Re: End Fed antennas w/ uBITX #ubitx
Hi Allison, these 1:49 transformers are just conventional transformers. Would you think that a 1:4 and a 1:9 current (not the voltage ones) transmission line transformers in series to get a ratio 1:36

Re: Front Panel Stereo Socket Board Wiring Layout
If one has working MICs meant for other rigs that he uses, we can by a similar connector and wire accordingly . It helps sharing the same mic for ubitx. regards sarma vu3zmv

Re: Front Panel Stereo Socket Board Wiring Layout
There really is no "standard" for wiring mic connectors. Each brand seems to have their own scheme. Unless you are trying to match a mic from an existing radio, just wire it so it makes sense to you.

Re: 12MHz xtals and QER Filter
Rahul, Parallel caps also offer lower ESR best is the values are near the same but it helps. The biggest is crystals ground for series resonance vs parallel.? IT seems to get me a lower ESR and Lm.
