PL-380 Version 2?

J P <deafasabeetle@...>
 


Hello From Australia,

First post to the group!  I've just added a PL380 to the collection.  I also have a PL-300WT.  Both receivers are excellent.  With regard to the post about a possible new model of the PL380 I notice that the end cardboard flap that the RX came in has the following printed on it - '2009.9 Ver.2'

Anyone else got this?

Re: G8 signal strength meter

sdwillingham
 

Jim gives an excellent explanation of the RSSI and SNR indicators.
Here are some further comments for more technical readers.

1) The abbreviation RSSI stands for "Received Signal Strength
Indicator", not "Relative . . ." Jim correctly emphasizes
that this strength refers to the LNA input voltage, not
electromagnetic field strength.

2) The signal-to-noise ratio Jim describes refers to signal strength
compared to the noise generated by the radio circuitry. The SNR
metric from the Si4734 is more sophisticated than that. If one
substitutes a short-circuit across the AM antenna terminals, he
will see the RSSI drop to 2-5 dBuV. With an antenna connected
and "between stations", the RSSI can be 30 or more dBuV. Yet the
Si4734 does not report the SNR as 25 dB, i.e. the signal strength
above the receiver noise floor. Instead, the chip reports a
metric measuring the signal strength relative to atmospheric
noise and interference. Of course, if the atmospheric noise is
low enough (or antenna gain is inadaquate), the SNR calculation
will reflect the receiver circuit's noise floor. I wish I
could give more detail about the calculation, but I believe that
is proprietary information.

NEW XE 830 kHz

Kirk <kirk74601@...>
 

Hi Gang,

Haven't been doing much radioing lately, so I decided it was time to try my hand at it again. I did find another new XE on 830 w/ quite a few other XE stations including XELK (ID hrd) and WFNO. At times I think I may be hearing up to 5 SS stations at the same time on that channel...gets a little tedious there sometimes, but I'd much rather deal with a pile-up than no stations present at all:) Hrd on SRF-59 w/ SAT.

830, XEIK, Piedras Negras, CO, 0103-0130 UTC, 1/27/10, as best I could tell this station was carrying mostly all tlk from Grupo Formula. Many Formula IDs hrd. They occasionally broke away for lcl ads, and I caught one call ltr ID. As mentioned, up and down w/ a slew of other stations.

That's it from here for now. 73 to all!

The decibel is a way of representing the relationship between two electrical quantities of the same type and units. For example, you may be comparing two powers, two voltages or two currents.

The meter on the left compares the voltage across the input to the LNA to 1 microvolt (uV). On AM, FM or SW, the radio's antennas are not efficient, and their response is not uniform across any band. The signal strength required to generate 1 uV on one frequency may be much different than that at another frequency. So the meter is not absolutely accurate for comparing signal strengths on different frequencies or bands. You couldn't accurately say, "WGR is 10 dB stronger than WWKB," because they are on opposite ends of the band. Thus, it's called a Relative Signal Strength Indicator (RSSI).

The meter on the right is marked "SN," an abbreviation for "Signal-to-Noise." This is a misnomer, as the proper term is "Signal-plus-Noise-to-Noise." In testing and comparing receivers, this measurement is done as follows: The receiver output is connected to a meter. With no signal applied, the noise output is measured. Then a signal of known strength is applied and the measurement is taken again. The noise measured at first is still present, thus "signal-plus-noise..."

On a PL-380 (and I assume PL-310) where you can adjust the selectivity, for a given signal strength, the SN meter reading should increase as you narrow the bandwidth. Noise is aperiodic; that is, it is random in frequency. You can hear the reduction in noise on an unoccupied channel when you decrease the bandwidth. For a given, constant signal level, reducing noise improves the "SN" result.

If you can increase the signal level without also increasing the noise, or if you use an antenna that, while it may not pick up as much signal as the internal one, reduces noise pickup even more, you can improve the SN number and make the signal easier to hear.

In actual use, however, the meters are not so helpful. That's because they don't respond quickly to changes in signal level. The reason is the need to reduce processor functions that would drain the batteries more quickly, and could increase digital noise radiated into the antenna.

Hope this helps. You can learn more about decibels from Wikipedia. To narrow the bandwidth I skipped over how they are calculated. :)

Hey Jim,

Your right on WRCA is in Mass. I don't know why I wrote NY, it was late when I wrote this so I was a little tired. But thanks for showing WCRA on 1090, I guess in my rush to write down info I swip-swaped two letters. But I hate to say it but I'm still suspicious of whether or not thy were one the Air. I looked on their Web sight just to see that 5pm they have Bill O'Reily till sign off. If it's a 3Hr show the time doesn't add up. For Sign off would be around 8PM local. I logged them around 9:30 PM local.

I'm going to shoot them a E-Mail and find out whether or not they really on the air at this time.

But can you believe that I caught KAAY, after what we discussed early last year?? I got all these funny bruises on my face, because I keep pinching myself!!:o)

But thanks for all your help I do appreciate it, for sure!!!

Thanks,

Well what a difference a day makes!!!! I reported that the night before I was having trouble verifying a logging where I thought, I heard WRCA on 1090 KHZ in the 2008 of the RCA AM log book it listed it as a daytime station in Effingham, IL.

   Problem is that the FCC's AM Radio Query shows that WRCA's on 1330 KHz in New York state!! I then put in the call sign in the search engine and I was taken straight to their web site. So now I'm really confused and frustrated, so the logging has been struck from my log. BUMMER!!! :(

  So as I left the radio on 1090 KHZ, when I called it quits for the night. The next evening at local sunset, around 1700 (L) this time of the year, I turned on the radio, still on 1090 KHz,  I heard a woman preaching in the Southern Baptist style. The audio would be very good at first, then wash out in a wall of heavy static. As the BOH came around at 2222 UTC, the audio came back strong, just to hear something made me practically do a back flip !! A very clear ID of KAAY!!!! In my hunt for states heard award, I was obsessed that I couldn't get anything from Arkansas. Most of the stations in the state are relatively low power and leaving KAAY as the only powerhouse station, but it's radiation pattern left much to be desired in rearguards to Ohio. KAAY's major lobes are pointed N-NW to S-SE. And all attempts to log anything failed miserably. But low and behold something happened propagation wise last night, and I caught it!!! I'm still pinching myself. But that wasn't the end.

    As I was tuned, around I caught WTAM on 1100 KHz in Cleveland, OH, one for the ULR heard log, but nothing earth shattering. Then I tuned to 1110 KHz, I heard a good signal with a "rewind" of the Clark Howard show. As the station ID at TOH (2300 UTC), came around, My mouth fell open,................ KFAB, Omaha, Nebraska!!!!! :) Talking about lightning striking twice!!! How could I get so lucky??:) :)

  So that raises my state count to 22 states heard. As I mentioned earlier that I struck the WRCA" off the log, and I have another logging thats a trouble maker. I logged WLOD on 1140 KHZ playing  a sysyndicatedountry music show called "The Road". Problem is the RCA Log and FCC Query show it as a Daytime only, 1 Kw with religious format. Trying to look for WLOD's website shows it's website is down. So does anybody know more if the station has changed operating hours and format??

   Then I caught WCFO on 1160 KHZ, out of East Point, Georgia. I looked up WCFO and again both publications show it as a daytimer, but when I looked up the stations website, it shows they operate 24 Hours, 7 days a week. The only thing a miss was the show schedule was supposed to be a bubusinessalk show.But it wouldn't be the first time, some body didn't show up to the studio so they put a "canned" show in it's place.  But I'm very confident that I'll claim this one as verified.

   So I got a couple others so I give it to you from the top............

Big hets tonight!

jim_kr1s <jkearman@...>
 

Was listening to CMDL R26 in Matanzas on 1060 about 0215Z  when this huge het appeared. Tuned up to 1062 but the whine was very strong. Will process the recording tomorrow. It went down about 0245Z and is now weak. The big choices are Turkey and Denmark, and it's about an hour before sunrise in Turkey (300 kW; Denmark is 250 kW). Had to skew the bearing to null Cuba so can't say for sure.

Down on 970, another het appeared, looks like Germany on 972. Recording now, with fingers x-ed.

I'd be interested in knowing if the TP path also opens tomorrow.

All this other stuff is getting in the way of Operation Bay of Sigs, but there are a few more Cubans in the bag. One minute I'm logging them, the next I'm trying to null them. The turntable is getting a workout!

The New Awards

John H. Bryant <bjohnorcas@...>
 

Thanks to those who commented on the beauty of the new award - the Centurian - and the other awards, too!  I think that most of us enjoy the Radio Art of the 20s and 30s, when radio was young. I love the best of them! Since many of these images are approaching 90 years old, the images are happily in the public sector and we may use them guiltlessly.

If you enjoy these images, why not collect a few??? All you have to do is mine your ULR log book and prepare simple submissions for ol' Rob Ross ( )to review.  He does that and shoots a list of approved submissions to me.  I make out the certificates and e-mail them to the recipients.  It literally could not be cheaper.... its free and fairly fast.

Me. I'm going to work on DX Centurian: Oceania, DX Centurian: Asia and (god help me) DX Centurian: Texas.

So keep those cards and letters  coming.... to Rob!

Re: L/C Meter Project

Roy <roy.dyball@...>
 

Hi Jim

Thank you for the prod. You were correct the first time.

When I checked the series current at the battery it was 1.6A. No wonder it was hot. I cut the trace from the regulator output on the board and measured the current with the load removed, with just the regulator in circuit. The regulator was only pulling 2MA and happily sitting on 4.98V. The L/C meter had to be pulling 1.599A. It hit me immediately what was going on and it was my fault.

When I built the kit there was 3 X 100k resistors missing. Also a mystery 1.5K resistor was left over. I assumed it was to go in the position for R1 because there was no resistor supplied for this, R1 showed on the circuit as 15K. This resistor goes to pin 15 of the LCD and controls contrast. I had compared other circuits on the net and saw that a pot had been used on pin 15 to control the contrast. It seemed plausible because a non standard value of resistance was specified that someone had just measured the pot and substituted a resistor to keep the cost down. So I just used the mystery 1.5K in its place and when the project worked so well and the contrast looked good I did not give it much of a second thought.

The first thing I did was to unplug the LCD display module and measure the current drawn by only the processor and oscillator, it was under 10MA.  The next thing was to disconnect the mystery resistor and reconnect the display. The current drawn from the battery now read 100MA and of course the display was blank. This wrong choice of resistor was responsible for chewing up 1.59A. I cobbled together a 6.8 and 1.5k in serries to make a 7.3k resistor as I did not have two 15k to put in parallel. The current still read 100MA and the display looked terrific and had good contrast.

I still was not happy because the regulator was slightly warm and the specs said it should only draw 10MA and my kit was still using ten times the current. The suppliers had noted that they had supplied a bonus back lit LCD. I found the series resistor that feeds the LED (R5) a 10 ohm resistor and immediately thought that the value was too low for a serries LED resistor at 5V. I disconnected it and the total current drawn by the fully working L/C meter was 10MA. I like the back light but I think I will switch it and experiment with a different value for R5 to reduce the current. The regulator is now running as cool as a cucumber and I am happy with the 160 times power reduction.

Roy.
