Cross Country Wireless have started making their range of RF filters and diplexers again after a break following the launch of their SDR-4+ receiver.
The RF filters include bandpass filters for 50, 70, 144 and 432 MHz, 144/432 MHz dual band filters and a double notch 144 MHz filter notching the UK paging frequencies.
The 144/432 MHz dual band filter is particularly useful with Yaesu/ Icom/ Kenwood dual band mobiles cutting out interference from and to local broadcast, TV, GSM and other amateur band signals.
The diplexers available are 50/70 MHz and 144/432 MHz.
Filters are £58.50 plus £5.00 post and packing.
Diplexers are £63.00 plus £5.00 post and packing.
More details including actual test sheets of recent filters and diplexers are available on their web site - http://www.crosscountrywireless.net/filter.htm
