Welcome to "Dave's Radio Receiver Page". Here is my little spot on this earth to pass along my experiences and or comments about "Radio Receivers", as well as other gizmos that I use in my radio monitoring / recording ventures. My main focus is in the "Shortwave" part of the radio spectrum. A few other radio related items have been thrown in too , including amateur radio equipment reviews and views that may not be directly related.

I have been playing around with radio receivers for well over 30 years now, and in this time span my fingers have run across many models, some really good and some really bad. Most comments you read here have been pulled from my own head, but from others as well (as noted). All observations from me are being made with the 2 ear / 2 eye method, so no fancy test equipment here. These of course are my views and your findings may well be different.

Any set being listed on these pages does not mean that I own it or plan on owning.

I'm sorry if any part of this site seems to have a "Soap Box" slant to it , but I "tell it like it is" .

  • The AOR UK web site is NOW saying for the new AR7070 : "......A replacement (more expensive) model is under development, release is expected spring 2010... Several pre-production units have been built and working, but the internal operational firmware needs to be finalised before we move to production". Will the AR7030 be the last of John Thorpe designs ?? We have yet to see one real picture of the AR7070 as of yet. My AOR AR7070 receiver page is still posted with the edited "scribble" drawing that has been passed around the internet for quite awhile now. (Nov 07)

  • As I discovered on the Herculodge web page : " New Degen DE1106 Purported to be a Corrected Grundig G3" . Also see the [Chinese] Degen "forum" web page here. I have no additional information at this time. Is this old news that has just been recycled ? (Oct 31)

  • "AOR AR5000 R.I.P." : Universal Radio (and I bet all other USA dealers too ?) have run out of new samples of the AOR AR5000 receiver (all versions). It was of course discontinued a few years ago and new samples were very limited even then. A replacement ( DSP ? ) model is in the works. Of course any "wide band" (coverage) set will always capture a larger market, but usually with lower performance in the SW/HF part of the spectrum. (Oct 29)

  • Uniden Bearcat BC898T table top "scanner" receiver has been discontinued. If you ever wanted a brand new BC898T, you may wish to purchase one very soon while some dealers still have new samples. Overall a very nice tabletop scanner, but it lacks alpha tags , uses panel lamps for the LCD backlighting (which burn out fairly quickly) and the some of the buttons are very hard to push. See my review on this website for more information. UPDATE : Universal Radio has "sold out" , AES still has new samples in stock at time of writing (have not checked other USA dealers). (Updated : Oct 27)

  • DE1125 "Another Degen Stinker " I had a chance to play with one of the new Degen DE1125 pocket portables and to me this new version offers very little SW improvement over the older DE1123 model. In fact with the tested sample it was actually worse in some area's. Yes, the same very poor DSP receiver performance continues. On SW, it stilll cuts in and out even on strong signals, AGC pumps up and down, hissy, sputters, nasty distortion and narrow audio when it does receive a strong enough signal. FM performs better and perhaps a bit more sensitive, but for some reason it takes a much stronger signal for the stereo to kick in (with headphones in use of course) when compared to the DE1123.

    The worse part of the DE1125 was when headphones were used on SW , (yes I tried different phones and earbuds), the audio went into nasty "oscillation-motorboating" to make it totally unusable . The speaker output never was a problem with this issue.
    Have a listen here. A wav. audio file as recorded off the receiver, SW on 10 Mhz WWV. first without headphones then with. FM and MP3 "headphone audio" is a bit more muffled when compared to the DE1123. Also the headphone jack is on the BOTTOM of the unit. The DE1125's speaker output also has excessive bass response that adds much more break-up audio distortion on the SW and MW bands.

    The tilt stand is a nice touch and latches properly to the set (but is very thin tab of plastic). Still the radio and mp3 player lack any tone or EQ controls. A nice tuning knob improves tuning. However it's very touchy, skips a channel or too while rotating, has a muting-chuffing trait on all bands and slight rotational play. But it's not wobbly (at least when new). Unlike the DE1123 the cabinet is painted to give that "rubber" feeling that so many Chinese radio have these days. The MP3 player capacity is now at 2 GB which is double over the 1123, but alas we still are lacking a shuffle function. The user can now select a mp3 file using the tuning knob which is a huge plus.

    A bit of good news is the DE1125 can record "off air" without having to turn up the volume full blast as with the DE1123. As long as it's electronic volume control is set at 1 or above, the record level stays the same. However, with the tested sample when we plugged in earbuds or headphones on MW or SW, the nasty oscillation went on the recording too !! Another downer is that the recorded file is using the same lousy "32 kbps 8 kHz" WAV format (just like with the DE1123 / KA1123) ? Also it's still lacking is any automation for timer RADIO RECORDING. Now being sold on e-bay for around $ 80 ~ 85. USD shipped (direct from China via postal mail).

    I love the idea of having a good performing pocket radio with a "off air" built in flash recorder. But if your want decent SW reception, I have to say you are better off to stay well away from the Degen DE1125 (and perhaps it's variants that may happen down the road) ?? I will admit that this could have just been a sour sample I used, but maybe not for all bugs as listed above (including lesser audio quality) ? In my view for Degen it just keeps getting worse as time goes on including quality control (if there is any at all) !! The thrill of the old DE1101 is long gone. As many already know, Degen made the G3 for eton-Grundig. Sorry for sour report here, but that's the way it is to me !!

    Kaito in the USA is already selling a variant of this Degen model
    known as the KA800 for $ 80. USD (plus shipping). There is no SW coverage. The SW button on the DE1125 is the US WX (weather) band with the KA800. Perhaps there are a few other differences too (orange LED backlight instead of Green for one) ? With the SW performing and sounding so poorly on the DE1125, this KA800 version (not tested) may not be a bad thing ? (Updated : Oct 10)

  • Grundig G3's "Sync Detection" a dud. The "Grundig-eton-Degen" track record has not been too "great of late" . A number of owners around the internet are saying the "sync detection" is not good on the new Degen made Grundig G3. Appears it only holds lock on the STRONGEST of signals , if it's anything weak....forget it ? Another gremlin that owners have been grumbling about is the poor SSB performance (as compared to the older G5/E5 model). Grundig G3 / eton E5 review and comparison here. (Updated : Oct 02)

  • UPDATE : Icom America has requested that I do not talk about this IC-R75 topic at all for now, so treat the following news below as a observation only that I discovered on the PUBLIC FCC OET web site. Perhaps there are additional "internal" changes that have been done with the IC-R75 as well ?? More on this saga at a later date, that is IF I unearth additional "public" (or "hands on" testing) information. We may never learn the REAL story on this one I'm afraid ?? Who knows ??

    "Switching" AC Adapter to be included with future production of the Icom IC-R75 receiver (for USA samples) ?? I see Icom obtained another update to the FCC OET (type acceptance) on July 28, 2009 for the IC-R75 receiver.
    Click here to view the public FCC OET page. As I compare the 2009 updated owners manual (as seen on this FCC link) to the older manuals, on the "supplied accessories" page it shows a different AC Adapter and added switching regulator information on the bottom of that page. If you look close in the FCC test set up photo's (CLICK HERE) , you can see this new switching AC adapter in use !

    Not sure if this means that Icom is finally addressing the excessive high voltage issue with the OLD AD-55 "unregulated" linear ac adapters with this new regulated switching type for all new samples,
    (I discovered this over-voltage issue years ago, click here for details) OR is it just that Icom's supplier just ran out of parts for the old AD-55's and have now switched to a lower cost switching supply (sic) ?? They may fix one problem and perhaps create another one at the same time (good old switching power supply noise).  But this is "very good" news as Icom must be planning to continue production of the IC-R75 for the foreseeable future.

    With at least the
    "High Fidelity Audio Filter Upgrade" done by Kiwa Electronics, it can sound 1/2 way decent too with the right external speaker. But it's no AOR AR7030 either even after both of the audio mods, but AM mode audio is much improved (in wider bandwidths). (Updated : Aug 08) 

  • I see Universal Radio has the G4000 (A) (YB400) listed again as a active product. As I type this, Universal Radio is including some extra goodies with it for just under $ 100. USD. "The Grundig G4000A is back by popular demand!". They must have found some old "new" samples in a deep Chinese cave ?? But the way eton/Grundig brings back old models from the dead, it could be around for awhile (or not.....who knows) ??

    The new Grundig
    G8 , M400 , and eton FR600 models are all out now. (Updated : Jul 21)

  • Updated the WJ-8711 - HF1000 DSP HF Receiver page. Changed the "software/firmware" EPROM information near the top of the page. Also added the "LED Backlight" failure issue on the AOR AR7030 Receiver page (on the bottom of this page). (Updated : Jul 09)

  • Nick Carrigan checks in with information of a German made DSP receiver marked as the RDR54 from Burkhard - Reuter Elektronik . 1 kHz - 30 MHz plus 50 - 54 MHz coverage. Sorry, I have no additional info on this (see the link for more information and pictures, in German only). Google translation here (main page) (Updated : Jun 19)
