My ULR test

Powell
 

My ULR test to see what the RF-032D Panasonic "Mr.Thin"  is really like.  I expected it to do pretty well.  But it handily beat out these:

Sangean DT-400W
Kaito WRX-911
Tecsun R9012 (Gary modified)
Sony SRF-59 (Gary Modified)
Eton / Grundig G8
CC SWP
It was about equal or slightly better than my Eton E-10 which I do not consider that much of an ultralite.

Re: IBOC and ssb or sync detection

I was told the sync on the 2010 will automatically pick which sideband to switch to in a strong selective fade.  That's when I am in regular wide AM and press the sync button.  Until WTAM and KMOX started running IBOC that was  "**THE"** only way WBT was listenable at night and I'm 80 or so air miles from the transmitter. Now, at night 1110 is just   FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
I am lucky to be close enough  to hear the WBT-FM on 99.3 from Chester, SC .

Three more for the Log and it's my 1st year ULR anniversary.

Alex
 

Well I got to DX some more sunset after two days of not being able to, because of school.

 I got three more and a tease. One should be as obvious as the nose on our faces.  I've never reported for I foolishly had blinders on, while I was in a states heard race. If I heard stations that were from states I already logged, I ignored them. And I never put them in my general log for the stations heard total, especially if it was a 50 Kw guerrilla. Now as I study my logs nightly along with a "dupe" system in place, I now have a better picture of my strengths and weaknesses and "frequency holes" (frequencies that I've never logged anything), yet another weapon in the ULR AM-DX, arsenal.

  It's neat to see how much I've learned, organized and grown in the AM-DX hobby in just a years time. And I looked at the log and the calender, Realized it was my first year of DXing ULR style. So I'm now a little older and a little wiser!!

   Enough about me here are this evenings logs.

  All were logged with a barefoot SRF-59, all time are in UTC. AMP stands for Air Mile Path from the stations area of service to my QTH in Springboro, OH.

And then theirs the tease.

Unfortunately the station disappeared in to the mud as it got dark without any other clues in the aid of identification. Such is life. It would've been nice to log a elusive New England state and the smallest state in the union to boot!!!

Piles of Ultralites

Powell
 

I had been looking for one I could listen to on my daily dog walk I call "The Morning Mile".   ALL of the current UltraLights had something negative that made them a bit inconvenient.  A friend of mine reminded me of the Panasonic "Mr.Thin" series from around 1980, and he has 3 of them. He recently got a RF-032D to replace the one he has that is worn out. He said it was very hot, and I remembered mine, which got stolen.  I got a one yesterday on Ebay, and it's in great shape, and yes it is smokin' hot. It is thin enough to be in my shirt pocket and not be a pain. It plays loudly and I can do the dog walk without having to continually do something to the radio..... like HOLD it.  I will be testing it against some of the new whiz bang ones I have now.

That's the way mine works, and if you have the sync on and there is a selective fade with IBOC .... WHOOO boy you get the digital rushing noise that reminds you of a train running through. It's better in narrow, but PFFFT I would rather listen in wide.

The 2010 shouldn't "automatically" be selecting the sideband in sync mode. Mine doesn't work this way.

Also, listen to the 2010 in sync mode on an IBOC station, and you'll hear digital "rushing" noise, no matter which sideband is selected. On the E1/E1XM, in DSB sync, this noise is absent.

That's strange as there IS sync on mine in  the AM DSB mode. The Sony 7600 has sync also but it's not as good. Sync detection should be standard on ALL radios made that have an AM section!

The Icom R-9500, at only US$16,o00.00. This receiver can be produced because there is a large market beyond hobbyists. At 20 kg, it sure isn't an ultralight! This top-performing receiver has features that can't be implemented in DSP alone, such as roofing filters and LC bandpass filters. SSB alone doesn't make a DX radio, and real DX-ability won't fit in a ULR-sized box. Some things can still be done better with lumped analog components.

ULRs are fun, but there are good reasons why some DXers use ICF-2010s etc as spotting radios. For less than US$100 and their small size, you get a lot of performance, but I think we're approaching the upper limit.

basic facts on DX-receivers

Wolfgang Hartmann
 

Hello

Ultralight Radios


There is a big step in the technique of radios generally by:

Software Defined Radio
DSP receivers

We have the advantage that by newer technique there is a lot of progress working

- Sharp shape factors in overall filtering at hf and audio

- Freqency-stability by comparison to a xtal-frequency within
software (in a programm or chip as DSP-chips)

- Working in digital mode with a lot of advantages



The new chips, SI4734, SI4735, work in DSP-mode. They are in use at Kchibo or Tecsun in China for the purpose to generate a very cheap production price. They too work in Navigation Advices. There are similiar ics too.

The main purpose till now, is the reducing of production costs. To have very little effective radios for the chinese market.

Till now, they are working perfectly under FM.

SW-working needs generally a wire some few meters long connected to the antenna.

MW und LW working with a ferrit-rod antenna connected to a long wire antenna.



There is not at the moment a DSP-receiver for DX-interested people.
Some features should be built in as SSB, LSB, USB maybee others too as specialities as DRM, DRM+, DAB.

Kchibo announced a receiver KK-S7600L with SSB-features. And we should wait for more receivers for DX-specialists.

The DX-community all over the world has a special interest in receiving even weak stations all over the world. The new factor on the market for our interests are the normal DSP-receivers, which we are able to use to a certain content.

The DX-specialist receivers are not at the market till now. We should wait for them and demand them. The classical DX-receiver producers will die because of their historical technique.

I love old tube receivers from the time before World War II. One has to ask, why those old renovated receivers are so fascinating even more than „modern" DX-receivers. The future will show, that we give a lot of classical receivers to radio-museums or collectors (a fascinating hobby)!

Re: IBOC and ssb or sync detection

lrdheat
 

I tried an E1...it's sensitivity off of the whip was similar to the G5. I was hoping for a miracle off of the whip (which I'm sure isn't possible to engineer, but hope springs eternal...) Of course, the superior sync modes and 10 Hz ssb increments allowed for superb ECSS listening. Both sidebands sounded identical on the E1. As is the case with my G3, the SONY 7600 GR sounded more natural on the upper sideband, muddier on the lower, although again, not unpleasantly so. On mw, the whip proved ok sensitivitywise, but un-nullabe. In am mode on sw, the G5 is beadier, less steady, weaker on the weaker signals than the G5. On ssb (or sync), the G3 is much closer in (perceived) sensitivity with the G5.
 
On your G3's...do you have local station mixing products when utilizing ssb or sync? I find that I can defeat this by touching the bottom of the antenna as I hold the radio, or by using the attenuation switch. The G5 and SONY 7600 GR did not suffer from this.

Hi Powell,

Actually the Sony 2010 has SSB sync (USB or LSB), but not DSB sync. I've owned one for about 24 years.

I owned several E1XM units, but never got one that worked totally right.

The best sync detector of my current radios is on my Sat 800, but it doesn't have DSB sync.

Both the E1/E1XM and Sat 800 have better sync detectors than the Sony 2010, but I doubt that these two models will still be working after more than 20 years.

I had a question concerning IBOC and sync: A strong signal (at least at my QTH in Laredo, TX) from an IBOC station (KRLD Dallas 1080 KHz) creates quite a bit of hash on 1070 and 1090. When using my Grundig G3 on 1070 (KNX Los Angeles), I was expecting to have less hash on the lower sideband or lower sideband sync than on the upper sideband (or upper sideband sync. Surprisingly (to me), the signal from 1070 was cleaner on upper sideband! When I checked for reception of a station on 1090, the LOWER sideband was cleaner! Why would this be?

> The G3, by contrast, is sensitive below around 1100 KHz, and much less by the time frequencies above 1400 KHz are tuned in. The situation improves when tuning sync or ECSS style, but still remains less sensitive than the G5.

How does the G3 compare with the G5 on LW? It sure sounds as though the antenna isn't tuning well at the high end of the band. If there were too many turns on the antenna winding, LW and low-MW reception would be good, and perhaps better on the G3 than on the G5. I'd be tempted to do an internal antenna mod in that case. What the heck it's not a legal ULR anyway, might as well. :)

If the BFO is adjustable, then there is no need to align it. I can't explain why one sideband sounds different than the other, but whatever is causing that, combined with the IBOC protocol, would explain the effects you're hearing.

I had an ICF-2010 many moons ago, and never found sync detection that useful on the BCB, with so many signals. Once you get two or more carriers on one frequency, the sync detector doesn't know what to do. ECSS sometimes helps on weak signals, but what I'd really like to see on the next-gen of SiLabs chips is a heterodyne detector that would recognize a continuous tone (I guess it would have to work at audio freqs) and notch it in software. Trans-oceanic listeners would love that!
