SDR MW Filter with free worldwide shipping

Designed by John Futter ZL2J, this bandstop filter attenuates signals in the MW band 500kHz to 1.5MHz for locations that have very high levels from a nearby broadcast station. It is bandstop, not high pass so the VLF band is unaffected.

The circuit is covered in clear heatshrink for physical protection.

Due to recent global shipping rule changes we can no longer post these from New Zealand without a formal customs export entry which costs more than these products are  worth. 

So as crazy as it sounds we are now bulk shipping them to a China based logistics company who ship them globally. This adds a couple of dollars to the price but includes pre paying global duties/taxes/tariffs. This is called Delivered Duty Paid (DDP).

The logistics company  delivery times are much faster (5-10 days) than the ordinary letter post we were using and includes online tracking. The service is way better than the snail mail we were using. Some previously took up to two months and there was no tracking.
