What kind of relay is used in FT-101 transceiver?
The antenna T/R relay (RL-2) in the FT-101 transceiver originally an OMRON Type MX-2P. This exact part number is no longer available from OMRON in the MX series, however a suitable replacement can be had in using a similar type OMRON relay in the general purpose relay series MY series, see data sheets in pdf format below.
How to identify the pins of a relay?
To identify the pins of relay you want ohmmeter. Ohmmeter is used for measuring the resistivity of an element then we measure the resistance of all pins in relay. The two pins which resistance is low not 0 Ohm it’s round about 300 Ohm to 350 Ohm then these pins are coil pins of relay.
What are the switch connections in a relay?
(Mentioned in the topic “How to use relay example of basic schematic of relay circuit diagram”). Switch connections of relay are mostly named as POLE /COM, normally Close (NC) & normally open (NO):Pole and COM is equal to Common, normally closed and normally open is always connected with the moving part of the switch.
Is there a n4yi fix for the FT-101 T / are relay?
N4YI Relay Fix for RL-1 It’s here! (Zip File 4mb) RL2 is still e conomical and available. The antenna T/R relay (RL-2) in the FT-101 transceiver originally an OMRON Type MX-2P.
What are the resources for an antenna switch?

How can I remote control an antenna switch?
Remote Control of Mast Mounted Equipment – This article presents a method of controlling preamps, antenna switching and polarization switching remotely without the use of control cables.
Why do I need a 5 antenna switch box?
Five Antennas Switch Box- A project of a 5 Antennas Relay Switch Box, all Switches & Relays have both contacts wired in parallel to improve reliability of operation, to prevent static build up, when an antenna is not in use the feeder coax is grounded. [ Hits: 899 | Votes: 1 | Rating: 10 ]
Why do I need an isolation relay for my preamplifier?
There is great advantage to having an “isolation” relay that terminates the input of your preamp into 50 ohms. It provides an evaluation tool. It provides a comfort level when you can see the noise produced by the termination in comparison with cold sky, to tell you that your system is functioning properly.
