***PART 1 OF 2***

Hello all,

I just recently returned from a trip from Guatemala and brought along a scanner and SDR to see what the scanning world was like down there. A few important notes:

1. Most of my scanning occurred at a high spot near Lake Atitlan so many of the systems I heard where quite a distance from my location. I did do some scanning in Guatemala City, but had very little time there so I didn't gather much data. I did do some monitoring while between and in Lake Atitlan and Guatemala City.
2. I have limited knowledge of Spanish so I was not able to identify the users of many frequencies.



With that said, lets get into my findings. I will start with trunking systems first (site locations are approximate):

470.6000 FM CTCSS=173.8
473.3875 FM CTCSS=103.5


Other Notes:

The PMT personnel that I saw were carrying Kenwood HTs in Panjachel and a PMT unit I saw in Sololá was carrying a Baofeng UV-82.

At least in the Lake Atitlan area, the police that I saw were not carrying HTs. The trucks each had a small mag-mount on the roof, but I was not able to see if there was a radio inside.

I did not note any P25 or TETRA traffic. 800 MHz usage was mostly sparse. I did not note any VHF Lo band activity after a few hours of scanning it in the Lake Atitlan area.

You are a brave person, I would not contemplate bringing a receiver to a country I think might be confiscated or put into jail because of restricted equipment ? But it's great none the less to have an idea of what is going on in a given area, perhaps not knowing the local language or having a translator. Its great to visit new places and discover something previously unknown. Thanks for that.
