Frequency/CTCSS Monitor/Logging Software

[lee.lockwood]

I am wanting to put up another repeater in my area.  However, before I randomly pick the frequency for it, I want to monitor the available GMRS repeater pairs for the "cleanest" available.  I know that not all repeaters are listed on the mygrms website, so I can't just go by the locations of them listed here.  Does anyone know of any software that can be connected to a radio discriminator or SDR device that will monitor and log PL/DPL tones received, as well as number of times traffic is received, and log it?

 

Back in the late 90's early 2000's, there was a DOS program that we would run at a two-way radio shop I worked for that did this.  But, I have no idea what it was called or where to find it.

Don't know the name of the logging software but you'll need to just scan the repeater input frequencies for traffic. It doesn't do any good to scan the outputs as they are available for FRS use.

Would hooking up a computer with some audio spectrum analyzer software work? You could set it to 'peak hold'; and I'd suspect you'd see a bunch of audio peaks held in the sub-audible range of the passband where the PL's rolled in.

Probably wouldn't work on DPL I suppose, but CTCSS should be fine.

I guess I should clarify... my intent is to setup the software/receiver and let it run for about a week on each of the repeater input frequencies, all while logging data.  I want to compare number of times RX traffic is heard as well as the CTCSS/DPL associated with it.  

I wish I could find the software I used 20+ years ago that did this exact thing.  There has to be something like this that has evolved even better since then.

A repeater controller like Zetron 38 or 48B has a mode where it will count activity on any of the tone slots programmed into it.

I'm looking for a simple software based solution.

There are a few different options. Any Uniden scanner and Proscan, or an RTL-SDR and SDRTrunk.
