[VHFcontesting] 222MHZ Transverters

[John D'Ausilio]

You can easily jumper the XV so that the LO remains on at all times
that power is available on the connector .. I don't remember it's
designator, but it's 5 pin block with multiple options (I can look it
up if you have trouble finding it).
The heat is a problem for sure .. I've experienced issues on 2M during
band openings when it sees heavy use .. planning on putting a fan to
blow over all four transverters (I have mine in a stack using a custom
bracket)
