I quick look at the AE marketplace reveals ample supplies of 4MHz crystals.? That with a 2-to-2.2MHz VFO would tune it down to the 160M band.? There is also a 4.433MHz HC-49s crystal offer, but 3x pricier.? But it would raise the VFO frequency up to 2.433-to-2.633 and further away from the 160M band.? Howard, n3fel
