If you happen to be at the Hamvention this weekend, please stop by the HobbyPCB booth in building 1, booth 1912. We'll have the new 10th Anniversary Hardrock-50 and the 100W Hardrock-50+ on display and for sale.?
The RF circuit in the Neptune in surprisingly similar to the Hardrock-50's RF deck. The big difference between the amps is the control system; the HR50 is fully integrated with most QRP transceivers from Yeasu, ICOM, Xeigu, ELAD and others without relying on frequency detection. The Hardrock amps all have optional internal ATUs?
Hope to see you at the show.
