Re: Tecsun PL-380 "Soft Mute" (or lack thereof)

Larry Fravel
 

Your discussion about the "new" models prompted me to check my PL-380 that I received from Anon in mid December. The serial number is:
 
3692009 000333  Mfg Date 11 09
 
It has 2 screws in the battery compartment.  WIthnthe DSP set to 1 khz. and tuning slowly in 1 khz. Steps (I used 1310 khz which has no local) stations I did notice that the RX audio did seem to drop but did not disappear completely.  This was done using only the stock loop stick and sitting in the living room.  I live in a rural setting and have no interfence unless it is "house" generated. In fact the radio is within 12 inches of an HP 22 inch LCD Monitor and no noise from that source. Right now I'm listening to a Spanish station I will try and ID later.
 
As far as SW and LW I haven't tried yet.
 
Hope this helps a little.

Re: Tecsun PL-380 "Soft Mute" (or lack thereof)

Gary DeBock
 

Hi Mike,
 
Thanks for your comments, which sound logical to me.
 
Since Joyce is probably not an expert in Tecsun radio design, however, the best option seems to be specifically placing an order with Joyce for a "new design" PL-380, then checking the DSP filter options on this new version, and stripping it down (as Roy suggests) to check the labeling on the DSP chip. This "new version" PL-380 order will be placed tonight, with the EMS shipping option.
 
73 and Thanks, Gary

Since Joyce is the one who mentioned this 'version 2', why not "go straight to the horse's mouth" and, simply, ask her what the difference is? ... rather than all these attempts to infer what the difference(s) is(are) ... via empirical observation?


Re: Tecsun PL-380 "Soft Mute" (or lack thereof)

Gary DeBock
 

Hi Roy,
 
It really seems that Tecsun didn't change anything with these three PL-380's, since the filter selections, filtering performance, and the ability to tune 1 kHz up or down from a weak station (without a severe soft-mute drop-off) is exactly the same as my earlier PL-380 models. I don't know if these are the official "new model" PL-380's (mentioned by Joyce of Anon-co), or not. Nothing seems different to me.
 
I plan to perform some loopstick modifications and other experiments on these models, but since two of them are destined for other DXers after thorough testing, I'll save any strip-down work for the model I plan to keep. It may be the weekend before I can do much with them, however, since my Amidon shipment (with the LW-optimized ferrite bars and shorter type 61 bars for the PL-310 internal loopstick tinkering) apparently hasn't even shipped yet. Amidon certainly must be wondering how so many orders came suddenly, despite the poor economy :-)

Hi Gary

Perhaps the new 380s have the new Ver40 firmware. You would have to strip it down and remove the RF shield from the Si4734 to read the top of the chip to find out. Are the filter selections the same?

Re: G8 vs CR-1100 preliminary AM BCB report-FARMERIK

Gary DeBock
 

Hello Farmerik,
 
Thanks for your message.
 
The CR1100 units were obviously designed for the Chinese domestic market and can be set to tune in 9 kHz steps, but the neither the poorly-written English manual nor the Chinese manual mentions how to do this. The Chinese manual says that the steps tune in 9 kHz increments, and the English manual say that the steps tune in 10 kHz increments. Lots of help, right?
 
But even if the CR1100 model here could be set to tune in 9 kHz steps, this would hardly transform the radio into a prolific TP-chaser. The Si4734 DSP filtering is fixed at such a wide setting (my guess is 4 kHz) that domestic splatter would almost always cover any TP's that show up. Because the radio will not tune in 1 kHz steps, there is no way to get 1 kHz farther away from splatter (like with the PL-380).
 
If you still don't have an English manual for your CR1100, I would be happy to mail you mine for free (if you can give me your snail mail address). Both my wife (from Hong Kong) and I can read Chinese, so the more detailed Chinese manual is the one we would use. Unless someone else wishes me to scan and post the English manual, I'd be happy to mail it to you.
 
73, Gary

If the 9 Kc. steps were selected, would it be on frequency for the trans ocean signals?

I am disappointed the loop stick is not larger.

I did not get the English manual included. I emailed Amazon, and they said contact the MFG. Since the controls are in Chinese, I thought perhaps Kaito wrote the manual, so I emailed them. No answer, but it's a Holiday week end here. You don't have the CR-1100 English manual scanned do you? - FARMERIK

Re: MI log

Gary DeBock
 

Hello Byron,
 
Actually there have been several DXers who have replaced the tiny tuning thumbwheel on the SRF-59 (and the very similar analog SRF-39FP) with a large vernier drive tuning system. John Bryant did this with his "National SRF-39FP" modification, with the article posted at http://www.dxer.ca/file-area/cat_view/87-ultra-light-radio-files-area/95-ulr-radio-modifications?start=10 . John used a 5:1 reduction drive tuning capacitor from the National Radio Company.
 
This modification (as well as adding almost any other new components to an ultralight radio) would place the radio in the "Unlimited" category for award purposes, however.
 
73, Gary

the new SRF-59 has a much lower noise floor than any of my other receivers, but its much harder to tune and to know what freq i'm on. so i have to use a spoting receiver. anyone notice, its made in China ! sure would like to put a big ol vernier drive on it. 36 to 1. wonder if that would still be considered unmodified? ever tried that Gary ?

Re: Tecsun PL-380 "Soft Mute" (or lack thereof)

Roy <roy.dyball@...>
 

Hi Gary

Perhaps the new 380s have the new Ver40 firmware. You would have to strip it down and remove the RF shield from the Si4734 to read the top of the chip to find out. Are the filter selections the same?

Tecsun PL-380 "Soft Mute" (or lack thereof)

Gary DeBock
 

Hello All,
 
For those interested in whether the newer PL-380 models have the irritating "soft mute" function disabled or not, a recent shipment from Joyce at "Anon-co" may be of interest.
 
For experimentation (and for forwarding to other DXers), three PL-380's were ordered from Joyce on December 29th. She kindly upgraded the shipping to EMS (express mail) at no additional charge, so that the radios were received today.
 
All three of the PL-380's were manufactured in December, and all have two screws in the battery compartment. The serial numbers are also similar: 
 
36920091200993
36920091200998
36920091201009
 
All three were tested against a soft mute-enabled PL-310, to see if there was any difference in the soft mute performance. Similar to the other two PL-380 models here, tuning the new PL-380 models 1 kHz up or down from a weak station's frequency did result in a reduction of signal strength, but it was a moderate reduction, not the very steep drop off in audio like on the PL-310. This was with the DSP filtering set at 1 kHz (typical in TP-DXing). The PL-380's were also checked for intermittent signal drop out during weak station reception, but did not have this soft mute-related issue, either.
 
Whereas one of the first two PL-380's received here had instability on the SW bands (with intermittent oscillations, as reported in the PL-380 review), all of the three new PL-380's have stable SW reception. One of the new models does have a tuning control which seems slightly stiff, however, and one new model seems to have slightly lower AM sensitivity than the other two (I suspect a loopstick issue, which would make this model a nice candidate for a transplant :-)
 
In general, there doesn't seem to be any real evidence yet that Tecsun is changing the PL-380's to the full soft mute mode, but any DXer receiving one of the official "new models" is requested to notify the group ASAP if soft mute changes are suspected.

Finally !
The western MI stations disappeared and 1660 NJ was in the clear, lots of Korean language, then exactly at 1800 EST, a tone sounded and in English the station ID:

1660 WWRU Jersey City NJ, Jan 04 1800 EST. 478 mi.

First time I ever heard a tone before the ID.
Their signal is beamed south east at 10 kw

Latest DX - Monday 04 Jan 2010

Stephen Ponder <n5wbi@...>
 

I'm still having problems trying to fall asleep at night. Guess I'm
not fully back on schedule yet. Anyway, I tried to see if I could get
anything on my 630 kHz UNID from the night before, but zippo. So, I
decided to channel-hop to 640 kHz and then later to 660 kHz. Here's
what I heard ...

640 kHz

04-JAN-10 0128 CST WWLS Moore OK "AM 640 WWLS The Sports Animal" and
into ESPN Sports

660 kHz

04-JAN-10 0157 CST KSKY Balch Springs TX "AM 660 KSKY" in the outro
of a pre-recorded Dennis Prager Christmas show.

Both were heard using my DT-400W barefoot. These are both new to my ULR
logbook, but not to my "old" log.

73 and God Bless!

I'll be happy to report what I find when my PL-380 arrives (likely in
2 or 3 weeks; fortunately, I'm on the West Coast so I imagine that will help
arrival times a bit). So far, open questions are:

1) Is there soft mute? (probably la pregunta más importante)
2) How many screws are in the battery compartment? (maybe)
3) What's the serial number?

¿Todo lo demás? (Anything else?)

Hello Michael,

Thanks for your question.

Both the PL-310 and the PL-380 have the loopstick coil turns glued to the
ferrite bar (without a coil form), so there is no possibility of sliding a
coil for alignment purposes, such as in the R911 and R9012 models. The same
is true for the Kchibo D92L and D96L models. In the PL-300WT and G8 models,
however, there is a coil form which can be slid (after some glue has been
removed), providing an inductance-matching system which has improved AM
sensitivity in some models (although the final results will still be modest,
in comparison to the more sensitive Si4734 models like the D96L and PL-310).

For a DXer interested in great reception of North American stations, the
PL-310 would have a lot to offer. It has very good AM sensitivity, and also
has the 1 kHz DSP selectivity necessary to greatly reduce splatter from
strong local stations. Unfortunately it also has the "soft mute" issue, which
causes audio on weak stations to drop in and out on occasion. The PL-380
models (at least the older ones) appear to have the soft mute either disabled
or reduced, but the loopstick is smaller in these models, causing a drop
off in AM sensitivity (relative to the PL-310) on most AM frequencies.

A detailed Shootout of the PL-310 and PL-380 is contained in the recently
completed PL-380 full review, and discusses the tradeoffs in choosing these
two models. It is posted in the Ultralightdx file site, on dxer.ca's ULR
file section, and linked at _http://www.mediafire.com/?w4yuzhj2kyz_
(http://www.mediafire.com/?w4yuzhj2kyz) . I hope this will be of assistance to you
