[HCDX] RE: [LatinMWDX] A new radio !!!!!!!
Bogdan:
I doubt very much that you will find a used radio store that would know what
a ceramic filter is, or have a filter or know how to install one. I think
you will have to send the radio to one of the radio hobbyist companies like
Universal or Kiwa or ??
I don't think you should assume a filter can be added to your radio as there
may not be space and if there are already sensitivity problems an added
filter will just make it worse. Plus, ceramic filters are hard to obtain now
since Murata exited the business.
But in any case, I think it is time for you to quit trying to DX with radios
that are not DX radios. You are now seeing the problems of normal radios and
it will only frustrate you more in the future if you continue to be a DX'er.
Here's my idea: rather than spending some money on normal radios, can you
save a little money and spend a little more and buy a used DX receiver? I
wonder if there isn't someone on the lists that would sell you a used 7600
or CC Crane radio or maybe even a used older tabletop at a cheap price?

What do you think would be the cheapest option ? Repair the Sanyo MCD-S830
tape recorder or put a much narrower filter in the other more new Sanyo
receiver that we buyed today from an used radio shop ?
Good night,
Bogdan

Finally, it isn`t as good as I thinked; the sensitivity on the higher
part of the AM band seems better than that of my old Sanyo MCD-S830, but on
the lower part of the dial it`s totally the opposite. I can get the
poor-fair level semi-local WEVD with my Sanyo easily, but not at all with
the "new" Sanyo receiver (another model) (with CHLN nulled, I hear nothing
on 550, in the day-time !).
Also, when I analysed very fast the AM dial this afternoon, I thinked it
would be a fairly selective receiver at least for 10 kHz spaced Latins and
to some extent strong Caribbean splits next to not too strong even-channel
domestics (like ZIZ on 555 with CHLN nulled and with weaker WEVD and the
Rhode Islands`s Radio Disney outlet here). Well, I was totally wrong, in my
very fast tuning. I can get weak, but still annoyng overspills from local
CINW 9-40 News on 910 where I used to hear regularly WABI out of Bangor and
also used to hear but not identified yet on a fairly regular basis YVRQ with
my Sanyo MCD-S830 and this despite the MCD-S830 wasn`t too sensitive in the
800-1000 kHz area.
Also 970 is completly covered by splatter from both 940 CINW 9-40 News
and 990 CKGM The Team, and on my Sanyo MCD-S830 I could very easily get WZAN
in Portland, ME almost without any next-to-adjacent het, let alone next to
next-to-next-to-adjacent one.
The biggest problem however is crossover modulation and splatter from
very strong major international SW broadcasters. For exemple when I tune
accros WTOP-1500, around 1498 or 1499 on the lower side of their frequency,
I can pick up something like Radio Netherlands in an exact place; I can`t
really tune them, because it escape tuning, then I tune to them again and in
a few seconds they pretty much escape tuning again; it`s the same effect
that I have noticed since about 1998 on our Venturer AM-FM clock radio, on
the AM band.
However, being a very senstive receiver, there is still a solution as to
keep it; going to a repair shop and changing it`s filter and put a narrow
one that will reduce at least the next to adjacent local splatter (for
exemple stopping hearing very slightly distorted and very comprehensible
CKGM-990 splatter on 970 killing a really great DX channel as well as some
third adjacent CINW-940 splat.; also 710 is a very interesting channel where
I tentatively received YVKY Radio Capital once, and CINF and CKAC are
hammering severely on it). And, other than the annoyng next to adjacent
local splatter that kills a lot of Latin American DX, there is the pretty
severe intermodulation from very strong SW signals that I CANNOT tolerate,
and a narrow filter will filtrate those ghosting shortwave signals, I think.
On the other hand, I heard slow-tempo Cuban music on 640 kHz with a poor
and fading, but more or less listenable signal out of Radio Progreso-Cuba,
as well as what sounded like threshold Radio Carupano over a very threshold
WBT just before going to bed at about 6 PM, so it proves that with a
narrower filter, this can be a killing DX machine !
Well, that`s it for now !
It`s almost 2 AM and I have to go to bed, even though I sleeped this
late afternoon / early evening 3 hours and a half beetwen about 6:00 and
9:30 PM. Because of the intermodulation and way too severe and annoying
next-to-adjacent local splatter, I spent most of the evening downloading
music on Kazaa on burning on a CD the Uriah Heep`s 1985 album Equator wich
do have a lot of 80`s hard rock, heavy metal and new-wave as well as 1 or 2
soft-rock songs on it. It`s my favorite Uriah Heep album; definitively much
more synthesizer than most of what they have done during their classic
period in the 70`s, for those of you that know them.
73 and good DX,
Bogdan

We did go at a shop with old radios this afternoon and we buyed an old
Sanyo radio (a bit different from the Sanyo MCD-S830 but with pretty much
the same sensitivity and selectivity carachteristics, so I will be able to
tape my DX sessions and to DX on a good radio with a good internal ferrite
bar antenna that can null out west-east North Americans and pick up Latins
from the south again starting this evening. During the day-time, this radio
picks up a lot of semi-locals like CFRA Ottawa. The only problem, is that
despite the fact that both the sensitivity and selectivity are very good,
the nulls of the ferrite bar antenna are very slightly less sharp than those
of the Sanyo`s ferrite bar one; for exemple I can`t really completely null
out CFRA and it is just a SEMI-local, not a local. With my Sanyo I could
null 99.9% of it and only detect it as a kind of extremely weak het in the
sharpest null. This is because the ferrite bar antenna is of a much little
size (I have to actually orient my radio EAST-WEST to pick up what it`s
north and south of me and vice-versa), but the probably higher sensitivity
compared to the Sanyo MCD-S830 more than makes up for that. I could replace
it eventually with the Sanyo`s ferrite bar, but for hearing strong Latins
like Coro-780 wich is really strong during Auroras and WBBM is almost always
completely during such condx, so it`s nice !
73 and good DX,
Bogdan
