[IRCA] Chinese Analog AM Portable Craze
Hello All,
The first wave of the Chinese analog portable invasion has hit the west
coast, and the Tecsun-manufactured models like the R911, R9012 (and others) are
being received eagerly. DXers are having fun nulling out their semi-locals and
even locals, receiving other stations right on the fundamental frequencies.
For those of you who have ordered one of these extremely cheap (around $10,
or under $17 shipped) but highly capable portables, here are a few tips to
help you get the maximum performance.
1) Place the whip antenna in the vertical position, before attempting AM
DXing! This is EXTREMELY important in obtaining maximum sensitivity!
2) Perform the alignment procedure according to the pictorial uploaded to
the Yahoo group site "Ultralightdx," in the photo section ("Chinese Analog AM
Radio Alignment"). The procedure is extremely simple, and will help you not
only get maximum AM sensitivity and selectivity, but also have coverage extended
to 1700 kHz.
3) When using these radios' amazing nulling ability, use the tuning LED
control to ensure that the local is fully nulled. When the LED goes out
completely, the local is nulled. Tilting the radio slightly can sometimes improve
nulling of the local.
4) Although locals and semi-locals can certainly be nulled in the daytime,
your chances of receiving another station on your pests' frequencies increases
at night, when the pests can have serious competition.
5) When fully aligned (AND with the whip antenna in the vertical position),
these radios typically have sensitivity and selectivity comparable to the Sony
SRF-59 and SRF-39FP analog models.
5) By the way, these $10 radios also receive FM, and have multiple SW band
coverage. Be thankful for the demographics of the Chinese domestic market,
where Tecsun finds it profitable to sell these highly capable analog radios for a
ridiculously low price.
73 and Have Fun,
Gary DeBock
