I have an Icom
M710 RT installed with a A130 tuner. I will try to boil the problem down as well as I can.
While in digital mode and using a Pactor modem
I have successfully sent and received hundreds of messages through dozens of stations.
When transmitting voice about 50% of the time I have issues. I will sometimes get the message "ERROR" on the display and the transceiver will reset. Other times the code "BUSY-PC" will flash and my transmission
will be strong but garbled to others. Occasionally loud beeps will accompany this message.
When I transmit and there are no messages on the display I am always told how strong and clear my signal is, many times thousands of miles away.
Does anyone know what those codes mean, or have any suggestions? I have checked all my connections, power supply, and ground plane. Using a watt meter an electrician checked my installation
and could find no issues and was impressed by my signal strength. I am in La Paz
and am at a loss of what to try next.
Thanks for the help,
