External VFO includes fixed crystal board. Tested on the FT-101ZD - my only Yaesu rig in the Blaxland shack (that I use…). The pinouts for the VFO are similar but there is no 8v supply, and an earth instead. Hence the VFO works just fine but the grain of wheat dial lights don’t come on. They do test fine though. It matches the pale faced FT-107Z. Pretty good condition. Some marks on the top of the front fascia where a cable must have sat. Not significant though. Not common, but taking up space… Includes original manual..
