Hi Rick, The numbers for the models seem very optimistic. Normal gain for J-pole (theoretical) can not be more than a dipole, since the antennas is an end fed dipole with the Q section for matching. This means at most 2.14 dBi, but maybe you are experiencing some ground gain which you can

Re: [digitalradio] Re: Odd noise in receiver

Thanks, Gary! I'm trying to be open-minded about this. Today the noise seems to be gone completely. It disappeared yesterday evening and haven't heard it since. If it reappears on Monday, I'll have a better clue that it's something that belongs to the local cable company. I used to work in

Here are some possibilities: 1. Teams have their radios on all the time, or perhaps only on the top of the hour for 10 minutes to check in - so their welfare and status is known and for delivering any important messages. 2. Teams connect to an email server via the radio at least once an hour.

Re: [digitalradio] Re: Odd noise in receiver

I've never noticed anything from the charger for my Motorola, and sometimes I charge it right at the radio desk! Unfortunately, I haven't charged it for a few days, so I know it isn't that. Haven't charged anything or plugged anything new or different in. Noise disappeared last night and

Howard, Some really good information. Do you use the RFSM8000 server for local e-mail like we used to use for packet, or do you connect into the internet to go outside the ham RF paths? Or maybe both? Do you just use the call sign or some kind of e-mail address? If you buy the server

Hi Howard, Thank you for the interesting reply. It is the first one that I've seen that actually addresses the core issues. Certainly, your item 1 suggestion, have their radios on all the time is a necessary fundamental for push messaging to work, and it is the prerequisite for it to function.

Judy and I did further testing of 1/4 wave and 5/8 wave antennas for 2 meters on her vehicle using the ICOM IC-7000 at 50 watts out. The base station continued to be the 30 foot high homebrew J-pole and now has 100 watts out from the ICOM 746 Pro. The mobile antennas were only mag mounts, but
