Heathkit SB and HW series frequency meter and CAT signaler – Part 5 Reading , calculating and CAT
The project advanced again, now, I can read the signals, and send them to CAT so i can use it on N1MM or other cat sw. The signals, BFO, LMO…
Heathkit SB and HW series frequency meter and CAT signaler – Part 4 – First conceptual tests
Started to build the prototype today, some parts are ordered but have not arrived yest, so im using some lower performance parts that hurt the ability to cope with higher…
Heathkit SB and HW series frequency meter and CAT signaler – Part 3
CI-V Proof of concept. To test the feasibility of the CI-V communication, I programmed a simple response loop where the program (n1mm) send a frequency request and the program replies…
Heathkit SB and HW series frequency meter and CAT signaler – Part 2
Measurements: To pick up the signals I’ll follow the instructions on the SB-650 user and assembly guide. BFO: The BFO signal is picked at the IF board placing a 220pF…
Heathkit SB and HW series frequency meter and CAT signaler – Part 1
The objective of this project is allowing the Heathkit SB or HW transciever to send the current frequency to a computer, in order to use n1mm or other log programs.…
