Don't be put off by the location of the company. They've garnered quite a nice reputation as being friendly to the hobby. Just remember to keep your receipts and shipping box in case you have to return it for some reason

OK I am going to just add to BS's post - I hope this is OK!

I just compared my Sony 2010 - Sangean ATS909X2 and the new S2200X.

No tech stuff here; just my quick thoughts.

I compared the following frequencies - and was just using the Whip Antenna's (That is why I have portables - I have desktops with attic and outdoor antennas)

6070 Good Signal Tecsun Best Audio Sound
5050 Good Signal Tescun Best Audio Sound
7325 Good Signal Sony and Tecsun Tied
9330 Very Weak Signal ATS909X2 Best

So all in all I am very happy with this S2200X!

Interesting but one day does not a decent test make. Now do some tests over a couple of weeks, different propagation conditions...now we're talking a test

I totally agree, that is why I said it was my first impression. I am continuing to evaluate my new receiver. So far I have not had any occasion to update my original thoughts with any new revelations. I have been using it on multiple frequencies in various segments of the HF spectrum. I have also occasionally ventured into the LW and air bands. I can’t say I have much to judge from on those bands from my location. However I can say that my experience on these bands are no different than on my 501

BlackSwan,

When you can, I wonder if you would try the following for me: tune up on the ham bands to an SSB signal and try to use the RF gain to remove some of the noise floor. I've done this with my ham rig (none of my SW radios have an RF gain) and it seems to make the signal more intelligible and more pleasant to listen to . . . because of less noise "underneath."

Could you give that a try (or two) and report here what your experience was?

On my S2200X, the RF gain does literally nothing, unless I have Attenuation set to max and then it is about useless due to no signal. This seems to be a major flaw - why have a RF Gain if it does not work?

It probably measures the incoming signal strength in DBM and then only activates if it's under a specific value. My guess is it's only useful with the telescopic whip antenna and weaker stations. The catch is the noise floor could be high and that may be affecting your 'value' negatively.

I tried it tonight on some HAM frequencies.. The RF Gain does work when on a signal. Although it does not help static as you turn it down. It does drop the signal odly enough it does not change the S Meter but you can listen to LSB or USB and turn it down so far you can it hear it anymore

I need tone do a quick check on a SWBC signal now I guess

The noisy DSP chipset and lack of front-end preselection means the noise floor will be unacceptably high and this impacts SSB monitoring significantly. Combined with SSB distortion and poor AGC timing you've effectively got nothing but a cheap portable in a big fancy box. Why people waste their money on such deceptively overpriced junk is beyond me. It seems people did not learn from the Tecsun S-2200/Grundig 750 just how bad these receivers are for anything beyond broadcast listening. I blame a lot of this on those clickbait morons on Youtube who push junk receivers and propaganda to increase video traffic. True objectivity means nothing to these greedy BS artists.

A fool and his money ...

. . . but you have tried the technique of "riding the RF gain" on an SSB signal? Did you find it worked for you?

It definitely works with my IC-706MkIIG.

I'm trying to see if there is any portable that offers that capability.

In reply to that: As I mentioned this hears and sounds better, 90% of the time than my Sangean ATS909X2 or my Sony ICF-2010 - (With just a whip - after all - it is a portable - I have a few top notch Ham Rigs and outside antennas for more serious listening) So I do not consider it a waste!
