Best receiver for tropical bands?
 
I have been thinking about buying a tabletop receiver for shortwave.
I am mainly interested in tropical bands and 49 mb SW stations, not interested in ham bands.

I have already got a Drake R8b but it is not good for DXing in these bands.
I have been reading in some web pages that the Drake r7A perfoms very well .
What is your opinion about buying a R7A or a similar receiver?
Of course I would sell the R8B first.
Any comments are wellcomed. Thanks

i think the aor 7030+ ia a good receiver am quailty is great also has a good
syc detector on there as well and of ssb is good all in all a good buy

I own both radios and I think the Drake R8B has an edge over the AR7030+
with side band selectable sync. They are both great radios.

I'm curious why you think the Drake R8B is not a good DX radio for 49
meters? What seems to be the problem? Overload from local MW stations?

The problem I have with the Drake R8b it is that I cannnot hear, understand, weak stations, because the audio it is too bassy and muddy.
Same happens on tropical bands.
I have tried listening with different headphones, audio filters but not improvement at all.
I think that this receiver has been made for generallistening not for DXing.
So, why did I spend a $1250 receiver if I cannot identify a weak station?
I have read in some groups that same thing happens in many R8B,s and the R8 has much better audio.

That's crazy. You can get plenty of treble if you move the PBT a little
bit.

Everyones ears are different. I have trouble understanding audio when it
has been digitally processed with artifacts generated by psycho acoustic
algorithms.

I used to own a R8 and traded it in for an R8B. I have not noticed a
problem with the audio sound having to much base with either receiver.

The two things you can do is turn the tone control clockwise for
increased treble and the other is use the passband tuning to bring the
higher audio modulation frequencies into the received passband.

If you are trying to use the narrower filters with AM mode that can make
the sound muddy. Use the narrow filters in SSB mode when DXing AM
stations.

If this still does not work for you then I suggest buying a professional
grade radio with digital filters in software preferably in the IF chain.
You will pay a lot more for it than the Drake.

Yes, I turn the tone control fully clockwise and move the passband tuning too, but I cannot get improvement in weak signals.
I have tried with a multi mode audio filter, a Datong FL-3, no results.
With respect to the antenna it is a Wellbrook 1530+.

Now, I hesitate in buying a R7A or a Collins 390A and to selling the R8b.

First of all, I'm glad that you are reconsidering buying a new
expensive radio. It won't solve your problem, since I had the same
issue with not understanding speech from weak tropical band signals
with my R7. I had a Sherwood SE-3 synch detector (your R8B has a
synch built-in) and ran the audio out to a good speaker, but still it
was too bassy. I thought about using a graphic equalizer to adjust
the tone. Here was some great advice I received on this forum years
ago:


"If bass rolloff is only what you're after. There is a
simpler way. Put a non-polarized capacitor between the R--7
and the speaker. There are numerous nomographs for picking
the right cap for your situation in most any radio
handbook. Audio handbook, too, for that matter. But you'll
likely want to cut and try anyway.

Its simple, cost efficient, and it doesn't require a ground,
so you can do it with most any radio."

I went to a Radio Shack and looked through the catalog for the low cut-
off frequency of different capacitors, and just attached one wire to
the capacitor on one end, and put the other end into the speaker.
Huge improvement. Experiment with different cut-off frequencies for
your personal taste, shouldn't cost very much and certainly cheaper
than a new rig.

It can get down to personal preference. I had a Kenwood R-5000 years ago
that I KNOW was superior to anything else I have ever owned,. Sensitive,
solid selectivity, many tuning and filter features, and like you, I
tried and built speakers, headphones and whatever else I could do. But,
I HATED listening to it after an hour or 2. Just something
psych-acoustic, whatever. I later got Yeasu FRG-8800 and after a
lightning hit, the FRG-100. Later, a Lowe 225. Admittedly, they might be
considered a notch down on qualiity, but the important thing is: I am
happy with them.
You might try tuning AM stations off-freq a couple Khz as your filters
may allow, to get the audio into the higher range, but this is not
really possible on SSB unless the Drake has a carrier offset tuning (as
does my FRG-100).
And, I really doubt if the AOR is any more sensitive than the Drake in
the real world, this sounds more like an antenna issue. Tropical bands
like long antennas.

Perfection? Hardly. Nice radios to be sure, but not perfect.

carlos2007 January 23rd 09 08:32 PM

Thank you very much for the non polarized capacitor advice, I will try it with a pair of RCA x33av speakers, and I hope it works with the headphones too.

I emailed Kiwa electronics two weeks ago asking if they have in mind or in a near future an audio upgrade for Drake R8 series.I have still not received response. I explained to them the problem and as I have read in some forums that many owners have it too.
I hope that the Kiwa consider it.
I made the Kiwa audio upgrade on the Degen 1103 and the difference it is amazing.

Meanwhile I will keep the Drake until I find a solution.

Thank you very much

Yes I am thinking about purchasing a R-390A to Miltronix, a full refurbished is about $2000 plus $500 shipping to my country,Spain plus $200 of incoming taxes.
http://www.dxing.com/r390/r390.htm

Does it worth buying a 390A or it would be better spend a little more money in a second hand Watkins Johnson or a Rhode & schwartz, for example?
