Flagship 100W CW ATU, currently undergoing field trials. Shortly to have 10 available at cost for beta testing. if you are interested and able to put time into testing and provide constructive comments on observations should drop me a message in the contact box.
Basically 100W, 10:1 L-network tuner,
Average 3 second first tune and 30ms memory tune.
1kHz memory resolution.
Special "Yaesu" mode makes use of LOCK button for one touch tune so no need to reconfigure CAT interface.

SPL100.
Still experimental. Using very expensive relays, this ATU lives with the Yaesu FT-817 and so far has been absolutely amazing!
25W CW, 10:1 L-network tuner, but in combination with a 4:1 Balun, 10m of stainless steel wire and a few 3m ground wires has allowed some incredible contacts.
Apart form power basically similar features to SPL100 with much faster 5ms memory tune (due to faster relays).
Uses same "LOCK" button one touch tune on FT-817, 857 and 897 so no need to reconfigure CAT. Or just use in automatic mode with other radios.

SPLmicro.
Better than 1ppb accuracy when locked.
GPS module has built in antenna so just put this in an IP68 "Jiffy box" out side some where and run power (5V) and a coax and there you have it 10MHz.

10MHz Shack reference.
Many of the popular Yaesu FT-897 radios are developing blank lines on the LCD. A failure of the technology of the day.
Replacemnts are hard to get and expensive, so many people "make due" with a bad display.
This module is a cost effective solution that requires minimal mechanical modification and will give years of trouble free service.
