Recently I've noticed that I receive the mobile units of the GSP but not the bases. I've got all the troops from RR and I just noticed this recently. I'm able to pick the mobile units from 50 or so miles away. I'm using a Uniden 536 with a Tram 1405 base antenna. In the past I could pick up 5 or 6 of their repeaters. Just in the past couple of weeks I'm only picking up the mobile side of the communication. Anyone else notice this? Have they changed something?
