Regarding the Ultralight DX Awards Program (again).

jlochey <john.lochey@...>
 

Yesterday I asked a few questions about the Ultralight DX Awards Program...

I have yet another question (thanks in advance!).

Does the program only apply to AM DX'ing or also FM DX'ing?



Thanks,



JR


Re: MI LOG - FM

jlochey <john.lochey@...>
 

Byron,

Cool catches. I'm also from Michigan. We may have talked before.

Do you just DX FM or AM also?

Re: Nice review of the PL-380 by Radio-Timetraveller

Rik
 

I noticed he said in that review, the 380 still has the whip antenna connected on AM, and although it is not noticeable with just the short whip, a longer wire used outside does boost AM signals. I will have to try that on my 310, since I don't have a 380. It seems connecting one of loops to the whip did make some difference too.

Interesting! Thanks for the link- FARMERIK

My ultralights have arrived

neilbellgroups <neil.bell@...>
 

I just yesterday received a PL-360 and a PL-380. I opened the boxes and set both radios options where I wanted them. Now to do some testing and comparisons. I plan to start with FM reception testing, both with the whips and with a short 15 ft wire clipped to the whips. It will interesting and if you want I will post my opinions.

For AM MW I plan to wait for my 7.5 inch loop to be built and shipped to me.

Good luck with your Tennessee DXpedition.I live in Maryville near Knoxville.I have considered taking my Grundig G-8 up on one of the mountains near here and trying some fm dxing from there.When the opportunity presents itself ,I will do that.

I modified my loop with a larger capacitance variable tuning cap, 2 DPST

190kHz to 1800kHz by adding capacitance in parallel to the tuning
capacitor. This gives me a small portable loop for not only BCB DXing
but also LW non-directional beacon DXing. This doesn't allow me to
hear a 25W ndb from 2000 miles away, but it does allow me to log quite a
few beacons. CLB 216kHz, 270 miles east of here, is a regular logging.

My home in southwestern NC, is about 30 minutes from Mt. Pisgah, a
6000' mountain on the Blue Ridge Parkway. This has been a very good
DXing spot not only for AM BCB DXing, but also for FM DXing and I'll be
there again this summer for several mini DXpeditions. This will be the
first summer for ULR DXing.

Right now I'm compiling my ULR heard list which is slightly over 100
stations. With a little luck, it could be at the 200 mark or higher
after returning from Tennessee.

Re: Questions about the Ultralight DX Awards Program.

Gary DeBock
 

Hello JR,
 
Thanks for your questions, and welcome to the exciting world of Ultralight radio DXing!
 
In answer to your questions, you are free to use a passive loop of any size to boost the sensitivity of your Ultralight radio, and still have the loggings count for the Ultralight Awards Program. In such a case, the loggings would qualify under the "Unlimited Class," the category for DX logged on either a modified Ultralight radio, or one assisted by external antennas of any type (or both). This can include Beverages, Wellbrook Arrays, 9' tuned passive loops or other fanatical high-gain antennas.
 
A list of the currently-approved Ultralight radios (and their basic performance ratings) is contained in Kevin Schanilec's Ultralight Radio Gallery file posted in the Ultralightdx file section at    http://f1.grp.yahoofs.com/v1/8JEiTGgVx_zxBX-1FgGgOG3mRoiGnZPGfree1fmlyf6VeaXyWAwvvwM2Sk_-hmZefptGloNDpMGHcaeApm4Ao7ItTuc8JG4/1.%20Start%20Here/The%20Ultralight%20Gallery%20-%20April%202010.pdf . More detailed ULR performance information is contained in the annual "Shootout" files, posted in the same file section.
 
73 and Good DX, 
Gary DeBock (in Puyallup, WA)

Hey all,

I'm just starting down the road to ultralight'ing and working my way towards my first 100 stations heard.

I have two questions:

New Stations

Kirk <kirk74601@...>
 

Despite it being June, I've been fortunate enough to have bagged four new stations in the last week or so. The last two are detailed below and both logged on my Eton E-100 Slider w/ the ever-faithful SAT. I'm trying to catch up with fellow NOUDS (Northern Okla. Ultralight DX Society) member Richard Allen, but I have over 100 stations to hear before that happens, ha ha.

1540, KBOA, Kennett, MO, 0643 UTC, 6/20/10, hrd w/ adlt stnds mx on a program called "Music in the Night." Also hrd lcl ads and several IDs. G sig throughout reception. At 0702 I hrd a co-channel XE Sta (UNID) playing their NA but was down in the mud.

1020, XEOU, Huajuapan de Leon, Oaxaca, 0648 UTC, 6/22/10, finally caught clear mentions of "La Primera". Also hrd several Grupo Formula references. They play a variety of mx, including some ranchera, campo, banda, and pops. VG sig peaks and at times overpowering semi-lcl sta KOKP (Perry, OK). ULR Sta #666, LAm #109.

That's all from here, guys. No matter what band you're DXing these days, I wish everyone a DX-filled week. I'm enjoying reading abt all the Es lately. Sounds like fun. ROB ROSS: Congratulations on your FM sta # 2000! Wow!

upcoming shootout - DSPs immune to overload or not? (Re: K...

pianoplayer88key
 

Forgot a couple things...

How does the PL-380 behave when you couple the 9-foot PVC loop to it and point to (and tune) 1450 KSUH on the loop, then try for other stations on the '380 from Puyallup?

Also... when you go to Grayland, any chance you could try for some daytime groundwave DX with the 9-foot loop?  I know of someone who was able to get some Chicago AM stations from near Lubbock, TX (I'd link his site but it was down last I checked) at around noon, a distance of about 1,000 or so miles, so I think that comparable distances, or farther, may be possible with a loop like that, especially on a radio with a narrow filter like one of the DSP-chip radios.  I came up with a partial list of ideas...  (distances and headings are calculated from 46°48'4"N, 124°6'8"W.)

I don't expect you to receive all of these... but I'd like to know if you can get any of them in the daytime, and if so, what's the quality of reception?  I assume most of them would require the 9-foot loop just to get much of a signal.... and it's definitely possible that you would get co-channel interference from other stations in the same direction that are strong enough to be clearly heard using only the stock antenna on an ultralight with a sensitivity grade of "F".
Some of them are quite distant (well over 1k miles), but are included either because it's mostly a saltwater path to their location, or they're extra high power (although I did remove a few 500kW blowtorches that had close to a couple thousand miles of land to cross, and probably several stations on the same frequency along the path), for example.  Considering the saltwater path... is it possible with the 9-foot loop to hear any of the multi-hundred kW to megawatt stations from across the Pacific in the daytime?

Considering that I have been able to receive KNBR, KALL, KGO and KFBK at my location (near 32°45'40"N 116°56'50"W) at around noon using only a Select-A-Tenna (and PL-380, and for a few of those stations also on my RQ-SW20 which would be graded "F" on selectivity (local blowtorches on 690 and 800 are a challenge for those stations on that radio)), I would be quite surprised if your 9-foot loop doesn't completely blow the SAT off the planet... to the point where a signal that's completely undetectable on the SAT totally saturates (50dBu in blank spots across the entire band, 63dBu several harmonics up in the shortwave band, distorted audio on-channel like in a link I've posted previously) a PL-380 with the 9-foot loop. :)

My PL-380's minimum is 15dBu when not swamped by RF... and sometimes I've heard stations indicating 15dBu RSSI, 18dB S/N. That same signal would be completely undetectable when swamped by the 50dBu noise floor courtesy of a very strong station 100-200kHz away on my PL-380.

You're fairly close to 850 KHHO if I remember correctly, and 860 KPAM Troutdale, OR, shows as having a fringe signal, with you about halfway between the fringe and distant contour. Also, Grayland is in about the same signal range as KPAM, and has no nearby pests. Could you do a comparison of KPAM's reception quality from Puyallup vs. Grayland? Or would KHHO's IBOC wipe it out even on the PL-380?
> I will say, though, that your reception of KARR, based on Radio-Locator's maps, is impressive in the face of KSUH, considering how wide you say they spread on the SRF-M37V! I'm wondering... if I had a properly working PL-380... would I be able to hear 1290 KKDD from my grandparents' house in San Gabriel, about 1/3 mile from 23kW 1300 KAZN and 50kW 1430 KMRB? That location is right near KKDD's fringe. KAZN does have a minor lobe toward that location if I remember correctly, but it helps that neither station is IBOC (although there is a 50kW IBOC pest on 1110 5 miles to the east), and KMRB has a null in that direction. Also I believe the ground conductivity is considerably higher here in southern CA than it is there in western WA, not counting the salt water.

> My major 50kW daytime pest is 1170 KCBQ, 9 miles away. It is 63dBu on 1170, 43dBu with slight chatter on 1160 and 1180, and 41dBu with just static (but quieter static than normal) on 1150 and 1190. 1130 KSDO, despite being only 10kW, is about 6 miles away in the same direction as KCBQ, and is 63dBu on 1130, 40-41dBu on 1120 and 1140, and about 39-40dBu on 1110, nearly blocking reception of KDIS, a station I wanted to listen to without having to use an external antenna, and one of the original reasons I sought a different radio than what I had before.

> Yeah... I've been thinking mine's probably defective. I can understand having signals spread all over the place when I'm near a transmitter site like in the picture linked above, but not when the nearest transmitter is 6 miles away! How would you suggest going about replacing it? I don't know that I can really afford to buy another one right now... and last time (a few months or so ago - would need to check my sent folder) I emailed Joyce about something else semi-related I don't recall getting a response.

Off-topic: DX Clube do Brasil Gathering Video

huelbe_garcia@fastimap.com <huelbe_garcia@...>
 

Hi,

if you are curious about SWL and DXers gatherings down here in Brazil, have a look at this video:

http://www.youtube.com/watch?v=oF1Ew-Ovhmo

This was the "#10 Lorena DXCamp" organized by DX Clube do Brasil. Although in portuguese, the video has lots of nicely made shots and stills about our favorite hobby :)

Nice review of the PL-380 by Radio-Timetraveller

Gary Kinsman
 

Hello all,

Bill (Radio-Timetraveller) has posted an extensive review of the PL-380 on his blog.

http://radio-timetraveller.blogspot.com/

Based on his review, and the earlier review by Gary De Bock, I decided to finally buy one.

Regards,
Gary


PL-310 for $34.99 at anon-co

Gary Kinsman
 

Hello all,

I just purchased a PL-380 from anon-co. Joyce sent me a note indicating that the price on the PL-310 has dropped from $39.99 to $34.99.

I decided on the PL-380 because of the reduced soft mute.

Regards,
Gary

Looks pretty neat. It's also interesting that the hardware kits this works with use Silicon Labs' parts for their local oscillator (Si570/670).

I agree, the PL-310 is an amazing receiver for barefoot FM DXing. It's the same with the PL-380.

Good DX.

Dave Schmarder's Radio Articles

Gary DeBock
 

Hello All,
 
After winding about 24 plug-in 7.5" loopsticks for the PL-360 owners, my supply of 40/44 Litz wire was running out-- so it was time to order another 500' of the great-performing material from Dave Schmarder.
 
Dave is a great hobbyist very well known among the crystal radio enthusiast group, and he provides outstanding service for Litz wire orders, both large and small. He has supplied me with all the Litz wire used to modify countless ULR's, ICF-2010's, ICF-SW7600GR's, etc.-- probably miles of the stuff!
 
Dave was kind enough to provide this link to many interesting articles on his radio-related web site, which I hope will prove useful to many in our Ultralight enthusiast group:    http://www.makearadio.com/qsl/index.php
Thanks for keeping the ULR group well-supplied with hot-rod antenna Litz wire, Dave!! 
 
73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)
