I have found, after assembling and setting up my K2, that the Iambic
setting is stuck on 'B' keying and cannot be changed.
To explain further: switching between 'A' mode and 'B' mode or the other
way has no effect. The keying is always 'B' and the two modes are
definitely the same. Either that or there is only microsecond
differences and I can't tell.
What is certain is that the mode it is stuck in is the same as my MFJ
422B (modified to be switchable) in 'B' mode and I can certainly tell
the difference between modes in the Curtis chip on this keyer.
I am wondering, as this is done in firmware, if there is a solder bridge
between 2 IC pins, thus preventing the switching of modes, or if there
could be a firmware error?
Or is the difference extremely subtle?
Thanks
