Intermittent Power all band
Intermittent power all HF band, but RX working well.
Under test the power dropping down frequently, opened the radio i found a bad ceramic filter FL2 on the logic board corresponding at the TX line.
I have purchased a new ceramic filter but the original MURATA CFWLA450KEFA-B0.
After repaired it the Argonaut V working very well giving 20w out!
