[Fox_Tango] Yaesu FT-101's

[Al - NW2M]

Chris,

The output should fall slightly as you go up in frequency.  CB'ers most
likely ran more than 30 watts of carrier on AM which is really 120 watts
of RF envelope.  This may be a "cooked" FT-101 radio.  Normal power
output in the TUNE mode is in the 100 watt range.  Most wattmeters can
have a 10% error, so it is easy to have a +/- 10 watt reading into a
dummy load on a 100 watt scale.  You cannot measure power for AM, SSB,
or CW the same way.  Even Yaesu lists power as Input power, not Output
power.  Same with their FL2100 linear amplifiers.  This is why CB radio
has 4 watts on AM and 12 watts PEP on SSB.  

The FT-101E is missing the ACCY jack on the rear of the unit.  Pins 1&2
need to be jumpered together to light the tubes.  For now, just use a
jumper wire 3/4" in length.  This is a very common mistake with new
users.  No worries!

Also, get copies of the user manuals.  This is all explained.  Also
search www.google.com for parts and ideas.

Keep an eye open on Ebay for FT-101 parts.  New crystals can be up to
$20 bucks each!

Best of 73,
