Hi Frank,
Does the TECSUN have an antenna jack so it could be used with a
directional antenna on the aircraft band? Does it have an S-meter?
Google is your friend.

http://www.radiomanual.info/schemi/RX/TECSUN_PL-660_user.pdf There is
an "antenna jack" on the side of the radio, but no indication whether
it's coax or a single wire.
I haven't seen one of these radios, but I took a borrowed TECSUN PL-380
to Dayton for use in the hotel room. $45 at amazon.com It has a DSP
IF, which makes it spectacularly good at receiving weak signals next to
bigger ones. I have a vintage Technics ST-9030 (mid-70s, 8-gain tuned
front end) and a Carver TX-11a hooked up to an 8-element pre-amped,
roof-mounted Yagi pointed to San Francisco. Both hear signals on 91.5
MHz and 91.9 MHz full quieting, but only noise on 91.7 MHz, and the NPR
station on 88.5 MHz is there but not nearly full quieting. With a clip
lead from the center of the coax to the rabbit ear of the Tecsun 380, I
hear a station from Paso Robles on 91.7 MHz off the back of the antenna
full quieting, with only occasional mild bursts of buckshot from the
other two stations, and the SF station on 88.5 is full quieting. A $40
HDR "Insignia" brand HDR table radio from Best Buy has a DSP IF and
works as well. The PL380 has shortwave to 22 MHz. I haven't played with
it. It does not cover the aircraft band.
These radios are made in China, but I suspect they may use one of the
chips made by Silicon Labs.

HD radio appears to have gone the way of the 8-track tape -- except for
one or two legacy mega-buck high futility products, that Insignia is the
only non-automotive radio currently being sold. Several years ago I
bought a nice little Sony HD radio at Fry's for about $100. It was
discontinued soon after, got glowing reviews, and sells for $500 used if
you can find it. See K6STI's review.

Yeah, this is off topic, but these low cost consumer radios have blown
me away.
