Category:	TEST
Heading:	F.S. RF BROADBAND POWER AMP
Ad Message:	i am selling a broadband 25 watt linear amplifier that requies only Zero dBm input to achieve full power out 10 to 90 MHz CW carrier. This 2-stage, class B linear MOSFET amplifier was designed as a highly linear amplifier by an OEM company for medical imaging. It is re-packeged to contain needed power supplies, a fan and input attenuator. All you need is a good signal generator (or tracking generator) and a 50 ohm load and your ready to go. Great for testing RF filters and power tubes,or maybe for QRP operation. I am asking $200 plus shipping to lower 48 states or local pick-up and save the shipping cost. Copy of schematic is included. i accept cash, check or Postal Money Order. More pictures or information by request, via eMail thru this ad on QTH.COM. Thanks for reading my offer.

Your Response to this Ad:

Due to the amount of non-ham scammers trying to respond to the ads, I am now asking a simple question that ham operators should easily be able to answer, but scammers may not know the answer: What is the number that hams use to represent the phrase "Best Regards"? This number is typically transmitted by hams at the end of a QSO.
Best Regards:
