Interesting test on alternative band trials
Posted: 08 May 2022, 00:40
I have virgin RF boards from JclPcb and started testings - mount the all bands path components and start with 10M in K1 -- i figured out the values with the chart from dl2man and fron usdx sandwitch rf board for toroid. Here i need to advise that the condensor-diodes-resistances are from aliexpress and cannot be sure that is no fake components, because of my limited budget i have to have some faith in them.
Ok now: when testing 10M after tuning L12 for second harmonic on 10M i made some eff test in a dummy load at 12V. I was in classic mode and got these results firts in classic and second in HI mode
Looks that i found values for 12M.Next step will be trying the same values at K2 for 12M it may varies, as i read from Manuel the placement on board may change values but i will go with the same at first and bring back the results here. I note that the eff is not high for now but i will keep in the same direction for now and work on that after.With what i have in hands it is good for me. Here are the values used for 10M.Note that the 0 value i think is because the HI mode is present and not allowing the 12M freq in 10M range.
