Howdy,
I was wondering if anyone has had any success -- or if Rick has any tips -- for forcing the receiver center frequency to a predetermined value in Universal Trunker when using RTL R820T receivers.
I'm trying to eliminate the brief audio cutout I currently get in my recordings when the receiver changes center frequency to accommodate new calls on other VCOs on the same receiver. I have more than enough receivers and VCOs to cover the bandwidth and number of voice channels of the system I'm monitoring; however, the software has a strong priority to use the first receiver and the VCOs in order as well.
For example, say I am looking to monitor 852-857MHz. I'd like receiver one to cover 852-854, receiver two to cover 854-856, and receiver three to cover 856-857. Instead, currently, the program will utilize receiver one as much as possible. Say it is set to signal VCO at 853 with multiple voice VCOs. If a call comes on at 855 and receiver one isn't listening below 853, it would readjust center to catch the call on 855, disrupting a currently active call on 854. Instead of causing the shift in RTL tuning, it would be ideal if, instead, receiver two picked up the new call on 855.
In a voice VCO, setting the park frequency is just an idle parking spot when there are no other demands on the receiver (i.e., it will abandon that park if there is a call on another channel, even if it needs to jump out of bandwidth to take the other call).
So far, I can think of the following solutions, but each are less than ideal:
1) Buy more RTLs so each RTL has only 1 voice VCO. This would be expensive and would substantially increase computing workload.
2) Set two additional signal VCOs, with each parked on opposite sides of the bandwidth I would like to monitor with a specific receiver. I assume this would also increase computer workload, but it seems ideal compared to the above solution.
Ideally, I would be able to tell the receiver exactly where I wanted it to be.
