James, M0VLF, gave a brief talk on the construction of his homebrew antenna tuner for HF.
This has been tested and has showed promising results, and only requires an air spaced coil, tuning capacitor and a rotary switch - the most difficult and expensive part to source is the enclosure itself!
M0SHA has a circuit diagram available for those interested in this easy to build tuner.
Feel free to contact James or Tony for construction / design tips at one of the meetings.
James, with his tuner.
