More to my original post on the Redsun RP2100 after further use.
MW mediumwave reception on the BCB band still amazes me with it's clarity
and sensitivity. Regular reception of stations that are 5,000 miles/8,000
kilometers away with good readability is possible on a regular basis. The
local
stations that are 700 miles/1,200 kilometers away simply boom in with great
sound and clarity. Very impressive on a portable with only a ferrite
internal rod. Provision is made on the back for the connection of a longwire
antenna to a 500 Ohm post, also a ground/earth connector, but I have not
tried this as reception on the internal ferrite rod is so good.

FM band. The most powerful FM receiver I have owned is my Drake SW8, but the
RP2100 is quite a bit more sensitive on the internal whip, and the marginal
long distance signals are a lot clearer. It leaves my GE SRIII and Sangean
818 in the shade.

Connecting to AC mains. This works seamlessly and cuts off the battery and a
mains indicator appears on the LCD display. Only snag is that this
introduces a lot of RFI hash onto the MW band and makes the more distant
stations unpleasant to listen to. It doesn't seem to affect the FM or SW
bands at all though.

Connecting a powerful 50 Ohm antenna for shortwave. I have a RF Systems DX-1
Pro active antenna which produces a very strong signal to the receiver. If I
connect this to a portable it overloads it badly and even risks blowing the
front end FET's. I connected this to the 50 Ohm input of the RP2100 and
enjoyed
amazing SW reception with NO signs of overload at all. Compared with my much
more expensive tabletop receiver the RP2100's performance was impressive and
on many stations the RP2100 was preferable to listen to because of its warm
wide spectrum sound compared to the rather tinny and shallow sound of the
tabletop.

The RP2100 is no tabletop though as it does not have the extensive
facilities of my big Icom to clear up various forms of interference. All you
can do is narrow the bandwidth and offset the frequency slightly either side
to rid yourself of the interference, but often this is not sufficient.
Actually, having owned a Kenwood R1000 for awhile, I think the RP2100 would
substantially outclass it!

The 50 presets/memories have driven me Harpic, that is clean round the bend,
so I no longer use this function. You see, if your favourite station is on
preset 1 and you have been tuning around, when you want to go back to your
favourite station and press the preset button, it will go up one, so you end
up on preset 2. You then have to press the preset button another nine times
to get back to preset one. That's annoying and time consuming, so it is
faster to use the excellent "Q tune" function button to get quickly around
the dial to where you want to be. Q tune jumps one segment up the shortwave
band at each press, and the fast tuning knob will take you quickly to where
you want to be.

Altogether by far the best portable I have ever owned, including my Sony
2010. Very satisfying performance and excellent value for money at just over
$100.

Just when I thought I had bought the ultimate, on the way is a mouthwatering
Redsun RP3000. This upcoming receiver looks the same as the RP2100 but with
a few button changes on the face, but is said to offer:
# Air band for aircraft
# numeric keypad
# 1000 presets
# sideband selectable synchronous detection

Has anybody else seen this?

It's supposed to be out by the end of the year. It supposedly has a
sync detector.

Sorry, John. I missed the last part of your message. I guess you've
seen it.

It's been a long day.
