Hi Dick,
If you're lucky enough to be able to install a receiving antenna about 1000 feet from your transmitting antenna, a separate high dynamic range receiver or transceiver will be able to hear weak signals when the main transceiver is calling CQ or working QSOs. In band receive allows SO2R operation in 160 contests. I borrow my neighbors 4 acre field during the winter for my in-band receiving antennas. They work great with either my K3 or FTdx5000 for in-band receiving with my transmitting antennas 1000 feet North of the receive antennas. 73 Frank W3LPL ----- Original Message ----- From: "Dick Bingham" <[email protected]> To: [email protected] Sent: Thursday, August 20, 2020 6:30:08 PM Subject: "good in-band receiving capability."

Message-ID: < [email protected] > Content-Type: text/plain; charset=utf-8 Hi Ron, 700-1200 foot spacing should provide good in-band receiving capability . SDR receivers won't work for in-band receive, you must use a traditional transceiver such as the K3, K4HD, FTdx5000, IC-7800 etc. " I do not understand what "In Band Receiving" may be. When I TX my receiver is in effect 'off' but listening on channel or tuning +/- my TX frequency (say a DX station in a pile-up.) What is being discussed when " good in-band receiving capability " is mentioned? 73 Dick/w7wkr at CN98pi _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
