Help with setting up the relay!

Anton

Good afternoon! I use a USb relay to control the antenna switch. Please tell me how to write the frequency boundaries correctly so that everything works? I tried different formats, but it doesn't work. The relay does not turn on when the frequency changes. I want to make sub-ranges for CW and SSB. I may not be writing the frequency format correctly in the graphs in the screenshot.

type in the frequency in Mhz in LO and HI. Like 1.8 for low and 30.0 for high

Make sure you turn off the DISABLED button on the left.

Adjust SOURCE to what ever it need to be,

Anton

I did as you said, but nothing happens. The relay at a frequency of 3.5-3.6 MHz does not turn on

Hi Anton, how do you have your bit cable wired to the relay board? In your example, slice A needs to be between 3.5 and 3.6 MHz for bit line 1 (i.e. the second line) to change state to a high state.

If the relay expects to be grounded to to activate it, change the polarity to Active Low.

This works for me. Relay 0 is active below 10Mhz and relay 1 is active when I go into TX

KD0RC

Hi Mike, did you mean:

Relay 1 is active below 10Mhz and relay 0 is active when I go into TX

Or am I missing how the PTT On/Off button works?

Mike-VA3MW

I think I said it correctly.

Relay 0 has +12 on the NC contacts. When the radio goes into TX, the +12 is removed as this relay is now active. This removes the 12V from the Active Antenna and that causes the antenna to be grounded as well to protect the preamp in the active antenna.

Relay 1 is wired in series with Relay 0 and provides power to the active antenna when below 10Mhz.

KD0RC

Ah, got it.

Anton

Doesn't want to work with such settings. Checked 2 different relay boards. The board itself is connected to Flex. Here is a screenshot. I need 6 relays to be additionally connected at a frequency of 3.5 to 3.6 MHz.

you have band and frequency range both being used. Try changing everything to frequency range instead of band. Example - 20 meters 14.0 - 14.350

@Anton That should work. You may want to consider resetting the radio.

If you change Active High to Active Low, you should hear the relay change. If you don't then it might be a bad relay board.

If it is the SainSmart board, you are required to supply 12V to the board too.

Anton

Mike, I can hear the relay activating when I press the button. and when I set the radio to turn on the red light on each range, everything works too. Of course I supply 12 volts to the board. Everything works for me, except that it doesn’t work when I set the frequency limits... I just can’t find a solution.

Do you have 12V external power connected to it?

Anton

Certainly. After all, when I display only the ranges, everything switches and works. but does not work only when specifying frequency boundaries. there is no reaction when I set the settings as shown in the screenshot

Do the log files show any communication between the radio and the device?

Highlight the Relay Board and then click Log.

Now, test. When you change bands, does the radio send a command to the board? If yes, then the board is defective. If no, then you have a radio issue.
