 No QSL card made yet. But gladly accept UR QSL card, except via Bureau.   Hobbies -- Electronics, Ham Radio.   Born circa 1970.  Has been Ham Since 1983.

I work as contract engineer for small companies do not need full time engineer, or companies who need temporary/part time worker.  mostly  RF design below 1000 MHz, PCB layout, firmware programming with C. experience with designing to pass FCC parts 15, 95, 97 devices.  Rate is around $25 / hr.

Detail of Projects I have done.

YAESU  FT-450D  HF RADIO 100 WTS  AND KENT ENGINEER STRAIGHT KEY.

    

 

 

 

I used to have 300 watts MFJ tuner, but it arched inside, when try to tune 1.8 MHz , 3.5 MHz band with 100 watts RF power with much shorter than 1/4 wave length wire.

MFJ-962D ( higher power version )  seems to work well with any length of wire at 100 watts RF level in any Band.

I also noticed wire diameter does not have to be very large, I used 22 or 24 AWG.

I think it is important to feed End Fed Wire with Current Balun, and Feed point to be close as possible as Good ground such as water pipe.   

Advantage of End Fed Wire is easy hide.

Suction Mount for Temporary use.  Since, it does NOT have good ground, must be used with Half Wave Antenna. Half Wave design antenna, such as MFJ-1412 does not require good ground plane.

Value of Broken Radio :

today's electronics including HAM RADIO rig are getting cheaper and cheaper, in many of the radio specially in low priced radios are no longer economically suitable to repair them.  Most of the electronics repair shop charges $50 to over $100 a hour, and just labor cost alone often exceed value of the broken radios. This makes many of broken radio worthless.  Only way to work around is to repair own radio, so cost of labor is free.

===================================================================

Cost of Living in Rural America is much less expensive compare to larger cities.

 

I have discovered, people in Utah , their culture are quite different from rest of America. 

I will say, their personality are milder compare to rest of America.   Perhaps more similar to Japanese culture in some sense.

so I am very comfortable in Utah society much more so than rest of American society.
