A Special Mid-Week Ultralight DXing Award

John H. Bryant <bjohnorcas@...>
 

Yes,

You guessed it!  Rob submitted his list of 800 Stations late yesterday to become our first holder of the Heard 800 Stations award.  His award is in the Unlimited category, but most of the receptions were Barefoot, with a distinct minority using an inductively coupled loop.  In any case, with whatever antenna, hearing 800 different MW stations with one of these little things is not only unprecedented, but it just flat boggles the mind.  Wow!!!  A lot of hours, a lot of talent and an amazing little radio.  BRAVO, Rob, and thanks for being such an inspiration for the rest of us.

Thanks, too, for all that you do to service the Awards program... we could not do it without ya....

Rob got his award early this morning, about 1300 UTC.

for The Awards Committee

An extensive group of awards certificates is available from the Ultralight MW DXing Awards Committee. Each recipient receives a digital file which may be used for electronic display or is suitable for framing when printed at 8 12" x 11" on good quality paper. Information on the Awards Program and the simple application procedures are found in the Downloads>Ultralight Files>General Information area of dxer.ca and our own file area here at ultralightdx. Applications go directly to Rob Ross

Rob:

I'm further behind than I wish. After achieving 700 I concentrated on trans-oceanic DX with limited success. Finally, this evening I broke a long drought and logged station #743, catching a few seconds of ZNS1 on 1540 kHz at 0018 UTC. I've been trying to hear the station for nearly 50 years.

Thus far all of the stations logged have been with a barefoot receiver. I have a feeling the time is near when I will modify a PL-380 to hear weaker signals.

Good DX.

Congratulations on logging 800 stations. It's not an easy goal to reach. Best wishes on reaching 900 soon.

Thanks Richard........but hey...you can't be too far behind?? Where are you sitting now???

Don't forget Folks...it was Richard who was the FIRST to hit 700....and he was the Inspiration I needed to pull up my socks and be the First to 800!!

It sure isn't getting any easier though......but I'll keep Dxing and picking away.....surely 900 won't be that hard!!?? Yeah Right!! HAHAHHAHA...

Most of my Catches were on a Barefoot ULR...with a few in the Unlimited Class....which makes my 800 Award an UNLIMITED AWARD. I believe ALL of Richard's catches are BAREFOOT!! Amazing!!

I'm sure it won't be long before Richard joins the 800 Club!!

Assuming the supplied ferrite-rod antenna is tuned by the radio, as with the other Tecsun DSP radios, you're definitely correct. The antenna shown in the photo has a built-in tuning capacitor which will appear in parallel with the one in the chip. You'd see good LW and maybe bottom-end MW reception, but the high end would most likely be beyond the chip's tuning range. You can use the wrong LC on the chip and still hear signals; wire is conductive and rf has to go somewhere -- but the antenna would not work as designed. Being significantly larger than the dinky antenna they supply, it might seem better, but it's not the way to go.

Hi Nick,
Thanks for the notice.
A new PL-360 has been ordered (by EMS shipment), and will presumably be one of the new ULR's covered in the upcoming 2010 Shootout. It seems doubtful that this model can compete with the PL-380's or PL-310's, but sometimes a full review of a new model is useful in convincing all of us to be thankful for what we already possess :-)

Unfortunately, I do _not_ believe in this construction:

http://i.ebayimg.com/20/!Bk)gSCgBmk~$(KGrHqEH-D8EtW,EFpJ5BLY7)vWIBQ~~_12.JPG

The coupling of the antenna plus ferrite rod would give a much better signal.

Re: Re-Chiped G8

Roy <roy.dyball@...>
 

I thought I would post a picture of the torch used to solder in the chip for those interested. It actually belongs to my ex wife who purchased it to do jewellery work from eBay in the UK it only cost $5.00 and is of remarkable quality. Unfortunately the eBay site no longer exists. All I have done is unscrewed the soldering tip and I am using the flame jet as a torch. The flame can be adjusted very low. The battery is just there for size relativity.

Re: Sony M37 Filter mod

I cut and pasted this from directions I sent another ULRer.
Assuming you have this filter (sorry for the helter-skelter appearance):
"Look at the pinout scheme at http://www.euroquartz.co.uk/pdf/ceramic-lts-450w.pdf
All the grounds are
soldered together to wire to place in the ground hole. The
other two are input/output. It makes no difference
which goes
to input or output but you can determine which is which
by the
above scheme.
On 50J, the stock filter, pinout:
The pins on the filter are left to right on the printed
side:
input,
ground, output."

Another chip tells the DSP chip what to do, and handles the user interface functions. Roy bypasses that one with his USB interface.  The control chip  could be replaced if you had the data to program a replacement. Swapping those little surface-mount chips is risky work and Roy deserves a lot of credit for pulling it off!

Roy has found a way to interface a PC to the radio, defeating the default parameters. It requires a little work on the circuit board, and the changes only remain in force until the radio is powered off. On the next power-up the defaults are re-loaded, and he has to re-instruct the DSP chip. He's offered to help anyone who cares to hack a radio, though.

Sony M37 Filter Mod help needed

coffee_experts
 

Ooops - I see that the 1st message was not posted -

A user in the group sent me a Sony M37V and a replacement filter touted in the photo gallery as a useful mod for the M37V

Sadly, there are 2 photos and no discussion.

The user has sent me his new filter and M37V with no actual instructions
other than the dis-assembly - which sadly is incomplete.

Anyone in the group done this mod?

Another question about this MOD - the replacement filter has way more pins than the stock one - any idea which pins are used?

for the ULR Log which were # 799, # 800 and # 801 Heard on ULTRALIGHT
RADIOS!! Number 799 was logged last night at Bedtime....and the other 2
bringing me over the 800 mark were logged tonight at SUNSET. Number 799
was a CALL CHANGE for the OVERALL LOG...and 800 and 801 are NEW to the
OVERALL LOG as well.

The trek to 800 ULR Stations heard began on JAN/01/2008.....making the
total time elapsed to hit 800 Stations on ULR ......2 Years and 33 Days.

Nice that # 800 was a LOW POWERED 500/57 Watts Station!!

I Logged # 700 on Oct/04/2009...so it took 2 days shy of 4 Months to get
the next 100 Stations.

It has been a lot of Fun and a lot of Work to get these last 100
Stations......but now it's done and I can move on to the next 100 New
Ones and # 900 somewhere down the road.

Radio Used for these Loggings is......SONY SRF-T615 ULR BAREFOOT
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

ULR LOG TOTALS are now......801 Stations heard
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Re: Re-Chiped G8

Hey... if it's possible to replace the chip in a G8.... I wonder if it might be possible to replace the chip in a PL-380 (or other radio with that chip) and completely defeat the soft mute (by getting a chip with different parameters programmed onto it), for example?

Re: PL-360

Pollock,Raphael E <rpollock@...>
 

Agreed, if it has any sort of a front end--if not I predict massive overloading. Now, if it is really a 380 that has merely been switched out horizontal to vertical that would really be exciting--I would love to direct couple my 27" Stormwise wound w/ 660 Litz to a 360 if it is a performer "as is"--particularly if it has switchable AM band witdth--is anything known about the chip inside the 360??

The fact that the AM antenna can be plugged in will make this radio a promising test bed for "bigger, badder" loopsticks.
