Now, I am very happy to be told I am wrong, but I think DSB rigs can be received on other DSB receivers, but it is much more tricky than receiving DSB on an SSB receiver. I have no experience of this, but a comment on a post yesterday has me thinking. The comment was made by Ken G4APB. Thanks Ken.
Clearly a simple SSB 10m transceiver (if very low cost, simple and easily copied) would be much preferable to a DSB transceiver, but I am unsure of the relative costs.
If you have experience, please let me know.
Clearly, if 2 DSB transceivers can not (easily) communicate, maybe a simple 10m DSB transceiver is not as ideal as a club project, even though most QSOs would be with SSB stations.
I wonder how inexpensive a 10m SSB transceiver can be made as a simple kit?

Hi Roger, I just thought, if your DSB transceiver design was taken up as a club buildathon, as people tried to communicate with each other on these rigs, what actually is the difficulty receiving that you mention?

Hi Ken, My simple answer is I do not know! On reflection some years on, I think an SSB phasing transmitter might be better coupled with a direct conversion receiver. Someone cleverer than me might be able to make a low cost phasing direct conversion receiver to help reduce pickup on the LSB frequency. As you can see, I have never coupled a DSB transmitter with a DSB receiver. I thinks the problem comes with netting very accurately, but I do not know.
