**) 04-23-2009, 07:59 PM

thanks for the info. It will be nice if the guy coming down here can figure out what is going on. I will keep plugging away.

fmon · #19 (**permalink**) 04-23-2009, 09:56 PM

Rick,
Those with CT or DCS are conventional. Those with NAC (all 305) are likely P25 voice of a trunking system but listened to conventionally. Though there are many Project 25 conventional frequencies used which will present NAC codes. Kentucky State Police for example. Any voice frequency in a Smartzone can be digital while all voice frequencies in a P25 system is digital as are the controls.

Erik, I meant to get back with you all many moons ago, (like more than 6 mos?) and let you all know what I discovered about the WSMR control channels. Erik, remember you gave us 3 or 4 control channels associated with WSMR. Well, I told you that I put all these CCs in one bank, used parameters 406.1125/380/12.5 and have been listening to WSMR ever since.

I have noticed that WSMR (for whatever reason) alternates using CCs 409.775 and 409.3625 frequently. They use one of the CC for a month or so, or even up to two months, then switch to the other of the two. And the above are the only two they use. I've also noticed also that they use only 3 voice/data channels. I can't see how they can get by this with only 3 voice/data channels, especially when occasionally there is one project out there at WSMR or Holloman which uses the trunk system to monitor their project intercom conversations, with the trunk radio keyed on for minutes at a time (tying up the system and restricting the system to the use of only 2 voice channels for the other users).

I only listen to the analog transmission since I do not carry my 396 around and I only have a PRO-2077 installed in my car. In the open bank mode, I do hear the annoying digital transmissions as noise (the user id does come up). Maybe some day I will get a mobile/desktop digital scanner for my car.

BTW, any rumors of newer/updated versions of desktop digital scanners?
