Re: Digital Readout SRF-59

Guy Atkins
 

Hi Rob,

Is a digital readout SRF-39 (clear-cased "prison" version of the SRF-59) close enough?  :^)

John Bryant accomplished this in 2008, as another one of his clever and top-notch radio projects. Here's the link to the DXer.ca download area where you can find an article about it:


John's widow Linda gave me this unique digital readout SRF-39 project along with a number of other items John built. I feel honored to have them, but I certainly feel a twinge of sadness every time I admire or use one of these creations John designed.

In his article, John described making a more permanent and attractive housing or case for the digital SRF-39. I hope to accomplish this some day in his memory. We worked on many radio modifications together over the years, often building upon and improving each other's ideas in rapid fashion.

I was just tuning around on this digital SRF-39 last night, amazed at the stable frequency readout down to 1/1oth of a Kilohertz! John built in a vernier gear reduction drive, too, so tuning is much easier than with the tiny thumbwheel in the stock radio. 

Right now I'm using the tiny stock ferrite antenna that was built into the SRF-39 originally, but John made provision for an inductively coupled external antenna. So, there are possibilities galore for antenna experimentation too.

Re: A Cold but Productive DX Commute - 3 New Beacons

Gary DeBock
 

Hello Kevin and All,

Thanks for your NDB-DXing report, Kevin. I was also up in the
subfreezing weather this morning chasing NDB's in the back yard, and
found the DX a lot hotter than the temperature. As you mentioned
233-ALJ at Johnstone Point, Alaska (Prince William Sound) was strong,
and I made a recording of it on the 7.5" LW loopstick PL-380:
http://www.mediafire.com/?b0l1y92wlhcygpz . Besides this, both Yukon
(248-QH) and NT (222-WY and 375-FS) were received for new provinces
here. NDB totals now on the LW plug-in loopstick PL-380 are 98
stations, 7 states (AK, WA, OR, CA, ID, MT and UT) and 6 provinces (YT,
NT, BC, AB, SK and MB).

For those interested in either LWBC or NDB-DXing (or both), Rob Ross
and I have already agreed to offer Ultralight Longwave-DXing awards as
soion as possible, which will be in exactly the same categories as the
MW-DXing awards (states, provinces, countries, hundreds of stations
heard, etc.). I think that Kevin and I both know how meaningful a 100
NDB Heard Award would be! Rob and I are discussing the final artwork
for the Longwave-DXing Award Certificates, which will be offered to
Ultralight DXers anywhere in the world. Get your loggings ready!

73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)

Hi all:

After taking yesterday off from morning DXing (dental appointment), I
was packed and ready to go last night, so I got to my picnic table in
the park this morning around 0530 local. It was COLD (at least for
here) - probably 28 degrees F.

Three new ones, including a new state/distance record, thanks to Gary's
tip:
233-ALJ Johnstone Point, Alaska (1305 miles)
248-QH Watson Lake, Yukon Territories (903 miles)
356-PND Portland, Oregon (140 miles)

The ULR log is now at 95 total.

Improvements to the DXing set-up included a cheap 12" plastic turntable
to rotate the radio/loopstick around (a HUGE improvement), putting my
station listings in a plastic sleeve protector, and an extra layer of
insulation to sit on. I still need another pair of socks and an extra
pants layer - after about 80 minutes in the cold, I was pretty chilled
through! I will probably start packing a pencil, since the pen was
writing sluggishly in the cold.

Rob - the local men in blue haven't spotted me yet (the park
technically isn't open until sunrise), nor has a Homeland Security
helicopter flown over trying to figure out what I'm doing with the
suspicious-looking long white cylinder :-)

Re: Comparing ferrite loopsticks a box loop on longwave

The PL-360 tunes some of my loop and long wire antennas, and still works with ones it cannot tune exactly. [It has a small ferrite you can unplug.]
All of my DSP radios can be coupled to an external ferrite or air core loop AM antenna too. - FARMERIK

This is a neat trick, allowing for enhanced sensitivity.
Not all Tecsuns, only the Tecsun receivers, and Grundig G8, using the Si4734 IC have this built-in varactor which is one of the best features of the chip. The inability to use an external MW antenna in a stock SI4734 based Tecsun or G8, PL-606 excepted, is a serious shortcoming. I've been able to tune a 24" square spiral loop, a 60 year old loop antenna from an old Zenith AM/FM radio, and several different ferrite bar antennas easily with my modified PL-380 and PL-310 using the internal varactor in the Si4734. As long as the impedance is within the chip's specs, the radio will tune it with no external capacitor needed.

Maybe Tecsun will start including the ability to use an external MW antenna in future radios like they have in the PL-606.

Re: An even More Monstrous ferrite on the way

Pollock,Raphael E <rpollock@...>
 

Hi Kevin!
 
The 48" 125 mu ferrite rod I purchased from Stormwise last year got to me without any warping, etc. I may try spreading out the coil on this one--perhaps experimenting with 28 AWG before committing precious Litz in a more finished product. I am not sure how much more Q I really need; the tuning right now, even with vernier reduction drives, is pretty sharp, especially above 1200 kHz--I am wondering if more Q would mean, in a practical sense, more functional gain which might be helpful (maybe?) in listening to low powered graveyard frequencies versus simply even more narrowed tuning...
 
I will await your results before doing any major surgery!

The guy at Stormwise did mention that the reason they only advertise up to 18 inch versions is that at some point he's concerned about them getting bent, either in shipping or in final use. With the PVC coating on them, and the inherent strength of the ferrite material, I am not too worried about it, though. It'll be here next week, so I will report back how it fares.

Anyway, the T615 fits almost perfectly. The case is designed for an iPod and includes an earbud extension that connects a jack on the outside of the case. This fits the T615 too. With the case closed the radio is very secure. There's a pocket in the lid that will hold the earbuds and extra batteries.

Hi Raph:



The 800 mu permeability is still fine for resonating on MW, as far as I can tell. I have been comparing the 800 mu stick to my Q Stick, and the signal gain is substantially leap better on the Monster. The guy at Stormwise mentioned that to get max Q for the upper part of the band, the windings should be spaced out along the ferrite as much as possible: I will likely convert the "little" 18-inch ferrite to MW-only, in which case I can do just that. Both of our MW coils are close-spaced, which minimizes the amount of Litz wire one needs, but apparently Q suffers. So, you might want to try spacing out the coils on yours, using a longer length of Litz?



I am thinking that if I were to take it on a trip and try to carry it onto a plane, I would bring a copy of the construction article to show them what it is. I would have it in a mailing tube, and I would go to the post office at the airport and mail it back to myself rather than have them confiscate it. If I were to check it in a bag, I might use a stand-alone shipping tube of some sort, perhaps one made for a fishing rod, again with a copy of the construction article in there should they decide to check it out. Using a hard-sided suitcase, with the antenna put in diagonally, might also work.

Hi all:
I just got off the phone with Stormwise, intending to order another 18" "Monster" ferrite, since I have a few other ideas about what to do with them. As it turns out, they are available in 2" increments, so I special-ordered a 24" inch model of the 800u permeability type (Model VFR24J). I think they're all made to order, so it's just a matter of him telling the fabricator how long to make it.
He wasn't exactly sure of the price, likely $10 or so more than the 18" (which runs $33.75), but he'll let me know as soon as he gets a firm price on it. So, in about a week I should have an even larger Monster ferrite on hand, which I will likely devote to longwave with regeneration.
Looks like I'm going to have to find a longer backpack for my morning commute DXpedition gear...

Good job with WKIP. There are a string of stations up/down the Hudson River, that were recently purchased. The old WCKL on 560 has been resurected and put back on the air. I believe these stations share some local commercials, so you might find WCKL again. I believe its on original power of 1000/43 Watts.

Had to lay out a 500 ft BOG to do it, but turns out it points at Venezuela also, and that has given me a few more using a (whisper) non-ULR mostly.

Re: An even More Monstrous ferrite on the way

The guy at Stormwise did mention that the reason they only advertise up to 18 inch versions is that at some point he's concerned about them getting bent, either in shipping or in final use. With the PVC coating on them, and the inherent strength of the ferrite material, I am not too worried about it, though. It'll be here next week, so I will report back how it fares.

I could be wrong here, but I was under the impression the Stormwise ferrite
rods were made of packed ferrite powder. This explains why they're available
in such a variety of lengths. I would think there to be very little danger
of breakage of the ferrite.

Hi Raph:

The 800 mu permeability is still fine for resonating on MW, as far as I can tell. I have been comparing the 800 mu stick to my Q Stick, and the signal gain is substantially leap better on the Monster. The guy at Stormwise mentioned that to get max Q for the upper part of the band, the windings should be spaced out along the ferrite as much as possible: I will likely convert the "little" 18-inch ferrite to MW-only, in which case I can do just that. Both of our MW coils are close-spaced, which minimizes the amount of Litz wire one needs, but apparently Q suffers. So, you might want to try spacing out the coils on yours, using a longer length of Litz?

I am thinking that if I were to take it on a trip and try to carry it onto a plane, I would bring a copy of the construction article to show them what it is. I would have it in a mailing tube, and I would go to the post office at the airport and mail it back to myself rather than have them confiscate it. If I were to check it in a bag, I might use a stand-alone shipping tube of some sort, perhaps one made for a fishing rod, again with a copy of the construction article in there should they decide to check it out. Using a hard-sided suitcase, with the antenna put in diagonally, might also work.

Hi Kevin!

Glad to see you becoming even more addicted to monster ferrites as well! I am wondering how well the 800 mu ferrites will work on MW as compared to the 125 mu--I don't know enough radio electronics to answer my own question. I also wonder about transporting the completed ferrite rod antennas. There is too much effort to make one of these things only to have it confiscated by Homeland Security at the airport, thinking that it might be a pipe bomb or some damn thing. On the other hand, I wouldn't want to take a chance of ferrite breakage by putting it in checked luggage...

Your thoughts, my friend?

Subject: [ultralightdx] An even More Monstrous ferrite on the way



Hi all:

I just got off the phone with Stormwise, intending to order another 18" "Monster" ferrite, since I have a few other ideas about what to do with them. As it turns out, they are available in 2" increments, so I special-ordered a 24" inch model of the 800u permeability type (Model VFR24J). I think they're all made to order, so it's just a matter of him telling the fabricator how long to make it.

He wasn't exactly sure of the price, likely $10 or so more than the 18" (which runs $33.75), but he'll let me know as soon as he gets a firm price on it. So, in about a week I should have an even larger Monster ferrite on hand, which I will likely devote to longwave with regeneration.

Looks like I'm going to have to find a longer backpack for my morning commute DXpedition gear...
