Idea: use online tools to translate DX ham radio magazines ?
An idea struck me (don't worry, didn't get hurt, it doesn't happen that often :) use an online text recognition and translation tool to translate some of the articles from DX ham radio magazines. In particular, the CQ Ham Radio magazines from Japan that I have. I used to go to a Japanese mall in suburban Chicago which had a bookstore. They sold all kinds of Japanese magazines including CQ Ham Radio. They are pretty expensive even with a subscription due to the high shipping costs. The earliest issue I have is from October 1993, over 544 pages of articles, news, columns and ads.
I had previously blogged about using online translators to figure out the writing on the Terryscope:

Here is the site I usually use:
https://translate.yandex.co.il/ocr
The first candidate for translation was a brief construction article from that Oct1993 issue: an automagic notch filter which does NOT use DSP. This brief article by JR0LJN uses the old MF-10 (aka LMF100) as a notch filter tunable via the LM565 PLL with a 74HC390 counter to divide the MF-10 100x clock to audio range. Not sure what happens when there are multiple carriers, maybe then it's time for a diode detector ? :)
Notch filtering is handy for trying to listen to tube AM stations with an SSB radio.
The source and translations are presented here:
first page of article |
second page of article |
first column untranslated |
first column translated |
second column untranslated |
second column translated |
third column untranslated |
third column translated |
The translation is certainly better than nothing but imperfect :) I will have to see if I can round up the parts and give the circuit a try.
