Hi friends, please I have the complete article in Polish Language of Antek transceiver, and I want to construct it in 40m band with SSB and CW mode, help me please, first pass is substitute the BC211 to 2N2218 how it's possible to make this? My LPF and BPF was modified as in the attached figure. Is possible to modify this IF for 10MHz, example IF 10MHz - 3MHz VFO = 7MHz or not? Do you have a simple side tone circuit to add the CW mode in this circuit? Is possible to add a new Key to select USB or LSB selecting with Xtal 5 in series the inductor 10uH (LSB) or 3-30pF to trimmer (USB) see my attached mod BFO. Help me with suggestions in my VFO with varicap diode BB112 + 10k / 10 turns pot attached here in VFO; TR1 and TR2 I can roll in Ferrite Core FT37-43? How many turns is necessary to roll this core and which size (AWG) is used in TR1 and TR2? Do you have other mods example S-meter and Power Meter etc?
