The Simpleceiver Plus Project ~ An Ultimate Form of DifX

Return of the Simpleceiver Plus! 9/12/2017 ~ Arduino Sketch Code for the DCRI have posted the code for the Simpleceiver Plus DCR on my website and you can link to it from here I have also copied the complete blog thread on the Simpleceiver Plus DCR to this page so that there is an easy archive of all of the info that is on this blog. The downside is that it takes a long time to load since it is a huge file. But the plus side in the event we have another ghost in the machine with this blog (like losing the comments) the data will not be lost. This will be the last posting to this thread. The next series will be on the conversion to the SSB transceiver. 73's Pete N6QW My Apologies "The Ghost in the Machine" ate the Comments. I have no idea how that happened or how to get them back.7'3's Pete N6QW 9/08/2017 ~ The Arduino/Si5351/Display Wiring The above is a pictorial wiring diagram since some homebrewer's are new to schematic dr…

A New Line of Transceivers ~ DifX

A New Definition of HAM! 8/18/2017 ~ I am surprised and shocked that this post did not raise more issues with the position I took on these various methodologies. It is only my opinion and who is to say I am right (Although I tell my XYL --I am always right!). As a homebrewer, obviously you are encouraged to experiment and learn all you can. But if you are just starting out in "rolling your own" some approaches are a bit more challenging such as curing a drift problem on an Analog VFO. My issues with the Old School VFO is that the how and what you use to build the VFO really drives the "drift issue". Sure a plastic straw for a coil form has allure, charm, is cute and even meets social consciousness objectives in recycling products that may end up in a landfill. BUT that straw could be (and most likely) is on the critical path for a drifting VFO. So try to find a more suitable material that is both mechanically and temperature stable. Ceramic coil forms were the old s…
