I picked up a used Q5 432-452 mhz transverter. I've been scratching my head trying to get it connected properly. Its for 28 mhz transverted. My model has a common shared IF port and a Ant.TX port.
I tried connecting the IF to the transverter sma port and then the dac port. Enabled in Band Manager but no luck.
It seems the transverter software is as yet incomplete as there is no choice to pick between khz and mhz in the repeater tab. I need a 5 mhz offset and khz is the only choice.
I'm a newb HAM and would appreciate any suggestions you all might have.

What radio do you have? See my GitHub issue about MB1 and transverters.

So then you are going to use the transverter port on your MB1. As you can see from my GitHub issue it’s not working at the moment, but I’ve been in contact with Roman and he says they are clearing out bugs as soon as they can. So let’s hope they prioritize this one!

I’m only using my MB1 for weak signal DX’ing on 2m (and hopefully with a 23cm transverter soon) so I have not tried using the repeater offsets. But as far as I know it should work properly. N8SDR made a video about using repeaters, you might want to have a look:

Thank you very much Hans. I have watched that video as I have most of Rick videos. Hopefully the Esdr3 program will be available soon with the necessary ports and screens active and working. I am able to use on 2 meters with offsets and PL codes working as they should. I will use my 705 or HT until then.

Any common IF transverter will do the trick. I would personally recommend transverters from Q5, Kuhne or HA1YA. But as you can see, transverters are not working yet in ESDR3, so I would not buy anything until it is fixed. I have several transverters from Q5 and HA1YA, they are great. Using them today with my Flex, but would like to move a few over to my MB1.

I’ve learned today that the XVTR port on the MB1 is not in use for transverters. So you need to use split IF and DAC in ADC out. I don’t have any split IF transverters so I’m unfortunately out of this loop until they enable the XVTR port :wall:

Roman said in an email that the XVTR a port will be working before the release of ESDR3 1.0

So that’s good news!

Is there a reason why we cannot select A2 or A3 in transverter settings? My 432 mhz and 900 mhz transverters need 4 watts drive and have a single IF input.

Thanks
Tom

Hello Tom.
Because using only one VHF antenna, which works in the second Nyquist zone in range from 80 up to 160 MHz with 8W in SS2PRO/DX, is safer and more convenient.

Hi Roman
I do not understand you answer , all of my transverters have a single IF for input and output at 28 MHZ , so what does 80 to 160 MHZ have to do with 28 MHZ on A2 or A3. If I tune to
10 meters I have the option of A2 A3 and ADC/DAC. So I guess the only way to use my transverters are the 10 meter band and not the transverter manager.
Thanks
Tom

The same here. Using 28MHz IF for all bands from 2m to 10GHz...all are DB6NT with 4W drive. An the second issue is that I am using SunSdr2QRP as a VHF-UHF-uW IF. But there are NO ADC/DAC conectors in QRP version of SunSdr2, so I use common output. Only displayed frequency is 28MHz IF. There is no problem durind last few years. This can be solved very easy...including BAND DATA on EXT connector.
