Hi, We're thinking about installing a repeater on the roof of a three-story building. I would like some opinions on how one should handle grounding ans bonding in this situation. This is a commercial

For my stuff here in Utah I use 100.0 and 103.5 for repeaters 110.9, 131.8, 141.3, 203.5, and 77.0 for links I’ve noticed sometimes 110.9 can be herd on the audio of some sensitive receivers All my

The higher the frequency the faster it decodes, consider DCS if possible. Regards, *Terry Griffiths* Emergency Communications Network Commissioning Specialist Marshall Islands ECN Communications

Well, that was the jist of the conversation. Repeaters on the same frequency. Adjacents are not an issue. But the coordinating body here doesn't "assign" tones, it's left up to the trustee. The

Look at the list of repeaters I listed. If you have multiple repeaters on the same frequency within less than a 60 mile radius, your frequency coordination council is not doing their job. Our

I found a trick to make the Epic V SCM work for analog operation - I believe Scott Zimmerman shared the info I passed in a previous thread. Never have tested it for P25. I'll reach out directly to

Is your repeater going to encode (ie transmit) CTCSS? If so you may want to pick a lower tone so your users with amateur radio grade radios don't complain about hearing a hum. Ham transceivers and

You have multiple repeaters on the same freq and tone within 10 miles?

Go DMR and have 2 talkgroups one on each time slot, then you can have one repeater that can handle two QSO at the same time. [email protected]> wrote: -- Chuck -- KP4DJT AREDN Meshphone #

Correct. 123.0 is used by almost all PS dept's in my county. Has been for 50 years at least. It's not a problem. Now, strong DMR on the input... Doesn't open squelch, but it can hold it open for a

If you keep the Bird 43 up at the top right of the scale you may still see movement. The problem with the 43 is that you need at least 2 slugs to do proper testing, especially in reverse VSWR. A

If your coordinator is doing his job, there won’t be another repeater close enough in frequency to cause a need for different tones. We run 146.67, 146.700, 146.76, and 146.82, all within a 10 mile

123.0 is popular where I own repeaters.? If a tone decoder set to 123.0 opens with a 120 cycle tone, IMHO it should be thrown away and replaced with one that works correctly. Kevin W3KKC

123 is close to 120 which is 2x 60 cycle hum....the higher the tone,the faster the response time in the decoder (usually) but it's not that much... Pick whatever you want...I use 100 (PL1Z) because I

Seconded. That doesn't happen 'round these parts...;c)

118.8

I did also check. The wattmeter I have for that is a Bird 43. The meter needle is too highly damped to see any sudden changes (which I didn't anyway) I wish I had remembered to bring a dummy load.

Ken, I would put a wattmeter in the antenna line and watch for a change when you hear the cracklies.? But this change may be very, very subtle so you need to watch very closely and keep the

In addition to previous suggestions, higher frequency tones decode faster. But are more noticeable in the audio depending on the radio/controller's filtering. have fun, Alan KM4BA
