New email address and new MedFER antenna
Posted by Doug Allen on July 02, 2003 at 18:05:14
Hi guys and gals,
Left you all in February when I was overwhelmed with other things. Last August, I started with a part 15 compliant Medfer beacon on about 1695.7. The tophat was about 56 SF at a height of about 12'. Although it was easily heard on groundwave at 30 miles, I took it down in September when my LowFER beacon went on the air. To my knowledge, no one tried to hear the MedFER beacon while it was on the air, though I had requests to listen AFTER I replaced it with the LowFER beacon. Sooo, this season I'll put the Medfer beacon on starting in mid-July with a much larger (153 SF) tophat at 15' using the more liberal definition of part 15 antenna restrictions. The redesigned LowFER beacon will be placed in service in September. Maybe I can be heard this season by some of the 1500 mile+ LowFERS I copied last season? And I hope you will listen for my Medfer beacon when I announce it is on the air.
Cheers,
Doug W0AH

Not clear what that "more liberal definition" of Part 15 is, Doug. Are you talking about a 15-foot tall antenna? That wouldn't be compliant with anything I've ever seen in print from the FCC.

Posted by Doug Allen W0AH on July 04, 2003 at 15:18:53
Yep, John Davis is right. I was thinking 15'...but after looking at the Part 15 FCC regulations I see it's the 15 meter antenna length for LowFER antennas that was in my foggy brain! So back to 10', but with the much bigger top hat. I had modified the top loaded vertical to 21'for Field Day. It worked pretty well with a little base loading on 75/80 at our Field day GOTA station. An A/B test this morning shows it to be about 2 S-units down on 75 meters from my 50'Hytower. I'll reduce its height and resonate it on 1695 KHz today with the same home brew coil I used last year. Tomorrow I'll rebuild the little 2N2222 oscillator I had on the air last September. Doug W0AM DM78lx
Product Review in July Lowdown
Posted by Robert Bicking, W9RB on July 03, 2003 at 15:28:59
Just received my copy of the subject Lowdown today and was very interested in the product review on the G0MRF LF Xmtr kit as I have also built one. I originally was planning to operate on both 136 kHz and 160 kHz so modified the low pass filter. With the FCC nixing the 160 kHz allocation, I scratched that idea and completed the xmtr before the recent elimination of any hope for a LF band in the US. It works fine into a dummy load but it would be nice to hook it up to my LowFER antenna and see if I could actually have a QSO. Would have been even better to be part of exploring this portion of the spectrum with more than a watt. I built the 400W version which uses two torroidal cores. Anyway, looks like a nice radio with nowhere to go.

Longwave DX Europe to New Zealand
Posted by Mike Terry on July 09, 2003 at 15:50:33
Interesting comment on HCDX about Longwave DX Europe to New Zealand - Mike)
"Hi,
I just read in our newspaper that the Czech longwave transmitter Topolná on 270 kHz can be heard in New Zealand. Not too much technically written article does not say anything more so I wonder if anybody living in New Zealand or Australia ever heard this transmitter from the middle of Europe or any other european LW transmitter?
In fact it could be possible as this band is clear in southern hemisphere and powers of EUR transmitters are high.
Several years ago a power of Topolná has been reduced from 1500 to 650 kW.
Thanks for your kind info,
GOOD DX,

Re: VLF Low Data Rate
Posted by Dave Rickett on July 10, 2003 at 19:28:42
Glad to hear there is some interest. Sorry for the delay but I've been away for a couple of weeks.
The ERP will be small no matter what I do but I'm using solid and multi-turn 3/4 inch copper water tubing in 6 to 8 foot diameter sections and impedance matched for 2/4 Ohm audioamplifiers feeding several hundred to 1000 W. I've reviewed formulas to estimate the actual radiated power but the numbers are so low it depresses me to calculate them. The favorable signal to noise variable is long time period dsp of at least 10 seconds or 250000 24bit samples or more likely 2 minute(2500000 samples) or 2 hour sample analysis lengths. This requires a lot of computer performance and memory but I think it's worth a try. The other factor is the requirement for very stable and precise frequencies of say 8999.999. There is a signal generator based on WWVB that would more then do the job but currently I'm limited to 1 part in 100000 using an old Globlal Specialties digital signal generator. Software I've found are limited but have tried 2500000 samples at 24 bit depth. I'm looking for commercial or semi-commercial(share ware) that will work on my G3 Mac with 700 MB ram.
I'm located in So. California(USA) and am staying below 9kHz to avoid our FCC frequency allocations but not lower to get more ERP. Military interference wasn't a consideration.
Best regards,
Dave Rickett

LF RADIO-DATA:
SPECIFICATION OF BBC PHASE-MODULATED TRANSMISSIONS ON LONG-WAVE
D.T. Wright, C. Eng., M.I. E. E.
Summary The BBC long-wave a.m. transmitter network carries a low bit-rate data signal, in addition to the normal programme signal modulation. The data signal is conveyed by phase-modulation of the carrier, the signal parameters being chosen so that there is no disturbance to reception on existing domestic receivers. This Report describes the data signal and includes details of both the data signal message structure and the modulation parameters.

I have since been told that probably the BBC still do phase modulate the longwave transmitter. That's presumably why it can't be tuned in properly on sidebands. Apparently the data is to control things like electricity meters.

Re: UK - BBC phase-modulated transmissions on Longwave
Posted by Jacques d'Avignon on July 17, 2003 at 07:07:23
The signals piggy backed on the BBC signals are indeed to control the electriciry meters. If you are a subsciber to this service,you get a lower rate for your electricity, I believe, after midnight, and the low rate is in effect untill 4 or 5 in the morning. So you do you heavy use of electicity at that time: dishwashing, ironing, clothes drying etc.
Very interesting system.

Low Data Rate DSP
Posted by Dave Rickett on July 17, 2003 at 15:05:16
A VLF source is ready and measures up to 40 Amp-turns in 6 foot and 7 foot diameter loops. Its based on a 400 W linear audio amplifier. The frequency is 8999.99 Hz for 2 minutes on and 2 minutes off then repeated.
What time should it be running? Continual is too much ac power consumption. Any suggestion for operating time by someone who wants to try and detect the signal is welcome.
I'm currently asking the half dozen or so Mac spectrum analyzer software developers to make their products usable for 2,500,000 to 25,000,000 sample FFT analysis or unlimited. Does anyone know if there are PC software spectrum analyzers that can handle that many or unlimited FFT sample size? The best Mac software for this purpose I've found is Amadeus ll. Its spectrum display uses up to 260,000 FFT sample analysis at 24 bit sample depth and displays a resolution of 0.1 Hz.

Re: Low Data Rate DSP
Posted by Alan G3NYK on July 17, 2003 at 18:28:06
Sound interesting Dave, but are you not going to be totally submerged in the 150 harmonic of 60Hz?? I currently run Alberto's Spectran (on a PC) which has a resolution of 0.021Hz when sampling at about 5kHz. Averaging and integration is available. Before you waste too much electricity I would see whether you can detect it about a half to 1 mile away. Small loops are very inefficient at these frequencies. Best results so far seem to be with "ground-dipoles". I will be interested to hear the results.

Re: Low Data Rate DSP
Posted by Alan G3NYK on July 17, 2003 at 18:32:27
Hi Dave.... Brain out of gear at this end.... you will need to sample at 18KHz at least of course. Spectran gives 0.084Hz resolution with a sample rate of 22kHz.
Cheers Alan
Re: Low Data Rate DSP
Posted by Lyle Koehler on July 17, 2003 at 22:34:30
Someone will have to check my calculations because the results seem a bit pessimistic even to me. Here are the numbers:
Radiation resistance of a 1-turn loop with a diameter of 2 meters at 9 kHz = 2.49 E-13 ohms.
Effective Radiated Power (ERP) with 40 ampere turns = 3.98 E-10 watts in free space, but if the radiation is confined to one hemisphere, it will be twice that or about 8 E-10 watts.
From a very old copy of Reference Data for Radio Engineers, the daytime atmospheric noise in a 10 kHz bandwidth centered at 10 kHz is roughly 1 millivolt per meter. The corresponding power density is E^2/377 or 2.65 E-9 watts per square meter. If we assume that the effective bandwidth of the spectrum analyzer software is 0.01 Hz, the atmospheric noise power density in that bandwidth is approximately 2.65 E-15 watts per square meter.
In the far field (beyond a few km), the power density from the transmitter is the ERP divided by 4 * PI * R^2. I already took account of the fact that the radiation is confined to one hemisphere in calculating the ERP.
Starting with an ERP of 8 E-10 watts and a noise power density of 2.65 E-15 watts per square meter, the signal and noise would be equal when 4 * PI * R^2 is approximately 300,000. This yields a range of 155 meters. We didn't make it into the far field, so the calculation is incorrect, but the implications are not encouraging. To get out to 5 km, the bandwidth needs to be reduced by a factor of about 1000, to 0.00001 Hz. Unfortunately it would take over a day to detect the signal, and since the atmospheric noise level is significantly higher at night, it is probably best to shut down at sunset and pick up where you left off in the morning for a few days.
Maybe I screwed up the calculations, but Alan is correct in stating that small loops are not very efficient at these frequencies!

Hifer PBJ back up now
Posted by Chris Waldrup on July 19, 2003 at 12:23:37
I just put Hifer PBJ back up on the air. I have been using used gel cell batteries for the power source since the beginning, but went this morning and purchased a brand new 7.5 Ah gel cell from Batreries Plus. I hope to get beter results with this, as the used batteries have been only reading about 10.8 to 11 volts with my DMM after leaving them on the trickle charger for a few days. As always, reception reports would be greatly appreciated. And I am thinking of trying an experiment in a few weeks with another dipole that is 90 degrees to the one currently in use, so that others that have not been able to get the beacon may be able to.
Medfer PBJ should be on as soon as I can get its battery charged. I use a 14 Ah gel for it and I didn't want to buy one of those this morning when I saw how much they go for!!

Re: Status of Rugby
Posted by Alan G3NYK on July 21, 2003 at 18:05:44
Hi, I can't speak for the other two but Rugby 16kHz, GBR, and several other frequencies are definitely off-air and being dismantled. I have some "bits" of GBR scavenged from the skip, after out visit last month. Also one of our party carried away a valve for his collection. The only transmission from Rugby now is the 60kHz MSF transmission (for the radio clocks, and frequency standard) This is supposed to be under contract to BT until 2007.
The submarine service is being supplied by Skelton and Anthorn, which are run by VT-Merlin (who operate the BBC's transmitters) on about 19kHz. I dont know the exact frequency but I believe Anthorn was on 19.2kHz

Re: Low Data Rate DSP
Posted by Dave Rickett on July 22, 2003 at 22:57:47
These small estimates of ERP are why I don't calculate them. It might make me lose confidence.
But look how close this might be to working. 40 amp-turns is a snap and 400 amp-turns is doable by someone who is motivated.
0.01 Hz resolution is only 100 seconds of samples or 2,200,000 sample FFT's. "Frequency" analysis software is being currently modified to use millions of FFT sample sets. So I'm speculating that my old G3 Mac will get to 0.001 Hz. And what about Apple's new G5 with 10 GB of ram? Will that computer go to 0.0001 or maybe 0.00001 Hz?
Do you get the idea that I think a <9kHz signal can work?

You don't need such big FFTs. If you low pass and decimate, you can have very small bin sizes with much shorter FFT lenghts.

VLF Low Data Rate DSP Noise
Posted by Dave Rickett on July 23, 2003 at 18:37:51
What is the noise at 8999.999 Hz? Lyle's earlier post on ERP raises an interesting question. He speculates that there is a noise level of 1 mV/m for 10 kHz bandpass at 10 kHz and a signal needs to be equal to the noise level to be detected.
How does the noise from 25,000,000 sample FFT's of 20 minutes signals compare to to the next 20 minutes? If those frequency analyses are similar then a signal much less than the magnitude of the noise is seeable on a sonogram style dsp visual presentation.
I'm looking forward to getting baseline noise data when my spectrum analysis software is squared away.

The oscillator should be buildable with common devices, if possible without coil manufacteuring, but it would be OK, if common solid inductivities, which look like resistors can be used.
If possible the oscillator should be AM-modulatable and working on voltages between 4 Volts and 16Volts.

https://gullfoss2.fcc.gov/prod/oet/cf/els/index.cfm and select "Call Sign Search," you can enter Laurence's call letters (WD2XDW) or mine (WD2XES)and see all of the applications and supporting documentation. Of course, mine hasn't been granted, so it may not be worthy of imitation!
Other call signs to check would be WC2XTC (Mike, W2AG), and WC2XSR (600 Meter Research Group).
