Turn a Talking House transmitter into a Carrier Current unit? This just might be possible with a new group of linear amplifiers turning up on ebay.
Surfing the world's biggest digital garage sale sometimes pays off. We'll see if this latest discovery
New low power linear amplifiers from China have the potential to give recreational broadcasters in the AM band the same boost FM folks have had for years.
Until now, a low power amplifier for the AM band was a tedious home build featuring multiple hand wound toroids. Most of us took a pass on that.
Unlike past amp circuits that needed the more complex dual polarity power supply, these new units will run on a simple, single polarity 12 - 15 volt DC supply.
Over the past few months, more and more of these units have been appearing on ebay so if you give one a try, let us know how it works for you!
Currently, these are only available from China mainland and Hong Kong based vendors and that probably won't change anytime soon. If you decide to make a purchase from a mainland source, be prepared to wait three to four weeks for delivery. Hong Kong orders usually move a little faster.
An off-the-shelf solution to a small power boost would be a welcome addition to AM band experimental and recreational broadcasting!
