Airband 10.7 AM IF
It's weekend...so... relax....
Done this board during the morning and it's still not finished (give me a break, it's weekend) but you get the idea.
455Khz filter was salvage from a Chinese store radio but it's too wide, will try in the future buy one better for the job, never the less it works. IC is a TDA1072 and schematic is similar to the datasheet (http://www.nxp.com/acrobat_download/datasheets/TDA1072AT_CNV_2.pdf) excepto on the 455Khz IF transformer that was "removed".
Now it's just a mater of small details and I can put the receiver on the shack. Anyhow I am allready thinking on adding an 10.7 ssb IF and one for FM (any ideias on a simple 10.7 FM IF without the MC3362 ?)
