The upper and lower rods both determine the lowest frequency at which a discone will work. The lower rods should be one quarter wavelength at the lowest frequency, and the upper rods are 0.7 of a quarter wavelength. I have a Diamond D130N discone. The upper elements are 22 inches across, and...

Still learning the ins and outs of DSD+ Now that I look back at the DSD logs from my previous monitoring of the two sites, I see the LCNs were indeed there. Fortunately, as Mike pointed out, this network appears to be using a standard band plan, so relating LCN to frequency is straightforward.

It appears that my scanner may have mapped the LCNs incorrectly for the Sayre site 17 After running the LCN finder on this site, and reading the results back into Sentinel, I had the results in my initial post: Sayre: 451.4250 LCN 739 RAN 17 451.7500 LCN 141 RAN 17 (CC) 461.1000 LCN 489...

Thanks Mike. I know the the “radio topography” around this area well, and the sites you have listed as potential “hits” for the neighbors of the Sayre and Jackson Summit sites make perfect sense. Thanks for the link to the spreadsheet and formula for LCNs. It will give me some practice...

Hi Mike Here's the info you requested, hot off of the air: 2019/04/21 19:25:24 L264-17 neighbor: Site L264-4; CC=182 2019/04/21 19:25:24 L264-17 neighbor: Site L264-5; CC=556 2019/04/21 19:25:24 L264-17 neighbor: Site L264-18; CC=787 2019/04/21 19:25:24 L264-17 neighbor: Site...

I can add some information on two of the Industrial Electronics Nexedge 9600 sites in northern Pennsylvania. My monitoring location is in Elmira, NY (Chemung County), which is just a few miles north of the Pennsylvania border, adjoining Bradford and Tioga counties. Monitoring equipment...

I don’t see anything on 150.830, but if the site is indeed in Barton, it would probably be blocked by the hills on the east side of Elmira. I’m planning to install SDR Console and DSD+ on a Windows laptop, so I can drive up to a hilltop with the RSP1 SDR. I can probably see the new site on...

I haven’t seen any voice channel decodes on the Horseheads CC yet, but will keep monitoring. My signal quality from that site is excellent. The tower is about two miles line-of-sight. The nice thing about using the RSP1A SDR to look at the band is that I can see at a glance the relative signal...

A quick intro, since this is my very first post on the forums. I have been involved in radio communications for most of my life, both as a hobby and professionally. I worked in LMR from 1982 to 1993, first at the Motorola MSS in Elmira, and when that company imploded due to infighting between...
