This has been discussed at length in the SDR groups. Upon many recommendations, I invested in a DX Engineering DXE-RG-5000 Receiver Guard to protect my SDR (SDRPlay 2). It is a small box with BNC input and output connectors. It is rated for 500 kHz - 150 MHz and clamps the received signal to 0 dBm, well within the specs of any modern receiver front end. Note, however, that it cannot pass any transmit-level RF and there are copious warnings to not transmit through the device. It requires either a separate receive antenna, a separate T/R controlled antenna switch, or a rig that has RX-ANT-IN an RX-ANT-OUT capability. The instruction manual has many diagrams covering each of those situations. (I am not associated with DX Engineering, just a satisfied customer.) 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
