Farhan,

Look the traces for the final to the output transformer.? Make them wide (low impedance).
same for the gate.?

The interaction between the mosfets and the drivers is both closeness the three toroids try to couple
being very close.? I found that alternating them front and back tamed it so its a space issue.
From the output to kT1 (filter select) get close to the driver and pre driver.? All of the relays in
mine are now wrapped win copper tape and grounded.? Isolation improved and the unwanted
regeneration(TX) is helped.

Running with grounded (and insulated heatsinks) helps also with feedback issues.

The 45mhz amp is tepid, the 2n3904s (q10 and 20 in the V3 schematic) are not doing well at 45mhz?
just the common emitter stage as the emitter followers are fine there.? Changing them to BF106
(handy but other high FT parts should work) brought the stage gain to calculated rather than
about measured 7db.? The 2n3904 is an inexpensive workhorse part but the -3db gain corner
is 15mhz in a 16db feedback amp (TIA helps a tad).
