GRBAlpha - How to use digipeater or DNxD - 13. Frequency settings for digipeater or DNxD
The uplink or downlink frequency of GRBAlpha is 435.025MHz. There WAS 145MHz for uplink , but it is not work because of some trouble.
As I wrote in "GRBAlpha - How to use digipeater or DNxD - 05. My antenna, transceiver, and tracking system", I memorize 5 sets of frequencies with 5kHz step for transmitting and receiving just like when we use ground repeaters. The frequency pairs are like as :(uplink/downlink) 437.015/437.035, 437.020/437.030, 437.025/437.025, 437.030/437.020, 437.035/437.015. According to checking the frequency and direction with Gpredict, I change the memory channel starting from the pair of "437.015/437.035(uplink/downlink)", and I control my rotetor manually.
