Farhan,
Really looking forward to building the uBITX and am in the process of gathering together all of the components.? Also going to go SMD as you did. ?I have a
few questions from studying your written description and the picture.
?
1.? ? ? ??1. ?The picture appears to show four relays and I
only count three in the schematic.
2.??????
?2. ?The picture appears to show seven crystals in
the 12 MHz filter and the schematic shows eight.
3.??????
?3. ?I can¡¯t figure out the function of the P2
connection that comes off of the K3 relay, pin 12
?
I know I am probably missing obvious answers but just can¡¯t
figure it out.
?
Planning to use the K7QO ¡°Muppet¡± pcb technique for
construction, breaking the design into small modules (about 16 in all), and
place them on a 6¡± x 6¡± so pcb as you did.?
Going to go at it slow and test out each module as much as my knowledge
and test equipment will allow.? I have
the PHSNA (Poor Ham¡¯s SNA) to check out the filters and will work on a way to
test the amps.
?
Thank you so much for your design !
