 TEST - F.S. BROADBAND 25W RF AMP
i am selling a broadband 25 watt linear amplifier that requies only Zero dBm input to achieve full power out bandwidth from 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.

 RADIOHF - Heath SB-1400 HF Transceiver For Sale  

Heath SB-1400 HF Transceiver For Sale:
-
This is one of the last radios Heath made
and they didn't even make it! It's actually
a Yaesu FT-747 clone.
-
It came all assembled -- not as a kit -- so
no worries about bad solder joints done by
someone without soldering experience!
-
It is a relatively easy to use rig, ideal
for beginners and old timers alike. Even
though easy to use, it is loaded with crystal
filters. It has a 500 hz filter for narrow CW,
a 2400 Hz filter for SSB, and a 6000 Hz filter
for AM.
-
It needs 13 V DC at about 20 amps.
-
This one works as it should, producing just
over 100 watts out on all bands 80 thru 10
meters, including the WARC bands. Cosmetically
it looks fine.
-
Buy this rig with manual for only $300 plus
shipping from Florida.
-
Thanks. 73,
