1. [CQ-Contest] SDR,DSP,Skimmer....the death of CW contesting (score: 1)

Why? I think because the cheating now is more and more easy thing to do. I can see a station where 50-80% of all QSOs would be done by computer not by a man. The software would scan bands, check call

Peter, It is hard to compare my filters with your design despite the fact that they are very close by circuits. I think we had a different specifications for the design. - I designed BPFs not for a m

Steve,I prefer to have everything separated.Two computers and two keyboards, two set of BPFs etc.,It is more expensive but much easier for station setup when every Radio is fully independent.Personal

John,Such filters should be symmetrical inside.I would measure VSWR from both ends and install filter by lower VSWR to an amplifier....if there is any noticeable difference.I label my BPFs as well wi

Jim, You are absolutely right and there is nothing to add. The BPF can perform at 100% from its specification only being connected to a feed line with a good VSWR. It is always recommended to decreas

Hi, As per Rob Sherwood, NCB measurements, IC-7300 and IC-7610 OVF (overflow) level is -10dBM out of a pass-band signals. It means Triplexer+BPFs set MUST deliver a better than that number to allow
