Hi Doc, It is normal for non-reciprocal or unbalanced paths to exist on HF. Local noise level and ionospheric propagation of regional noise level are some of the most common variable leading to it. Add QRM, RFI, and EMI to the list, and you have a wild mix! In fact it is rare that any 3 stations in different locations on the same comm channel, at the same time, experience the same Signal/Noise ! When you combine this with the excellent decoding sensitivity of some digi techniques compared to the lesser decoding of another mode sharing the same communication channel, it is quite easy for there to be a non-reciprocal interference situation in the shared Amateur Radio HF bands, even with similar power levels on all stations. In my opinion, these peculiarities, and also the uncertainties of propagation, are some of the most interesting things that are exciting about operating HF! Bonnie KQ6XA Need a Digital mode QSO?
