ICOM IC-738 Remote Control of Antenna Switch WN8P on 10/7/20
Is there a way to remotely control the ANTenna port switch? I would like to transmit using ANT(2) port and receive using the ANT(1) port. The purpose is for use of VHF and UHF transverters so I would not have to have switching in the transverters themselves.

Digi-Key offers to pay for shipping (and insurance) if you submit your order like the old mail order method. That is you send a check or money order to "prepay" for your parts and they will ship using their choice of shipper.

Hi Bill, this is Larry.
Part 97.201(b) as Part 97.205(b) is what frequencies the station may operate on. The local repeater association, of which I am the vice president, is putting forth an effort and spending some money on implementing auxiliary control to turn the (2 m) repeater off (and back on again) due to whatever reason. This controller function can be done by telephone line, internet connection, or radio link. If by radio link what frequency is dictated to be used?

Would someone please point me to the Part 97 rules for repeater control, that if done by radio the frequency used must be greater than 220 MHz?

Is there a spectrum inversion that takes place when using a quadrature sampling detector (Tayloe detector)?
