Has anybody used this unit ? It's unique in that it does not require a separate noise sense ant. It's made by SV3ORA. It can also be installed in the RX only loop, commonly used in most xcvr's. Then it can be used safely, and also used with QSK. It has a separate bandswitch...'marked 'IMD'. The unit covers 1.6 to over 70- mhz......and everything in between. It can also be modified for use on the 2 x lower freq bands. http://www.qrp.gr/nr1/sv3ora_NR-1_Antenna_Noise_Blanker_manual_EN.pdf http://qrp.gr/nr1/ _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector |
