Last evening while the better half was out, I fired up the rig for some cw practice. The bands were better than the other day! I found a number of signals on 40m so I located a slow QSO and started copying. I was getting % of what they were sending. Calls, QTH, RST, all the important things. About 10 minutes in a loud signal moved in close obliterating the QSO I was copying. I tried to use the inboard filters on my IC751A but they just weren’t enough. I have a 500Hz filter in the first IF and nothing in the second. So…the filter research started.
I put out an email on the 751 Yahoo list. Jarmo OH8KVA replied with a recommendation for an Inrad filter. I looked them up online and OUCH the filter was half of what I paid for my used 751! I would love to have that kind of cash now as I am unemployed. I remembered seeing many discussions on QRP-L about the NESCaf filter kit. With a bit of research and reading I decided that was the way to go. Adjustable center frequency and bandwidth in a kit. Did I mention that the filter kit with the optional connector kit and shipping is only $38? In Congressional economics I just lowered my deficit by $132!
I have got the itch to build something new and this will do nicely. I am considering building it as a part of a multifunction station accessory. I have an un-built Pico keyer kit in the cabinet and I need a new 24 hour clock for the shack and am thinking of brewing my own. Maybe I can find a nice tin to put all of these in and make it a fixture on the shack desk. I am now excited about building and operating again. It’s been a long time!
