DS as per my reply to GY3rp you can get pre etched boards for he old Bitx frm Fred at Far Circuits . He also does the 75m? SSB board by Weber which is essentially a Bitx but using? CMOS analogue switch switching.? Latter board is eight USD. BEWaRE you have to source the IF cans for the post mixer filter.? Now hard to get. This latter board can be moved over to 40m I have had that in writing from Weber. Ditch the 9M IF frequency if you use it. Use 10M , much more practical. Maybe 9M IF crystals cab be had in India but try finding them at Reas price in US or Australia.? The Weber PTO VFO.design ie permeabilty tuned . .. I would not go there it looks the work of the devil mechanically . There are much better buffered VFO designs from Ashan? Farhan for example.? On the Weber board the power amp is integrated.? An 2n3866 subs on the driver would make a world of difference to power output.? have a fish around on my other replies as to where to get this cheap (and not fake). Diz the toroid king, or Fred at Far Circuits can supply.? Without this as the driver , the IRF can barely make 2 Watts.? With it it will go closer to 5 W.? before you try to juice up this PCB with more volts than say 13 CHECK ALL the component specs.? I can't remember if Fred splits out the power rail to the IRF510.. if he does then you can do more things. Remember an anti stuff up 2A (say) schottky diode on the power rail. You don't want 12hrs' work down the drain by some fool hooking it up back Ass-wards.
