XHDATA-808 & the AR-1780

Troy Riedel
 

Are the XHDATA-808 & the AR-1780 radios accepted as meeting the group's "Ultra-light" definition?  Just curious because both, based on manufacturer specs, exceed the Cubic In. criteria of 20" or less.

XHDATA-808:
5.71”
3.43”
1.06”
Cu In: 20.76”
 
AR-1780:
5.9”
3.7”
1.2”
Cu In: 26.2”

Thanks in adv.

I guess (and I might be wrong) that a SDR which fits the ultralight guidelines would be accepted. Nothing in the guidelines talks about the receiver type, only size and cost.

Jokes aside, i was only thinking in terms of the old/traditional SDR that you needed an external hand from a computer. The small sDR receivers you mentioned are indeed changing the game on SDR and slowly creeping in the ULDx space, with one of the few examples Jorge gave.

So yes, maybe with the advent of portable SDRs it should be about time to re-think the concept of UPDx machines, or then maybe, define its canon and instead of including, excluding devices might be the way to go.

Precisely. Perfect fo SWL, and for FM. AM i think i need to get or make an antenna. :)

Hi all,

As new radio purchases are always exciting and difficult to explain to "non-radio" people, I thought I'd share with the group.

New additions to my UltralightDX team are:
  • C.Crane Skywave - Love it!  Just got it yesterday, so still learning it
  • Sangean DT-800 - On the way, but seems nice
  • A Vonidor cheap AM/FM "old school" radio - Vonidor
  • A PowerBear cheap AM/FM "old school" radio - PowerBear
  • Also purchased a rotatable turntable to use with my Tecsun AN-200 loop antenna

Thanks for sharing my excitement!  :)

Re: Couple new radios on the way!!!

I just got my PL-330. I'm finding the best way to use it as I hate the soft mute but its better 1KHz off frequency (sometimes 2KHz!) or on sync. The very small STEP and ETM buttons I cut a matching piece off a fine heatshrink put a smidge of superglue on the button so keeping it black and raising it above the surrounding plastic of the display. Actually I put on 2 layers and the buttons are much easier to use now. I also bought a higher capacity battery and a charger. All set for serious portable listening in the park (low noise) now I hope.

For a long time I have been looking for a way to log and store my ultralight DXing related information. Of late I had been using some paper log sheets and then transferring these to my custom database program on my laptop.

After using this method for the past year, I decided I was sick of the "double handling" and the errors / time delays this can bring. I was also finding that I was getting behind with my logs. Recently I was looking around and found this great (free) app for Android called PortoDB. I have now installed this on my phone and have setup a database.

Re: Barefoot? "Modified" ?

Jorge Garzón <iberiaDX@...>
 

Hi John, 
"Barefoot" would be most likely the receiver itself with its own antenna, no external 'help' at all. On FM the whip/earphones; on MW the ferrite built-in.

"Modified" as you pointed, means "anything modification goes", addig a new larger ferrite bar but, could be add under "modified" the use of an external antenna (a larger loop, an FSL and so on)? That would be actually an "assisted barefoot" when the reception is just by coupling an external aerial and not by direct connection. 

Uhhmmm, thinking on that! 🤔

hi 
The next step is a C.Crane Twin Coil Antenna best mounted on a TV Antenna Rotator (that displays Direction) located outdoors away from the building's noise envelope. Try finding one on eBay.

Re: FM DX? AM DX?

I do whatever DX that land I’m on gives me the advantage to do. When I lived in NW Pennsylvania I did exclusively FM DX, because I was on the highway residential point For 200 miles

In Alaska now, I so AM in late fall to early spring and shortwave outside of that with incredibly Outstanding results

Re: WION 1430 Stereo TESTING TONIGHT

DX Pedro
 

Nice initiative to be share. I won’t be able to listen here in Portugal, but I’ll bet some y’all that side of the pound, will help the station with its tests.
Have a great weekend.

WION 1430 kHz in Ionia, Michigan will be testing tonight. The purpose is to evaluate the matching of their night directional array to their transmitter. This will help ensure better bandwidth for their C-QUAM AM Stereo signal.

The signal will alternate between the night time power of 330 watts and their daytime power level of 4.7 kW starting at 11PM EDT and midnight. (0300 UTC) The duration of the testing is unknown, but probably not more than a couple of hours. Daytime power levels will occur during the experimental period so after Midnight EDT (0400 UTC). All transmissions will occur using their nighttime antenna pattern: 

WION AM Coverage Map

The station will mostly transmit their usual mix of music, but there will be some sweep tones designed to measure the transmitter performance and voice identifications. 

You can compare your reception to their live web stream which is at: 


See a more detailed listing of the testing tonight from their Chief Engineer Greg Buchwald below: 

Author
Update: The updated AM stereo tuner is now online. Less top end distortion. (The Carver needs alignment and probably a few caps changed). Carver tuners, with out a modification on the stereo decoder PLL also have increasing distortion on the bottom end around 50/60Hz. We ran an hour of difficult test music and confirmed it is working properly. Tomorrow night we will take the AM down to measure the night directional array network and finalize the new matching of it to the transmitter for better bandwidth. The current night array is 10.5dB down at 1440khz as compared to the lower sideband at 1420khz (10khz modulation). The resultant quadrature distortion equates to well over 10%; dropping to 4% at 5khz. I expect this to be well under 1% when we are finished. Saturday night is prep work only. We need final measurements to lock in some capacitor and inductor values. I expect the installation of the network will occur in June. After an hour measurements, I will do some audio work. The music will not be your normal selections; it will all be highly separated and chosen to really test the system and allow us to evaluate some minor component changes in the optimod processor and the CRL AGC that precedes it. Comments will be welcomed. Specifically to the DX association that wants to do some listening tomorrow night: carrier will be up and down at 4.7kw and 300W. I can't give specific timing of each power level but expect us to begin sometime between 11pm and midnight edt. There will be few if any tones as we will actually sweep the carrier frequency for some of the tests. Once we have the required data, I will run some tones to confirm the transmitter performance. That will be followed by extended music sets while we perform the audio processing mods and updates. When we install the network at a later date, it will be much easier for us to state specific times of carrier power levels and specific modulation.

Expect lots of reports and discussions on the Facebook group devoted to AM Stereo: 


Greg has discussed the possibility of a DX Test using Morse Code, sweep tones, etc. in June when the station will be doing additional testing during experimental hours. Stay tuned for that event. 

The CPC is not coordinating reception reports for tonights events, but we would appreciate receiving .MP3, .WAV, or .MP4 video recordings of your receptions. Send those to:
