<html><div style='background-color:'><DIV class=RTE>I've got an Alinco DX70 HF rig that use for a portable station. The DX-70 is a small and inexpensive HF-6M 100 watt transceiver. I've had a lot of fun with it but it would be nice to upgrade the stock ceramic filters with crystal filters. I don't know if there is room for this, or even how practical this might be. I know there are lots of these radios around, does anyone know if any crystal filter upgrades have been tried?</DIV>
