Even on superficial examination, clearly there are non-trivial differences in the hardware designs.
As this was not an exhaustive retro review of the D-808, I have not gone into the various negatives that every D-808 owner knows to exist. Other than that, it seems to abide <10m/30ft of wire just fine and it gets along with my ML-200 active loop, currently indoors with a rigid 80cm aluminum loop, unless the RRI transmitters populate 49 and/or 41m after midnight. That station occasionally hits the 9+60 mark on my SDR with a dipole and when they’re on, the D-808 has to be tuned far away from these bands or disconnected from the loop to stop the pumping, desensitizing and intermodulation products. Interestingly, strong signals often make the filter drop out (as described under “SSB reception”) as well. A theory could be that this happens when an off-band signal (and/or the AGC causing “clipping”) makes an AD-converter run out of bits. to allow FM and AM station to be saved to the keypad and accessed without having to select either AM or FM beforehand (a function of the 7600D). Last week, I posted a few photos of the new XHDATA D-808 and Digitech AR-1780–two of the hottest portable shortwave radios to hit the market in recent months.
AM bandwidth control on the ATS-909×2 is quite nice. However, what leaps out is the absence of multi-bandwidth capability in SSB mode. It’s baffling that Sangean seems not to have recognized this as a must-have feature. Refer to the close up photo above. Following the precautions described, solder the two Litz wire leads down onto the circuit board at an angle, as shown in the photo. After soldering, make a close visual inspection to ensure that there are no solder bridges across the Litz wire connections, or nearby components. The remaining length of the Litz wire leads should be routed in a horizontal manner to the wrist strap hole. More recently (2023?) the internal circuit of the of the radio was radically changed and users are reporting that the new version isn’t as loud. This version can be identified by rubber feet on the bottom and a USB-C charging connector (the prior version has a USB Micro). Others are speculating about poorer performance. I’ll post an update when I know more. Mine is this latest version. You can read more about the update on the Ultralight User Group. Operation
Direct frequency input needs to be initated with the “Freq” button though, and in some cases (shortwave frequency <10,000kHz) you need to hit it again to enter the frequency. The D-808 has up/down buttons in addition to the main tuning knob, they are stepping through the bands in the “Fast” step width so you can pretty much always leave the tuning knob on “Slow” . Pressing these buttons longer than 3s starts the band scan. Holding each of the left side band buttons starts the “ATS” scan-and-save-to-memory automatic.
I said I would share my results for attempting to receive LW signals on the XHDATA D-808, & if I can use a longwire to improve reception on this radio. This was after posting videos when I used around 50 metres of longwire connected to the D-808 for improved Medium Wave reception & to prove it works. CCrane Skywave (the original - no ssb) - Good for FM & Weather Alerts. Bounces between the car console and the house. The second pair of digits is a crude calculation of receiver (not audio!) SNR, which can be useful in conjunction with the signal strength meter, e.g. for adjusting or comparing antennas and so on, and it works best with AM and FM signals.
Great Deal
