HI Bruce: I did have one 28-209 back then and was on the air for 3 year with no issues even when i found snow on the unit it still ran like a timex watch.
Did you check your mike to see if it was good,There kind of cheap.
And on the 1 transistor in front closes to edge 2SB54 you had to bend the center leg backward if you didn’t use a shrink tubing on that center leg you would have an easy short against the other 2 legs as well across the transistor body which would cause your issue.
I even found sometime if you did not have a good tight connection with them springs you would have an issue as well.
when i was on the air i did live shows and got about 3 miles out in some area only using a antenna with no ground and the antenna was up about 20 feet in the air.
The radio i used for picking the station up was a General Electric 3-5280B and the audio quality sound very good was on 1610 am.
as the kit goes i have 3 here it was my very first am station on the air and my fm was a mr. microphone.
The good old days. Station 8
