For TX I would only use toroids or air wound coils. For RX you could use radial or SMD. The Q might be better with toroids, although.

I built a QRP version for my 49-er that works quite well.
At QRP levels is there an advantage or disadvantage to using wound toriods versus radial inductors (or even SMD), especially on the receive side?
