I did some hard work with the 23cm DV/DD radio units yesterday at Kauniainen Radio Club where I participated the weekly NAC contest by yelling comments to the radio shack from the workshop :)
All three radio modules have now decent antenna connectors (SMA) and the previously loosely wired service (USB) interface and the control interface are now wired to a neat D9 connector. The DD transceiver unit had both TX and RX control lines wired out so I needed to go for a D15 connector. I actually thought using a D15 also for the DV transmitter and receiver units, it would give free pins to wire RSSI, PTT, discriminator output etc. to use the modules for analog FM also. I might do that if I just find information about the required lines!
I was really surprised about the lossy and very low quality coaxial cable which was used in the original setup. The cable was not long but the connection to the chassis N-connector was quite HF-style I must admit. Now there's a SMA connector directly on the chassis which I consired well usable. Below is a close-up photo of the antenna connector revealing the details of such.
