[Johnson] T/R relay

[WQ9E at btsnetworks.net]

Hi Jimmy,

I responded to your original post on the AMfone website.  Let me know if you need additional info but the vacuum relay is your best choice for this application AND it MUST be set up for a slight delay on break to avoid flash-over in the RF Deck and/or modulator section.

Please also take note of the instructions about fan lubrication and cleaning before putting your Desk KW into service.
