Montgomery County De-Sence

[KK4HG]

Not sure whether this should go here or under GRE so I will try here first since it is location specific.

I live very close to the intersection of 355 with Montrose Rd. I have a PSR600 with an indoor Diamond D220 mini discone sitting on my desk by a window. About 20 feet of RG58 cable between antenna and radio.

The problem I think, is front end overload from a very near-by MC trunk site. About 20% of the signals from the County are garbled. ATT helps but I don't like to leave it on for fear of missing something.

My TSYS settings are as follows:

Type: Mot 800/900
CC: 1. 868.6875
2. 868.8625
3. 868.8875
4. 868.9375
L/Out: Off
Expert
Atten: On
Narrow FM: No
Audio Boost: Off
Dwell: 0
Dig AGC: On
Super Track: On
Multi Site: Off
T Tables: Default
Fleet Map: Type II.

Is there some tweeking to be done or must I live with it?

Loss

20 feet of RG58 at 800 MHz is extremely lossy! Try
upgrading your coax to RG8 or even something better.

Every mobile antenna in the county is connected via 17 feet (or more!) of RG58. The loss at 800MHz is only about 13dB/100 feet. I'm pretty sure thats not his problem, especially since he stated he is likely receiving too much signal already since the ATT helps a little. If anything, I'd add MORE attenuation and see if there is improvement.

KK4HG how well do you receive the system on the back-of-set antenna?
