| The PA puts out ~20W and can be adjusted using VR1. The deviation is adjusted with VR2 and is set ~5KHz from the factory. On receive it's (apparently) very selective & sensitive, and the second IF filter is 20KHz wide so this TRX might even work on wider bandwidth modes. Using an IC-705 as a reference receiver the wideband PLL phase noise looks to be very low and there are no horrendous key-up transients a-la FT-1500M. | The PA puts out ~20W and can be adjusted using VR1.

| As we're using +/-2.5k deviation for these modes I also replaced the first IF crystal and second IF ceramic filters to try to squeeze every last fraction of a dB out of our links. | As we're using +/-2.5k deviation for these modes I also replaced the first IF crystal and second IF ceramic filters to try to squeeze every last fraction of a dB out of our links. | ||
