Tuning the HF Transmitter the Easy Way

January 24, 2018

I recently saw where a new ham operator was questioning how one tunes a HF transmitter that does not have a built in meter in the output circuit.  He was referring to the Pastime Projects 6V6 transmitter kits but the question would apply to similar low to medium power transmitters.

One easy and cheap way is to use a CB Field strength /SWR/power meter.  If you check the specifications, you will find these meters will work just fine on all HF frequencies from 160 to 10 meters and beyond. Many are listed at safe power ratings of 10 to 1000 watts of output power.  And, they sell for $30.00 or less (much less) on eBay!  Ideal for experimenting and measuring our HF transmitter kits performance with almost lab rating results for low surplus prices.

Simplest way to use the meter is as a field strength meter.  The meter will have a hole for a short wire antenna to attach.  (Make sure the wire antenna you use has some kind of top on it to prevent injury to an eye!)  With the meter near your transmitter – but not electrically attached – try transmitting into an antenna and tune your FSM for maximum strength.  The meter follows the strength of the transmitter, so tuning for maximum should get you great results.

Good luck!  Always get help from your local club when you can.  A good experienced radio amateur is always a friend to have.  73 Glenn .. for Pastime Projects.

SPECIAL DEAL ON 6V6 MC 80 M PASTIME PROJECTS TRANSMITTER KIT

August 9, 2016

Today we are offering a special on our pastime projects 6V6 MC 80 Kit. This kit includes a wound and tested
Output plug in coil tested on 80 meters in our shop. In addition, we will include a new 3.5795 crystal element assembled in a FT-243 or similar style vintage type crystal holder. These are assembled and tested here, both
on a communications monitor and in a completed 6V6MC 80 Kit. These crystals are performing well for us in the
lab here at Pastime Projects, especially using our QRP mode power supply at 200 volts. The crystals have been
tested at 350 VDC with good results, but we are not ready to warranty the crystals at this time. For a limited
time we will also offer free shipping within the US. Delivery may run a little longer depending on demand,
but we are starting to build stock in advance of orders. 73 best wishes Glenn Brown for http://www.pastimeprojects.com and pastimeprojects(at)yahoo(dot)com.

12K5 OSCILLATOR KIT PRICE INCREASE

June 8, 2016

After 10 years of production our little 40 meter do it yourself code practice oscillator kit faces a price increase.  We recently looked at our costs in today’s market as compared to what we paid in 2006.  The increase is effective immediately. You will still get the same pre-wound coil, a new qrp style crystal, and the detailed instruction manual we have strived to improve over the years.  While this is considered a “transmitter” kit, we very
plainly describe its communication ability as “most likely won’t be heard next door”. You kit builders know that it’s still a thrill to follow instructions and build something yourself.

Remember When QRP 40 M transmitter

Happy Building!  73 Glenn for Pastime Projects   pastimeprojects(at)yahoo(dot)com
