  It is with great sadness that I have this news to forward to the Group.

  Dear John, dear lowfers,
  we are very sorrow to record, that the member of our hf-committee,
  Peter.W.Bobek, DJ8WL, passed away on april 26 by a malignant illness.
  He was born on july 25 in 1943. He became member of the hf-committee
  in 1992, was on the 160m toplist at 1st position all the time with 268
  countries confirmed. When we started experimenting on lf, he became a
  real pioneer on that new experimental area. We are missing him very
  much, he was a keen and very experienced ham, a  modest fellow and a
  really good friend.

• Subj: 136 kHz
  Date: 99-04-28 10:49:59 EDT
  From: DragoJug guestarnessi (Drago)
  Hello,
  In Slovenia (S5) amateurs have had about 1 Year VLF band 136 khz (june 1998). First QSO (S55WT and Club station (op S51XK) S53DTB) within first Minute when the Band was open. This is only QSO in S5.
  S53DTB building now the receiving antena and TX (RX is TS870).
  And limitations: we have 1 W ERP !

• Subj: New UK station on 259Khz
  Date: 99-04-28 04:33:10 EDT
  From: MMuehlba ELSAde (Michael Muehlbauer)
  Hello All,
  It was reported Sunday April 25th on Radio Caroline that a new station was licensed in the UK to operate on 259 Khz, just above Atlantic 252. The station's construction was reported to be in progress and would begin operation in the later half of 1999. No other details were given. (strange freq. selection for the European LWBCB)
  I will try to get more information and post it as it becomes available.
  Additionally, if you are interested in information on Radio Caroline's new service to Europe (currently broadcasting on weekends) have a look at the following address: http://members.tripod.com/seek67/index.htm for frequency information, MP3s of broadcasts, and links.
  Thanks,

• Subj: TUK returns
  Date: 4/21/99 12:04:15 PM EDT
  From: WilliamAshlock edwardsboc (Ashlock,William)
  I was pleased when I checked out 194 kHz last night and found TUK back on the air. I was never able to determine why they were not transmitting. The total off-time was approximately 30 days. Anyone know why?

• Subj: Rcvrs on LF
  Date: 99-04-16 22:03:51 EDT
  From: sratzlaf flash (Steve Ratzlaff)
  Hello.
  I use an AR-7030 and it works very well to 10kHz. I don't know about hearing whistlers with it, though. Several very active NDB DXers use the Drake R8 versions with good success on LF. A friend with an NRD535D uses it for all his LF listening, down to at least 18.2kHz (18.2kHz, VTX3, the Indian station, widely heard all over the world). The much older Icom R70 tuned down low with decent sensitivity. One DXer in San Diego uses that as his primary LF receiver.

• Subj: receiver query
  Date: 99-04-15 12:44:39 EDT
  From: n7ue (David B Ritchie)
  I am intereted in getting into VLF -- how do receivers such as the Rockwell HF2050 and the Collins R389 stack up in this game? What does one look for in a good receiver (apart from a good antenna!)
  Thanks

• Subj: R8B vs AOR 7030 on LF?
  Date: 99-04-14 11:00:02 EDT
  From: n3ikq juno (Richard M Jones Jr)
  Hi,
  Have any of you had the opportunity to compare the performance of the Drake R8B and/or the AOR 7030 below 500kHz? I read one review of the 7030 where the user was able to tune below 10kHz to hear whistlers etc.
  As a Ham I wish someone would make a transceiver that is not crippled below 160 meters. I heard the TS 850 did well but have not heard of any newer rigs (sub $2000) doing well down there. I can say that the receiver in the IC-706 (original) is not good at any frequency and is horrible at LF. It does hear its own CPU/display pretty well down there though! Any thoughts will be assimilated into my decision making process.

• Subj: BK frequency 184.700
  Date: 99-04-09 18:09:17 EDT
  From: bhkoehler mmm
  For about two weeks now, I have been running BK on 184.700 KHz alternating BPSK/CW. I moved the frequency to get away from computer birdies at LEK's location.
  I heard QYV again fairly well a couple of weekends ago. I'm still hearing LEK, RM, SAM and BRO regularly and LEK, BRO and BK sometimes exchange BPSK messages at MS25 ET1 on weekends.

• Subj: Switched Capacitor Filters
  Date: 99-04-07 14:26:18 EDT
  From: WilliamAshlock edwardsboc (Ashlock,William)
  I am working on narrowband filters for Lowfer use and just came across a series of switched capacitor filters from Linear Technology. They have a LTC1064 series of quad switched capacitor filters and the AP notes contain a number of 8-pole Bessel/linear phase designs which show promise for this application. Additionally, I downloaded their Filtercad software and find it very useful in simulating different configurations. The Windows based program actually plots the amplitude, phase, and group delay Vs frequency, as well as the impulse response. The full schematic is also displayed complete with all component values.
  Has anyone out there experimented with these filters?

• Subj: First SM/SM QSO! (?)
  Date: 99-04-07 17:15:11 EDT
  From: sm6lkmjbeab swipnetse (Johan Bodin)
  I just had my very first two-way LF QSO. What a thrill! (my hands are still shaking...)
  I was experimenting with a rotatable shorted turn in my loading coil. I increased the supply voltage to my small PIC controlled beacon TX until I got 300 mA antenna current. Output power was about 4 watts. The PIC was sending "hello de sm6lkm" repeatedly in swedish (hello = hej). I remember thinking "no one can ever hear this tiny signal" when SM6PXJ phoned me from about 120 km away, telling me "hello, your have a good signal here!"... What a surprise!
  We decided to try a QSO and I did some soldering to get the straight key connected to the TX. When I called "SM6PXJ de SM6LKM K" Christer answered immediately.
  This QSO was made with normal speed CW and my PA is made of two small TO-92 transistors (BC337 / BC327) running on 27V.
  I think this we made the first two-way LF QSO within SM?
  I also heard G3KEV calling CQ at 19:00 UTC. He had a VERY good signal, "armchair copy" with SSB filter! Strongest G signal I've heard so far...

• Subj: European 137 kHz Activity on Website
  Date: 99-04-05 22:25:40 EDT
  From: bicking mwci (rbicking)
  There is a really useful website called DX Summit which features near real-time postings of activity on all the ham bands worldwide (I even saw my call appear there one morning reported by a ham in Sweden that heard me). It has 137 kHz activity reported on it (scroll down to "Custom Spots, 137 kHz").
  It is at: http://oh2aq.kolumbus.com/dxs

  "D" is still operating. AND I am retiring in June! and should have more time to pursue VLF!!!

  From: rikstrobbe fyskuleuvenacbe (Rik Strobbe)
  I just visited the Longwave Home Page at the new URL. It seems a go a lot faster than before, so it has been worth the effort.
  Some news about the 136kHz scene in Europe :
  - there is some activity in Denmark, I have heard OZ1KMR and OZ5N so far
  - 136kHz is released in Sweden by 1 April (no joke), but no SM's heard yet
  - in Italy IK1ODO got some companions in the '5' call-area (I5MXX, IK5ZPV heard)
  - YO2IS seems to have a 136kHz permit and is trying to get QRV

  To: webmaster lwca.org
  Hi John. Just a short visit on the first of April to see your new page. Nice indeed. Seems there are so many more items of interest than before along with a few newer contributors. We must make an intense effort to include the AMRAD people. They seem to have the ARRL ear as well as the Europeans, especially so with PSK31 efforts.
