In addition to mounting all but the inductors and transformers for 80m the Warbler and a few more components for the 40m WSPR Warbler I have built a RockMite 30, for use as a Grabber RX only for 30m.
The evening welt with getting the Local oscillator (10.140MHz Xtal) down to 10.138.700. This is done by bypassing the frequency switching, using a simple serial connection of a 10uH inductor and a variable capacitance ( 12 - 30pF ).
The input Xtal filter will be added later, after stability test of the local oscillator, and will probably be a simple SIngle Xtal tunable filter.
Tomorrow will be busy with some non radio activities, so progress will be much slower than it has been this week end.
FT8 it's a winner! - 28 MHz FT8 mode last night open to VO1NE GN27 S.A. PY LU CX CE good signals after repairing the wire antennas damaged in the storm last week 80m...
