Have the Alinco DX-SR8T transceiver here. Got the transceiver as it only cost a bit more than the DX-R8 receiver, but rarely use it for TX, got it mostly for SWL... mostly LW NDBs and MW AM BCB DXing. The receiver in the transceiver specs and operating instructions appear to be very similar to those of the stand alone receiver, however, the transceiver RX lacks the SDR output if that matters to you.
This was my first Alinco radio so didn't know what to expect but have had the radio for a couple of years now and have been quite pleased with it. Yes, the buttons are a bit small but not really a problem for me. The radio measures about 10" W X 4" H x 11" D... maybe a bit "small' but the display is large and bright. Audio out of the small front facing speaker is surprisingly good but most of my listening is done with headphones. By today's standard, a very simple radio to use. Very simple menu, easy to understand instructions, about as intuitive as it gets nowadays. The receiver is very good on LW, very sensitive, good selectivity and filtering too... can easily pull a Canadian 400 cycle NDB out from between the sidebands of a 1020 cycle modulated U.S. NDB on the same frequency.
Have not used it that much for HF SWLing but it does a good job receiving the aviation VOLMET stations.
Overall, very happy with the Alinco radio.
