[ARC5] R-13B control cable/head

Tue Oct 1 20:59:56 EDT 2019

I have a Command Set R-13B receiver (108 - 135 Mc) that I would like to use to monitor local air traffic control communications.  Before I start the process of conversation to 12 volt filaments/heaters I’d like find a control box (and cable) so I can read out the frequency I’m tuning to.  Is there any “extra” ones out there?  Thanks.
