Has anyone found a way to improve the transmit audio quality from the ID-1 with the HM-154 microphone? It seems that this combination is lacking in the upper audio frequencies.
When using a repeater to crossband to a IC-2820, the lack of fidelity is evident when listening to the ID-1 on the 2820, and the fairly good quality of the 2820 comes through the ID-1 speaker. This all points at the ID-1 or HM-154 as the item not being the best. Since it's digital from the radio, through the repeater, and out to the next radio, repeaters don't affect the audio quality; they just pass bits.
