That definitely sounds to me like a moderately significant improvement in
signal, Gary, considering it was apparently blank without the nano-FSL or
whatever you want to call it. :) (Although on my S-rating system based on my
perceptions of RST, I'd probably rate that signal as an "S4" - my "S9" is
usually signals that show 88+ dBµ on the Tecsuns without any external antenna
boost, and anything over S9 is 95+ dBµ.)
I wonder if there's a chance we may someday have a small and inexpensive enough
FSL so that you could have it and the Sangean DT-400W or CC Pocket both
contained in a $100 budget and a package the size of the Skywave or PL-380?
(I'm thinking the radio would be mounted inside the FSL but with the
buttons/display somehow still accessible, and instead of being round it'd be
more rectangular (or oval), but would that not work?)
Also what about an FSL that, instead of being fairly wide relative to its
diameter, is shaped more like the Select-A-Tenna (or oval) but smaller?
Also I was reading other comments on Yahoo and wondering ...
What's the difference in the various versions of the CC Skywave?
What would happen if you used a 330/46 connection to the radio, but made the
main coil of the FSL with 1162/46? (I'm guessing the tedious part would be
individually soldering each strand of one type to the other, or would a single
bulk-solder work?)
How does the direct-connected FSL compare with the built-in antenna on adjacent
and off-channel RSSI, blocking, assuming you're using signals of comparable
strength? (Meaning a signal that indicates 89 dBµ on the FSL, and another that
indicates 89 dBµ on the stock loopstick.) Does the FSL have higher Q, and not
block stations as much as the stock stick?
Also, Skywave vs Traveler 3 - which do you think I may potentially be happier
with on AM and FM for the price? Fry's has the Skywave here but they want $70
for it and I think that's too much for that model. I had one briefly but the
display is terrible outdoors in bright light, also I had some other issues with
it too. (Some of my complaints with the PL-380 were improved, though.)

Hello All,
The new-design 3.7" FSL is one of several experimental models being tested in
an effort to design low cost, high performing models for the MW-DXing
community. The 3.7 inch FSL is of a very tiny size (a photo is posted at
https://app.box.com/s/e8pv0rh2ydoeyu6rjqewjc8yq3dsd2kr ), but it uses the
highest sensitivity Litz wire available on the commercial market (1162/46).
This is the same high-sensitivity Litz wire used in the monster FSL models on
Oregon cliff DXpeditions. The 3.7" Baby FSL is designed to be constructed for
under $100 in parts, but it packs a very powerful performance punch in its tiny
size.
After completion of the first test model this morning the antenna was tested
out in the reception of 1566-HLAZ at 1507, and received this Japanese service
signal at an S9+ level on the CC Skywave (as shown in the photo linked above).
Without the FSL antenna boost the Ultralight radio had no reception of HLAZ at
all.
