Re: 7.5” Loopstick LW antenna not enough inductance?

Thanks Steve,

This must be why my 12" Longwave FSL wound with 1162/46 Litz wire was able to track down four new South Pacific NDB's at the Rockwork cliff this month (320-AI, 346-TG, 352-RG and 366-PNI) that I never could get with the 660/44 Litz wire :-)

Re: 7.5” Loopstick LW antenna

Hello Igvitk (and Steve),

<<<  I’m trying to make the 7.5” loopstick LW antenna according to the instructions. I used the Amidon R33-050-750 rod, 100/44 litz wire, made 122 turns of the coil, which is located exactly in the center of the rod and which length is 106,5 mm. However, the output inductance measured by the multimeter is only 1432 uh instead of 1700 uh. The similar result was shown by another multimeter VICY DM4070. I think that is a strong deviation. Can anybody explain how to solve this problem?   >>>

As Steve has explained, the specified 1700 uH is not an essential inductance value, and there are variations in the inductance of ferrite rods and Liz wire, even among the same manufacturer. The important thing is to have enough inductance to make your loopstick provide good sensitivity on your chosen Longwave frequencies, and in order to do this you need a lot more inductance than what SiLabs recommends for Medium Wave (180-450 uH). Your 1432 uH inductance should be fine for most of the Longwave frequencies, unless you wish to concentrate on chasing the LWBC stations from Europe and Africa on the lower edge of the band, in which case you may wish to add a few more coil turns to raise the inductance up a little. For NDB chasing you should already be OK with the 1432 uH.

Originally five test models were made up for the Longwave loopstick design project, and they were all compared on different Longwave frequencies using a Tecsun PL-360 plug-in system. Full details are contained in the article posted at  http://www.mediafire.com/file/845snah2h4ek9z9/7.5inLWLS.doc/file

Curious, I unsoldered my R33 LF coil and measured it--1546 uH at 100 kHz test frequency--so mine isn't close to 1700 uH either, yet mine will tune down to at least 200 kHz with my PL 380 ULR. Here in USA there are no LWBC stations to be heard so I try for NDBs, which only go down as far as 198 kHz (DIW in North Carolina, a powerful NDB).

So I guess your R33 rod has even less permeability than mine, and the 1432 uH is probably correct. If you can rewind it with more turns, that's what I'd suggest doing. It wouldn't matter if turns on the end were under the rod support, that wouldn't affect the rod's pickup.

Re: 7.5” Loopstick LW antenna low inductance problem

Steve Ratzlaff
 

Assuming you're using a real R33 rod, which if you bought it from Amidon, is most likely the case, then it sounds like maybe your rod's permeability is lower than other R33 rods, and that other than rewinding and putting on more turns, you're stuck with this inductance. I realize the rods are very expensive ($20 here in the USA, plus shipping) so you probably wouldn't buy another one just to see if it gives more inductance. Depending on how low you want to tune in LF you may be able to get by with this lower inductance rod and coil. So you may want to just put it on the radio and see how low your particular radio's SiLab's IC tuning will go--maybe you'll get lucky and it will tune low enough.

Thanks Art (and Paul),

We would be honored to have you (and/ or Dave) to join us in one of our Rockwork "Cliffhanger DXing" sessions someday!

As for choosing DXing priorities, we all face tough decisions. At the Rockwork cliff there was exceptional Longwave NDB-DX (from Australia and New Zealand) coming in at the same time as exceptional Medium Wave DX, which for a live Ultralight radio DXer is probably the ultimate tough choice. Since the Longwave DX was much more rare I went after stations like 320-AI (Aitutaki, Cook Islands), 346-TG (Tauranga, NZ) and 366-PNI (Pohnpei, FSM) when I could have been chasing rare Kiwis and Aussies on MW. But my partner Tom Rothlisberger was recording it all on his Perseus-SDR, so not all is lost :-) He made out like a bandit!

Gary, you remind me why I moved here :)
One of these days I need to get Dave and I to join you up there.
Still unpacking, repairing and refurbing..... more than once on some things.
My two big MW loops need to be repaired.
My HF Ham activities (what time I have) has definitely shown a flare for liking Trans-Pacific/Equator. I get rare islands and Asia on 14 MHz fairly easy when the antenna is working (had to repair again yesterday). 
Europe is a struggle due to my location against a hill. 
It is also a little noisy, but will work with that.
I am spending time getting adjusted to what nearby AMBC powerhouses are around here.
Do I Ham, do I MW DX, do I FMBC DX ...... ???? Do I put up my tower?  .... decisions decisions.   I also love the Wine country :)

At the risk of receiving some rotten tomatoes across the border from Victoria I decided to compile a detailed report of the final Rockwork Cliff DXing session on August 9th, mainly because there is far more time for such activities back at home. The DU's are somewhat more enhanced at the ocean cliff site, especially for blasters like 531, 558, 603, 1017 and a few others. Nick has spent some serious time at the Cliff himself, so he knows the score.

This last session was a wild one featuring enhanced DU's on both Longwave and Medium Wave at the same time (1230-1300), making it tricky to choose priorities in live DXing. At my 1200 setup time there was no South Pacific NDB propagation on Longwave, but a spot check at 1230 revealed 260-NF on Australia's Norfolk Island at a fair to good level, and the Longwave NDB rush was on. A detailed search was made for trans-equatorial beacons, and although propagation wasn't quite up to Thursday's standard, the final tally wasn't bad for a hot-rodded Ultralight--  238-KT (New Zealand), 260-NF (Norfolk Island), 320-AI (Aitutaki, Cook Islands) and 352-RG (Rarotonga, Cook Islands). 320-AI had apparently repaired its sick-sounding transmitter within a day, although its signal strength was down quite a bit from Thursday. During this Longwave search 531 kHz, 558 kHz and 1107 kHz were being recorded on dedicated Medium wave FSL's, and both 531 and 558 kHz caught some of the Longwave enhancement effect, resulting in S9 signals (and ID's) from both 531-More FM and 558-Radio Fiji One. 603-Waatea also pounded in at S9+, although that was after the live DXing switch back to MW around 1300.

Biggest impression of the morning (except for the unusually smooth ocean) was the potent boost that the enhanced Longwave propagation seem to provide for both 531-PI and 531-More FM, who seemed to tap into some extra strength from 1245-1315. Unfortunately, with the overwhelming strength of both 531-More FM and 558-Fiji there was no chance to check for Western Australian parallels on 531 and 558 to match the ABC football game heard on 702 kHz. The Longwave NDB's provided another thrilling session, though, with multiple low power stations crossing the Equator at great range.

Rockwork Cliff (Oregon State) Ultralight South Pacific DX for 8-9 (Final Session)

Gary DeBock
 

At the risk of receiving some rotten tomatoes across the border from Victoria I decided to compile a detailed report of the final Rockwork Cliff DXing session on August 9th, mainly because there is far more time for such activities back at home. The DU's are somewhat more enhanced at the ocean cliff site, especially for blasters like 531, 558, 603, 1017 and a few others. Nick has spent some serious time at the Cliff himself, so he knows the score.

This last session was a wild one featuring enhanced DU's on both Longwave and Medium Wave at the same time (1230-1300), making it tricky to choose priorities in live DXing. At my 1200 setup time there was no South Pacific NDB propagation on Longwave, but a spot check at 1230 revealed 260-NF on Australia's Norfolk Island at a fair to good level, and the Longwave NDB rush was on. A detailed search was made for trans-equatorial beacons, and although propagation wasn't quite up to Thursday's standard, the final tally wasn't bad for a hot-rodded Ultralight--  238-KT (New Zealand), 260-NF (Norfolk Island), 320-AI (Aitutaki, Cook Islands) and 352-RG (Rarotonga, Cook Islands). 320-AI had apparently repaired its sick-sounding transmitter within a day, although its signal strength was down quite a bit from Thursday. During this Longwave search 531 kHz, 558 kHz and 1107 kHz were being recorded on dedicated Medium wave FSL's, and both 531 and 558 kHz caught some of the Longwave enhancement effect, resulting in S9 signals (and ID's) from both 531-More FM and 558-Radio Fiji One. 603-Waatea also pounded in at S9+, although that was after the live DXing switch back to MW around 1300.

Biggest impression of the morning (except for the unusually smooth ocean) was the potent boost that the enhanced Longwave propagation seem to provide for both 531-PI and 531-More FM, who seemed to tap into some extra strength from 1245-1315. Unfortunately, with the overwhelming strength of both 531-More FM and 558-Fiji there was no chance to check for Western Australian parallels on 531 and 558 to match the ABC football game heard on 702 kHz. The Longwave NDB's provided another thrilling session, though, with multiple low power stations crossing the Equator at great range.

Another great report as always Gary. It is great to read about how well some of our stations are making it across to your side of the world.

Starting with the extremely rare appearance of the 500 watt Longwave NDB 260-NF (Norfolk Island) on an Ultralight radio it was an Oz-slanted session on the cliff, as several Australian stations temporarily took over Kiwi frequencies on the low band. This caused some interesting frequency fights, such as on 603 where the unusual 4CH came in at a very good level at 1305, only to be completely buried by an S9+ Radio Waatea a half minute later.

The morning session started off with a bang as I set up the  Ultralight Longwave gear for the second day in a row, hoping to simply check some of the Alaskan NDB's along with Tom. The Hawaiian super beacon 353-LLD was unusually strong, though, so on the outside chance that one of the super rare South Pacific NDB's might show up I checked for 260-NF on Norfolk Island, a 500 watt beacon off the coast of Australia.  At 1205 I was stunned to find NF already pretty strong with a decent signal, the strongest I had ever heard it. After notifying Tom I went back to the gear and tried for 270-FA (MIA), 238-KT (a 2 kW beacon at the northern tip of NZ, received at a fair level), and 352-RG (MIA). In the predawn darkness I tried to find a list of more target frequencies, but the Longwave propagation to the South Pacific tanked around 1220 on the Ultralights.

The Australian stations made their big move after 1300, and were dominant by 1330. The identity of 639-2HC around 1320 was easy to determine now that 639-RNZ has shut down, since a single commercial ad rules out the ABC stations. David Sharp's 585-2WEB showed up at a fair to good level with rock music around 1329, with the first 2WEB ID I've ever been able to decipher (barely) at 1330. I've received the station many times previously, but Programming Director David (a member of our Ultralight Radio group) always assisted me with the identity check by matching my recorded song with the station's music log. The first time this happened was in 2010 in Seaside, when I received an UnID rock station on 585 and railed on the Ultralight list about the "dumb Australian station on 585 that never ID's." Within a day I had an e-QSL from David, who had matched my recorded song to his music log :-)

Re: Wanted: Digitech ar1780 original

Mark Roberts
 

Correct, the XHDATA D-808 uses a rechargeable lithium ion battery while the AR-1780 uses 4 AA batteries. The AR-1780 supposedly can charge batteries but requires a very strange input voltage: 7 volts. The display backlight on the XHDATA is bluish-white; for the AR-1780, amber. The AR-1780 has just slightly richer sound and buttons that stand out a little more from the case compared to the XHDATA. As for performance, they seem to be identical.

Sorry for the delay in sending out your portable FSL antenna. One of the participants in the November Hawaii DXpedition had to cancel out for health reasons, so I'll be sending you the top-of-the-line Baby FSL that was prepared for him (once I get back home to Washington state).
