One Letter Change Makes for a Whole New Meaning. 7-30-2019. Some more rig photos added. I recently said I have built about three dozen homebrew SSB Transceivers --this is just a sampling. That number might be low if you count all the way back to 1970! If any ham has built more than this number of homebrew rigs --let me know. n6qwradiogenius@gmail.com 8-1-2019 This compilation is missing three rig photos including the Belthorn III and the Breadboard SSB. Also missing is the original ZL2CTM SDR XCVR. I think we are beyond 36. In the background I am working on a new SSB Transceiver that will use the really "old technology" -- a crystal filter. Don't get too excited just yet, as the project is a way off.  But noteworthy it appears my SDR adventures have left many uninterested in moving to the new state of the art -- that is OK too. Too bad though as it really is the new wave. Our hobby has a very large tent to accommodate the many interests.  Yes...

Some New Data ~ Data Points Here is some setup and reference data for the RADIG. Today I looked at both the design of the J310 Amp stage and the drive levels from the Si570 on all bands.   Starting first with the drive levels. I put a scope on the output from the pot as it connects to the LO Port on the  ADE-1 and the results are a bit surprising. Keep in mind that the actual frequency being generated is 4X the operating frequency. So at 10 Meters the RF from the Si570 is around 120 MHz.  160M ~ 544 MV PTP 80M ~ 544 MV PTP 60M ~ 544 MV PTP 40M ~ 544 MV PTP 30M ~ 544 MV PTP 20M ~ 544 MV PTP 17M ~ 512 MV PTP 15M ~ 472 MV PTP 12M ~ 377 MV PTP 10M ~ 320 MV PTP The outputs below 15 Meters were nice square waves and the surprise was that the lack of sensitivity would most likely only occur on 12 and 10 Meters. Thus my observation of lack of sensitivity previously on 20 Meters was more likely driven by the J310 Amp stage and not th...

Loading the RPi3 with QUISK I have been working on three webpages that detail how to setup the Raspberry Pi3B (also the ASUS Tinker Board) for operation with QUISK and you can see that by visiting my new website. See http://n6qwradiogenius.us Of particular interest to the RADIG project is how to load the RPi3 and QUISK found at the first link below http://www.n6qwradiogenius.us/Load_Quisk.html This is a bit tedious but covers setting up the NOOBS on the RPi3B and then how to setup the QUISK Software. But the real meat is how to do the actual setup of the parameters within QUISK so it plays with your RADIG which is the second link of the three links.  For that piece, I will make a video so you can see step by step how to enter data on your configuration. If I were to simply describe it in words -- you would get lost (very likely I would get lost). But the video should help. Give me a couple of days -- I want to script it rather than wing it! Also keep in min...
