Newbie here.....i bought some bitx 4 band boards from pcbway......Mr.?Wahyu Hidayanto says the board is essentially a bitx20 with of course some on-board band pass filters.?
I was looking for the BOM for this board..........or assume as Mr. Hidayanto says...........use the bitx20 BOM and the:
80M
L1 = L2 = 2.2uH
L3 = 4.7uH
C1 = C2 = 1.5nF
C3 = 680pF
?
40M
L1 = L2 = 1uH
L3 = 2.2uH
C1 = C2 = 820pF
C3 = 390pF
?
20M / 30M
L1 = L2 = 0.47uH
L3 = 1uH
C1 = C2 = 390pF
C3 = 180pF
?
15M / 17M / 10M
L1 = L2 = 0.33uH
L3 = 0.68uH
C1 = C2 = 180pF
C3 = 82pF
I assume i am on the right path?
How anyone built one of these?
Thank you for putting up with? fast learning newbie.
