Re: Tecsun PL-360 Plug-in Loopsticks-- Huge AM Sensitivity Boosts

It sounds great,Gary ! I will await the results of your experimentation eagerly.It would be great if they made a bandwith selectable DSP ulr that had a plug in loop stick.Something like a PL-380 with a plug in for a loop stick.

Hello All,

The Tecsun PL-360 is one of the smallest Si4734 DSP-chip Ultralights, with
a rather modest stock loopstick. It has fixed 3 kHz DSP selectivity, and
fully enabled soft mute-- similar to the Tecsun PL-300WT/ Grundig G8 models.
But is does one have one stellar quality that is unique among the DSP
Ultralights produced so far-- the loopstick is of a plug-in variety, using a
standard RCA phono plug. The owner can switch to an extremely sensitive 7.5"
Amidon loopstick within a couple of seconds, without doing any "surgery" to
the radio at all.

Today the first Amidon 7.5" plug-in loopstick for the PL-360 was created
here, and it transforms this modest radio into a extremely sensitive DX
chaser, fully equal to the E100 Sliders, 7.5" loopstick PL-380's and other
DXing sensations. Both sensitivity and nulling ability are the equal of any
other modified Ultralight, and the fact that a user can obtain this massive AM
sensitivity boost without any modification to the radio is very exciting.
For domestic DXers who don't usually need 1 kHz DSP selectivity, this radio
may become a dream machine.

The stock 300 uh loopstick coil can easily be replaced with a plug-in
design of the user's choice, and besides the 450 uh type 61 7.5" loopstick model
shown, a medium-sized loopstick (on a different length of type 61 bar)
will shortly be tested out here. The plug-in loopsticks may well make this
model one of the most popular Ultralights for domestic DXers, and an ideal
platform for loopstick experimentation.
