Grabber RX back to DSB

Due to reduced sensitivity, the filter-crystal is back out again. Consideration here: we are looking at a bandwidth of 100Hz. The received LSB will be (about) 10135100Hz to 10135200Hz. According to this document, there is just the occasional Feldhell QSO, but other than that, the LSB range of the DSB receiver seems to be an empty spot.
