[SJRA-Members] SJRA QRP TRANSMITTER PROJECT

[Mario Dianora]

Hello fellow SJRA members,



Last night I made a presentation of the QRP transmitter, which is a 
follow-on to the receiver project we did a year ago.   


The main points to know are:


*  4-5w output on the 40m CW band.


*  The kit includes a crystal for 7030 Khz  and one for 7040 Khz
and has a VXO to allow you to swing the crystals about 3 Khz. 


*  Class E final for very high efficiency


*  Includes QSK (break-in) with ant. switching relay between
    Rx and Tx.   Also provides Rx muting so you can monitor
   your keying through your own receiver 


*  Package includes  commercial enclosure (by TenTec)


*  Complete price $30 if you get in on this BUILD.   After the
   first BUILD,  additional components will cost more due to not
   getting quantity discounts from parts vendors.


*   This project is a little simpler than the receiver,  and there are
     no difficult construction items to build.


*  You will need to obtain 12V at about 500ma dc to run the rig.  
    It will run fine on batteries if you don't have a DC supply.  Even a 
    12V  1 amp wall-wart could be used.  




IF YOU WANT TO BE ADDED TO THE 20 PEOPLE WHO ARE ON THE 1ST BUILD,
SEND ME A REPLY IN THE NEXT WEEK SO I CAN GET THE PARTS ORDERING DONE .


When we have all these radios done, maybe we could have some kind of a CW party
on the air!








Thanks and 73,
