Books About Radio listening in the USA

"Something in the Air"  by Marc Fisher

Lots of good stories about the development of music and radio's Rock and Roll era through the 90's.  Easy to read and in a humorous style.

Early radio broadcasting in America in the 20's and 30's.  Lots of good history of radio and the country during this period.

Listening In  by Susan Douglas

More of a sociological treatment than the others AND talks a LOT about hams as an influence on early radio.

Managed some hours on the WPX RTTY this year and made a few contacts.  Was able to hold a frequency and run quite a bit more than is 'normal' for my small station.  On Sunday the last 4-5 hours was mostly 'running'.  The N1MM program was working except the band map was not filling with spots for some reason.  The station used was Cushcraft R7 vertical, MK V and Alpha 78.

DX highlight was working the S9 Sao Tome and Principe.  S9DX Homepage

ATS-4a Ready to test Now Finished

ATS-4a is now finished and fully operational.  The audio coupling Cap C55 was a problem that I solved by putting an additional .1uf in parallel with the existing cap.  Some folks have suggested swapping C55 and C61.  In any case it seems that C55 needs to be larger in value for the audio chain to provide adequate output.  At this point I am getting about three watts output at 12V with a weak 9V battery in the Oak Hills QRP Wattmeter into a dummy load.

ATS-4 Finished

Today the missing (lost) 'Red' SMD Cap came in the mail.  The last component was added and the unit was inspected and looks ready for final assembly and testing.

Thanks for this group and thanks Steve for nice job.
Now Built my small nice ATS4 A. Good CW tone , Pout 5-6W and only 15 m 4W. Good RX.
Not used liquid flux for switches, C55 really 1.0 uF, C46 0.01 uf
BS170, 2N7002 careful to do solder - not good for static
