The purpose of an I-gate is to listen to the local APRS frequency and inject the APRS beacons it hears into the APRS-IS server system. I-gates do not digipeat unless they are also set up as a digipeater.Let me understand this, a iGATE does not connect to any internet server and only rebroadcast the transmitting up to three times to the digipeaters and IGATE are only used to extend the coverage.
Since most APRS activity in the US is on 144.390 MHz, most I-gates listen on that frequency. Also, most APRS activity in the US is simplex.Question are all IGATE on 144.39 QSO simplex?
Have no problem doing what? If your intent is to set up an I-gate, all you need is a radio that can receive on the local APRS frequency.so no matter what I can get a cheep radio set on 144.39 Mhz and have no problem?
I'm not familiar with that radio. As long it will tune to the local APRS frequency in FM mode and there's a way to get the receive audio from the radio to the TNC, it should work.I was thinking a regency HH4B or something along that line.
I-gates don't rebroadcast anything over RF. A reverse I-gate watches the APRS-IS datastream for particular types of APRS traffic that should be transmitted locally over RF, such as APRS messages sent to stations that are near the I-gate.Question 2 how come you don’t see IGATE using directional antennas pointing to the digipeaters for rebroadcast.
DirecTV dishes are tuned for microwave band signals coming from satellites. Those frequencies are far removed from the 2m amateur radio band.Since there are so many DirecTV dishes bandit this would be easy to do?
