TECSUNの新製品PL-680です、昨年末あたりからネット上で噂が飛び、ホントに製品として発売されるのか謎でしたが、いきなり出荷が始まったようです。
スペックを見ますと、どうやら「PL-600のリニューアル版」というような位置付けですね、ミドルクラスのマシンで、PL-600と比較すると、エアバンドが追加されただけのような気がします。
PL-660に有ったような同期検波も付いてません。
うむぅ・・・このスペックだと、あまり面白味が無いですね。。。
お馴染みAnon-Co.から買えるみたい(送料込で15000円弱?)ですが、
あちらは明日から2週間は旧正月で、営業はお休みとの事、買う買わないは、少し考えてから決めたいと思ってます。

ミニーさん、こんばんは。
PL-680が出ましたね~。
Anon-Co.の商品説明を読むと、同期検波機能はありますよ。
商品の写真にもSYNCボタンがあります。
ただ、PL-600にAir Bandが加わっただけならポチる気持ちにはなりませんね~。

こんばんわ
あららSynchronous Detectorって書いてますね、
見落としてました、お恥ずかしい(*^▽^*)ゞ
PL-680は目新しい機能が無いので、ポチるかどうか迷いますね、
SWLing Post のレポを見てから、決めようかなぁと思ってます。
HI THERE…I CAN ONLY SAY THIS I DO LIKE THE LOOKS AND PERFORMANCE OF THE TECSUN PL 600 AND ITS BUILD QUALITY WITHOUT DOUBTS ITS A GOOD RADIO NOW THE PL 680 IT APPEARS TO ME THAT IT TAKES THE LEAD WITH ITS NEW EXTRA SETTINGS S/N, AIR E T C . BUT ONLY WONDERING IF THE VOLUME AND SOUND CONTROLS HAVE THE FEEL AND GLORY CAPACITY OF THE PL 880 AND IF THAT ITS TRUE THEN THE PL 680 CAN BEAT UP ALL OTHER PORTABLES .-
Hi george.
Thank you for your information.
I’m interested in New PL-680 radio.
According to the review article of “The SWLing Post”, the AGC function has been improved.
Past of TECSUN’s radio had problem of “Soft mute” (it is also known as “Dynamic squelch”).
Fortunately, this problem seems has been removed in PL-680.
I’m going to determine whether to buy it after I examined other review article.

HI THERE…THERE IS NO DOUBT THAT TECSUN HAS MADE PROGRESS AND DID A LOT FOR THE RADIO LOVERS AROUND THE GLOBE AND NOW ESPECIALLY WITH THIS PORTABLE 680 BUT I MYSELF FOR NOW REMAIN CAUTIOUS OVER IT AND TAKE TIME FOR THE FIRST PRODUCTION TO RUN AND HEAR FIRST HAND REVIEWS AND PUBLIC OPINION OVER ITS PERFORMANCE SO UNTIL THEN LETS WAIT AND SEE WHAT HAPPENS .-
Hi george.
You are also considering the same way as me.
I want to know that information that enumerate below.
(1) whether the performance of the band-pass filter? (Wide / narrow switching)
(2) whether the performance of synchronous detection? (The follow-up performance to signal fading)
(3) whether there is any internal spurious problem in MW band? (This problem was there in PL660)
(4) whether sensitivity and intermodulation characteristics of the FM band?
Let’s watch for a while !
lol

I AGREED WITH YOU…FOR THE TIME BEEN LETS JUST DO THAT BUT SINCE I’M AM / MW DXER I WILL LIKE TO KNOW IF WEAK RADIO STATIONS ARE STABLE AND WITH S/D ARE KILLER BOOST SUPER STABLE AND WITHOUT THE NOISE PUMPING MACHINE I REALLY LIKE TO SEE A TRUE PORTABLE THAT CAN DO ALL OF THESE THINGS THEN I KNOW I HAVE THE PERFECT RADIO NEXT TO MY BED.-
Hi george.
I also want to get “THE PERFECT RADIO”, Haha…
In Japan, the Radio Law is changed, it will begin dual-broadcast of the FM band at the famous MW stations.
In urban areas of Japan, the reception of MW station is becoming difficult because the building of rebar to shut off the radio waves .
In such reason, I will be especially concerned about the performance of the FM band of PL680.
Your perfect radio, also would be perfect for me. :)
mini
HE,HE.HE…I SEE YOU ARE A CRITICAL LISTENER THAT’S GOOD BUT ONE THING ITS TRUE THAT IF THE TESCUN PL 680 IS NOISELESS ,SMOOTH AND STABLE IN AM/MW AND WITH NICE VOLUME AND TONE CONTROLS AND OF COURSE SYNCHRONOUS /D. THAT IN MY OPINION IS AMAZING RADIO AND A KEEPER,ADIOS.-
Hi george.
Yes, I am Japanese critical listener, hehehe.
I subscribe an article of “The SWLing Post” about PL680’s synchronous detection.
I can distinguish PL680’s sound, whether Audio Sample A and B.
As long as these sample sounds, I believe synchronous detection performance has been improved.
It able to keep synchronous, even if the weak signal of fading.
I think may be PL680 is “PERFECT RADIO” as you say.
mini
HI THERE …WELL JAPAN IS FAR FROM HERE THERE IS NO POINT TO WORRY ABOUT IT NOW ANYWAY IF THIS VERSION OF THE PL 680 ALLOWS ME TO LISTEN AM/MW WEAK STATIONS WITH CLEAN TONES OUT OF DISTORTION LETS SAY A LOTS OF CLARITY AND STABLE THEN ITS SUPER COOL TRUE RADIO AND A CLASSIC AND PERHAPS MY FUTURE FAVORITE SO IT REMAINS TO BE SEEN ,ADIOS.-
Hi george.
I also read an article about medium wave of The SWLing Post.
I think that the AGC attack rate, PL680 as is set in a little SLOW than old radios,.
In general, when AGC is SLOW mode, apparent back noise is reduced.
The S/N ratio has been improved, so I think due to the above reasons.
Although switchable AGC (FAST/SLOW mode) is the best, this request would be cruel for portable radio.
Gracias.

HI MINI…I JUST WANTED TO ASK YOU ONE MORE THING IF THE CONTROLS OF VOLUME AND SOUND OF THE TECSUN PL 680 ARE MADE OF HIGHER QUALITY IN THIS IMPROVE VERSION IN OTHER WORDS ARE MORE SOLID AND DURABLE AND WHEN ONE LAY ON BED DURING THE NIGHT TIME AND JUST DOING HIS DXING JUST NOT SWIFTING TOO EASILY FROM ONE POSITION TO OTHER OR BACK AND FORTH .-
Hi george.
I think maybe you asked about PL-680’s volume control step.
If so, you don’t worry, PL-680’s volume control is traditional analog style.
It is possible to fine adjustment.
The other day, I got the PL-680.
I will write a report article in my Japanese blog.
Please read using the google translate.
Thanks
mini
HI MINI…HOW ARE YOU???WELL NOT ONLY VOLUME BUT FREQUENCY TOO ITS NOT SHIFTING EASILY WHEN TOUCH UP BY MISHAP LETS SAY THUMB AND FOREFINGER PERSONALLY SPEAKING I DO ENJOY THE CONTROLS OF THE PL 880 WHICH IN MY OPINION HAVE A BETTER AND TIGHTER FEEL ON THEM BUT WHAT I DON’T LIKE IS THE AM/MW PUMPING OF WEAK AM STATION SIGNALS HOWEVER IF TECSUN ENGINEERS CAN CORRECT THIS PROBLEM IN THIS MODEL PL 680 THEN IT WOULD BE A HELL OF A PORTABLE AND A KEEPER.-
Hi george.
I describe the feel of the tuning knob.
PL-680’s knob is tight and rough resolution.
PL-880’s knob is loose and fine resolution.
So… I like PL-880
“PUMPING” you say, do you mean that the spurious problem?
If so, it is the unfortunate problem in PL-680.
This spurious problem that has been inherited from the PL-660.
I think, TECSUN should be hearing at the user’s opinion.
mini
HI THERE… PUMPING IS A NOISE OF WEAK AM/MW SIGNAL WHEN RECEIVED BY THE RADIO IS SOMETHING LIKE A MOTOR BOAT SOUND WHICH I HEAR WITH MY PL 880 WHICH IS TIRING ME SOMEHOW AND AVOID IT ,THANKS ,ADIOS.-
BY THE WAY …WHEN SWITCH TO UPPER SIDE BAND OR LOW SIDE BAND IN AM/MW I’M STILL TALKING THEN THIS NOISE PUMPING SOUND IS GO AWAY BUT THEN AGAIN THE QUALITY OF THE SOUND IS CHANGED OF MY PL 880 LIKE THE SOUND COMING OUT FROM A DEEP WELL.
Hi george
I describe my experience, but it might be different from the PUMPING you says.
By the time I got the PL-880, I have noticed that PL-880’s body resonate in a small audio volume.
At that time, loosen the screw of the radio, and again tighten the screws, the problem was solved.
Will be your reference that my experience ?
mini
HI MINI…PLEASE DON’T GIVE ME WRONG FOR ME THE PL 880 ITS A COMPACT SIZE RADIO WITH AMAZING SOUND AND TRANSPARENT TONE AND IN HIS OWN RIGHT HAVE ITS VALUE PERFORMANCE WORTH MORE THAN ITS PRICE HOWEVER DESPITE OF ALL OF THAT MY MAIN PROBLEM REMAIN THE SAME HOW CAN I GET RID THE NOISE HUM…HUM…HUM…LETS SAY OF VERY LOW AND WEAK AM/MW SIGNALS ??? ANYWAY I WILL WAIT AND SEE IF THE NEW PL 680 HAVE SOME ADVANTAGES AND PERHAPS SOMEHOW IS STABILIZE THE WEAKER AM/MW SIGNALS AND THEREFORE MAKING THEM MORE LISTENABLE , THANKS AGAIN ,ADIOS.-
