Thank you gentlemen. It will be fun all around building the 30B and it’ll be stretched out a little to prolong the good time, since I have to order and wait for cone-shaped new solder iron tips.
It all started yesterday when the manual PDF arrived by e-mail and I started printing it out. Today I completed the printing and have been making observations from the manual.
Since the circuit is based around the FM25B, a long-standing Ramsey favorite, I have been comparing the schematics, and see many aspects common to both. But the big thing about the 30B is that all settings are controllable from a front panel, and to make this happen there are several chips not found in the 25B.
The Low Power Hour will be covering the project for Episode # 101 and pictures will be taken along the way to share here on the site.
FCC rule zealots can take comfort in the fact that Rule 15.15(c) will be applied to this transmitter once the testing period is over… “The parties responsible for equipment compliance are encouraged to employ the minimum field strength necessary for communications.” Yes sir, it will be turned way below legal level for broadcast in a 10-foot area.
Now get some sleep.
