I took delivery of an XHDATA D-808 portable today.
Initial tests yielded relatively poor FM performance when using the default (short) whip antenna. My Tecsun PL-390 easily outshone it; for example, 88.0 MHz Nimmitabel was clearly received on the 390 while the XHDATA got nothing! Upon performing an antenna transplant using the 1 m whip previously attached to the Tecsun, reception markedly improved. The performance was now roughly equal to a Sangean PR-D15 on FM. RDS from Canberra stations Hit 104.7, Mix 106.3, and 2XX was obtained and there was a good period of aircraft scatter from 107.1 and 107.9 Coonabarabran.
I briefly tried AM; performance was good with notably low noise reception, resulting in clean crisp audio despite the small speaker size.
The XHDATA suffers from processor noise on some FM frequencies which can mask weaker signals. Overall, it’s a handy performer considering its compact size, RDS capability, and rotary tuning (100 kHz steps). I give it 3.5/5.
