It's only a few parts but installing it in an Icom IC7300 **** IS
NOT EASY*** ! Read the Description and look at the photos.
You might permanently damage your radio if it isn't done
carefully. I take no responsibility for this if it occurs.
Locking an IC7300 with this interface requires ~10 dBm at
41.344 MHz, from a good external reference. Either a Bodnar GPSDO or
the GPSDO Reference Board described elsewhere on this site
can work well.
