Re: LF: JT9 on LF

[Chris Wilson <dead.fets@gmail.com>]

Hello Stefan,

Just  seen  this, sorry. I am happy to try and retune the loading coil
to  137.4,  my  only  issue  is I have no quick and easy way to change
between  TX  and  RX  as  I am sing the same antenna for both. The U3S
looks  a bit kludgy for both RX and TX. Is there any point me trying a
few TX's tonight, without being able to see any reception save via the
web site? Thanks.
