Lash up Direct Conversion Receiver

[Skywave]

Any comments/suggestions welcome.

Two:
(1) the R.F. choke in the anode of the R.F. amp.: I wouldn't do that. Why? Because the capacity of that choke will resonate with its inductance and create a tuned cct. at some frequency: this may affect the performance of the R.F. amp.; probably adversely. I would have connected L3 in the anode cct and used L4 as the feed to the control grid of the converter.
(2) You've used a triode for an R.F. amp. Isn't that inviting instability, not to mention an undesirable loading on its input L/C cct.? (Miller effect). Would not a pentode or cascode triode pair have been a better choice?

Just two thoughts; not criticisms.
