The links were to worldradiohistory.org
This site has a perfectly enormous collection of stuff on it .? I suggest exploring.? QST is on the ARRL site but I believe one must be a member to access the archive.

Hi Richard ?and friends too

I don¡¯t know where they reside other than somewhere in the clouds. ?I just put ¡°qst 1946¡± into google and that¡¯s what I got ¡­Oct came first and amazing there was the 42. Just lucky for once, or google knew I was going to look inside for a Halli 42 ?due to a flurry of previous requests

I did not look in detail in Dec issue ; Ilooked only about july to dec 46? ,, no doubt there is more in 47 but if found? what I wanted

The QST early pics have the R-42 , not the pm-23 that somebody Steve? Said was in radio news.

I thought QST was part of ARRL and ?i almost signed up to ARRL, a while back but they demanded to know more than the government and ?all the banks and the depth of my pants pockets ! ?¡­So I hit the top right X

?

I will sneak this in here, but my understanding is that it receives AM , and CW all the way to the top, leaving a question, I guess a mode switch must be able to direct 88.1 Mc to either 10.7 Mc fm or 455 kc AM/cw ..dunno yet

?

The last one has 8 pages on the receiver and I didn't count but at least 30 cooperative dealer ads featuring it.? Hallicrafters was really pushing it.??

BTW a really thick edition

? A reaction to war time restrictions.? ?Also note the prices and compare them in about a year?

? With the elimination of ear time regulations the inflation makes our current problem look miniscule.?

Also,? am I imagining it or are these scans better than those on the ARRL. Site?
