<div>Hi Ron,</div><div>If you are interested in specifically using APRS for MS on 6 meters, you will need to setup both ends of the path, just as you have done. There is little-to-no 6 meter APRS activity on 6 meters to use as a "base".</div><div><br></div><div>Operation requires a transceiver and/or amplifier that is capable of 50% duty cycle (use a Fan!). One station will TX for 15 seconds while the other one RX's. Clearly, you must coordinate TX and RX intervals.<br></div><div><br></div><div>The more power you transmit, the easier it is to make a contact (a general principle that transcends MS-specific communication).</div><div><br></div><div>Some degree of success has been had with as little as 25 watts + 10 dBi antenna (250 watts EIRP) at 6 meters.</div><div><br></div><div>Success is largely defined within the "time dimension" (being able to operate for long periods of time). Since everything is computer controlled, it is possible to select a seldom used frequency and let it run over night...taking advantage of the spike in MS ionization that occurs from 3 AM to 9 AM local time. This works well if you are allowed to run under "automatic control" (like an FM repeater does) rather than being forced to have a human operator present at all time.<br></div><div><br></div><div>FM APRS works well. So does the SSB mode. You can experiment to see which provides a superior experience.</div><div><br></div><div>'hope this has helped as a bit of a primer.<br></div><div><br></div><div>Best regards,</div><div>Ev, W2EV</div><div><br></div><div><br></div>
