[HCDX] Re: [LatinMWDX] A new radio !!!!!!!

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

  Subject: [LatinMWDX] A new radio !!!!!!!


  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
