[NLRS] 3456 to 3400

[BRUCE WW8II]

Just a passing comment since I no longer have any active equipment for
3400  I  still have a new (bought from PYROJOE) Toshiba UM 2683A RF
amplifier 1- 2 mw in 55 watts + out  if anyone is in need of one,   $125
gets it shipped to you..  : send me an email off list if interested. I
might even have a used one around here somewhere also.  I also
have the large heat sink to mount the amp on  (extra cost) .. any
interest email me  My email is  wa8hgx @gmail.com
