![]() ![]() This tuner may have worked well with a balanced feed line (didn't try), but manual says it works with end fed wire and it didn't (even after try a variety of lengths). Returned it to dealer (and ordered a Palstar 1500BT instead). They agreed that it was 'defective' and gave me the option of returning to the dealer or to MFJ for a new one. The "antenna" tuning capacitor knob had little or no effect on the meter. Could not even get a near match on all bands 10-160m. Attached to the same lug, a grounding wire to the the house service grounding rod directly outside the shack window (tried both with and without this ground- ing condutor). Had plans for a 160m horizontal loop, but first hooked it up to a 120'(also a 144')end fed wire antenna with a 1/4 wave counterpoise on each band (two on 160m), the counterpoises were installed 14" above dirt and attached to the grounding lug. The metering is accurate and easy to read, the build quality is of a reasonable standard. (Yes it tunes my doublets on 6 metres and I have had some great contacts). I now have two of these tuners, the B model (80 -6) and the HB model (160 – 6). ![]() The same holds true when measured using various doublet antennas and overall I am impressed with this tuner’s performance. In making A/B measurements, using a pair of calibrated RF ammeters and various balanced loads, the MFJ unit comes very close to the the link coupled unit and, on some bands, is a little more efficient. The best, in terms of RF efficiency and balance, was always the link coupled unit but that is no longer the case. Z-match,T-match + 4:1 balun and a classic link coupled unit. Over the years I have acquired many different tuners i.e. But as long as you’re using its optical output instead of its 3.5 mm analog output, the sound quality is pretty solid.I have always been a big fan of simple efficient antennas fed via open wire or ladderline. Unfortunately, it has some operational quirks that appear to be common for models in its price class and make it less intuitive than the iFi Audio picks. It also has transport controls that allow you to skip tracks without unlocking your phone or other portable media player. ![]() In addition, you can either leave it connected to power or use it as a portable device, as it has pretty decent battery life. ![]() The 38071 can function as a Bluetooth receiver or transmitter, though we tested only its reception capabilities for the purposes of this guide. It supports the most common Bluetooth audio codecs but lacks support for a couple of the more esoteric ones that audiophiles may appreciate. If your main priorities when shopping for a Bluetooth receiver are price and portability, as opposed to ergonomics and pristine sound quality, the Monoprice 38071 Premium Bluetooth 5 Transmitter and Receiver wins out over other comparably priced offerings. All the rest of our test units either became unstable or lost connection somewhere within the 1,518-square-foot suburban home in which we did our testing, but the Zen Blue V2, fitted with the supplied long-range antenna, maintained a stable connection from an iPhone located all the way in the far corner of the backyard.Ĭombine that with easy setup, reliable and near-instantaneous reconnections, and an attractive form, and the Zen Blue V2 is the best pick for demanding audiophiles, despite its lofty price tag. The Zen Blue V2 is also a great choice if you need more signal range than most Bluetooth receivers can provide. Connection-wise, it has you covered with both optical and coaxial digital audio outputs, as well as a 4.4 mm balanced audio connection and stereo analog RCA outputs. If you have a high-end audio system or would prefer a Bluetooth audio receiver with digital audio outputs, the iFi Audio Zen Blue V2 was without question the best-sounding Bluetooth receiver we evaluated in our latest round of tests. ![]()
