DSTAR simplex performance
During the ARRL VHF sweepstakes I threw out a call on the local DSTAR simplex frequency of 145.600 MHz, with 25W from my IC-2200H through my collinear antenna with its base at about 20ft. Rick, VE3CVG, responded and said I was booming in. He was using 5W (from his IC-91A/D, I believe) and his collinear antenna on his tower. I dropped my power to 5W and Rick could still easily copy me. When Rick dropped to 0.5W it was too low a power and his signal was garbled for me. I am in Greely, ON (South of Ottawa) and Rick is in Cumberland, ON (East of Ottawa), the distance between us I estimate to be 35km. Not bad for a 5W to 5W QSO on 2m.
So for those using DSTAR radios, do not forget to try simplex as well as the repeaters and gateways. DSTAR may have the edge over FM when used simplex. If you have had any similar experiences of DSTAR simplex then please share them and post them in a comment below.
