-
- How about a missed first?
-
- I had not done _any_ overseas hf (having just done vhf/uhf
- and Field Day U.S. hf contacts). So, one weekend I actually
- put up what I thought would be a decent antenna (a borrowed
- vertical I wanted to compare to my then nearly worthless
- wire antenna). I started tuning around in the Novice 10M
- voice band and started hearing DX! Ok, now _everybody_ has
- worked 100's of JA's, but _I_ had NOT.
-
- So, I start dropping in my call in response to the QRZ. It
- wasn't a busy day or anything, but there were plenty of folks
- who wanted to chat with the JA for a couple of minutes or so.
- I tried this for about 30 minutes, but the JA never came back
- to me. By now I'm wondering if my SB1400 has suddenly become
- rx only! Why wasn't I getting a contact?
-
- About this time my wife (Amateur Extra-KI5EV, Dawn) comes in.
- When I explain my frustration she says "Let me try it!". Well,
- I figured she could get frustrated to match me, so I got up and
- gave her the microphone. At first QRZ she joins the frey: "This
- is Kilo India 5 Echo Victor". Boy, I thought, with that normal
- voice and using long phonetics she'll _never_ get through: must
- have been twenty other calls while she said all that!
-
- The JA came back up as the chatter of responses died: "KI5EV,
- go ahead, where are you located?". I darn near flipped out!
- So my wife chats nicely for a couple of minutes, logs the QSO
- and hands me the mic as she gets up. As she's leaving she
- brightly observes that she doesn't think there's anything wrong
- with the radio. Thinking that I could kill her later, I just
- jumped back into throwing N5RCK into the QRZ pile.
-
- Needless to say, that session died as the freq went south and I
- had to say sayanara to any hope of a JA contact that day.
-
- Oh yes, I did get my first JA (and so first DX) the next day.

- Subject: GB2RS News 22nd May 1994
- To: info-hams@ucsd.edu
-
- Good morning. It's Sunday the 22nd of May and here is the GB2RS news
- broadcast, prepared by the Radio Society of Great Britain.
-
-
- And we start this week's broadcast with the good news that at a recent
- meeting with the RSGB the Radiocommunications Agency (the RA) assured
- the Society that the amateur radio licence fees would not be increased
- during the next year. The last increase was made in April 1991.
-
- Not such good news is that the Radiocommunications Agency has
- experienced a number of problems in recent months with unattended
- operation of amateur stations, and have asked us to publicise the
- following:
-
- Quote:"ATV stations operating in the 1.3GHz band have been left running
- unattended on sites remote from the main station address, and have
- caused severe interference at distances of 30 - 40km away to air traffic
- control radars which are the primary users of this band. The Amateur
- Licence does not permit unattended operation of TV in this band (except
- where a Notice of Variation has been issued for a repeater, and these
- are subject to careful site clearance procedures). Operation outside of
- the terms of a licence is unlicensed use, and enforcement action (which
- could mean prosecution and/or revocation) can be expected in these
- cases. This is particularly so where a safety of life service, the
- security of which is the RIS's first priority, is at risk." End
- Quote.
-
- The potential consequences of being unable to close down an unattended
- transmitter that is causing interference to such services are very
- serious. It is important that all amateurs behave in a responsible
- manner and adhere to the procedures in the licence for unattended
- operation.
-
- The RA have also had to investigate interference from unattended
- operation of digital modes on 144/432MHz. The licence does not require
- notification to the local Radio Investigation Service (the RIS) for such
- operation under clause 2(4)c, but amateurs should perhaps give some
- thought as to how their station could be closed down in their absence if
- problems arise. It might be wise to inform the local RIS of such
- operation as a precaution. These matters are currently under discussion
- between the RSGB and the RA.
-
- One of the many Special Event Stations commemorating the forthcoming
- anniversary of D-Day is already in operation. This is GB0FYO, which
- remembers the visit to Portland by King George the 6th and Sir Winston
- Churchill on the 25th of May 1944, in preparation for D-Day. This
- station is operated by the Portland Amateur Club from the Portland
- Heights Hotel. A comprehensive list of special stations will appear in
- June's Radio Communication.
-
- The HF Committee of the RSGB has a vacancy for a keen HF DXer. The
- committee, which is responsible to RSGB Council for all HF matters,
- meets approximately every two months in the London area. If you feel you
- can help, write, with brief details of any relevant experience, to the
- committee chairman, David Evans, G3OUF, P O Box 599, Hemel Hempstead,
- Herts, postcode HP3 0SR.
-
- The June issue of Radio Communication will be posted out to members
- during the week commencing 23rd May.
-
- A DXpedition to the Shiant Isles, which is south-east of the Isle of
- Lewis, is scheduled to take place from next Friday the 27th until Monday
- the 30th of May. The team comprises: GM3NIG, GM3UTQ, GM4FDM and GM4YMA.
- Operation will be on all bands 160 to 10m, mainly around IOTA and WAB
- frequencies using the callsign GB8SH. The primary mode will be SSB, but
- CW, AMTOR, Pactor and RTTY will be available on request. Shiant is IOTA
- EU 112 and WAB NG49.
-
- We now give further items of HF DX news taken from the weekly RSGB DX
- News Sheet which is edited by Brendan McCartney, G4DYO.

- Hi Susan, I've been a ham for over 40 years and my Elmer told me back
- in the early '50s that the term originated with English hams. The
- English term for ham originated long before amateur radio and was
- generally applied to a person who was an amateur at anything, e.g.
- ham actors. In my opinion, it probably originated in antiquity as

-
- Hmmm, I've seen this too (the power save/no receive problem). I wonder if this
- has anything to do with the recent sale they had on the HTX-202 (quite a
- significant price cut). If this is a valid bug, will Radio Shack do anything
- to repair? PS- I thought I was doing something wrong, until I read all these
- notes & that prompted my interest. I was using the power save along with the
- tone-receive squelch for the Central Texas net, which uses PL tone. When the
- power saver was turned off, I was able to receive QSOs in progress.
- Also, you can only change frequencies during the time slice when the radio
- wakes up. In other words, there is no keyboard or control knob interrupt to
- wake up the sleeping radio.(other than turning off sleep, thank goodness)

- I do agree that VHF/UHF is a good way to get on the air and make friends.
- But the same can also be true on HF. I've been addicted to contesting and
- DXing for many years. I've made tens of thousands of quick signal report
- contacts on HF. I have made many friends in the local area who have the
- same interest. The friendships often go way beyond just a mutual interest
- in ham radio. Also made many friends all over the country (and world
- to a lesser extent) that share the same interests. If I am traveling
- around the country these ops generally will take me out to dinner, show
- me the town, etc and often offer me a place to stay.
-
- In 1984 I had a quickie contest QSO with a station in Guyana. I sent for
- a QSL card and also asked about getting a license to operate in Guyana (it
- was very hard to get on from 8R at that time). I ended up visiting Guyana
- that year during the CQWW SSB DX Contest. This gentleman found me a house
- to rent where I could put up antennas, helped me through a pile of red tape
- to get a license and get my equipment through customs (took four days). He
- met my plane and returned me to the airport and invited me over for several
- meals with his family. The first weekend I was there the Boy Scouts were
- having their ham radio weekend. I helped the scouts get a station set up,
- designed and installed the antennas and got the kids on the air. Granted
- this is an extreme case, but all this resulted from one 15 second contest
- QSO with a gentleman who believed in the fraternal aspect of ham radio.
-
- By all means get on VHF/UHF and enjoy but don't forget about HF. After all
- the years I've been on the air I still get a kick just from just making
- contacts around the country or around the world (whether they are short
- or long contacts). Despite all the negative things presented here in this

- be had.

- higher latitudes. The solar flux levels saw a very welcome and steady
- increase from 77 units up to 91 units. There were a number of small B
- type flares reported on the 11th and 12th, the largest being a B9.
-
- The sunspot indices averaged 44 but rose from only 12 on the 10th up to
- 77 by the 15th, the highest level for 2 months. Solar flux levels also
- rose from 77 units on the 9th, up to 91 units by the 15th, giving an
- average of 85 units for the period. The 90 day mean solar flux level was
- 87 units on the 15th. The geomagnetic activity has been up to storm
- levels at high latitudes most of the period; this was due to the passage
- of coronal holes, causing very high levels of electron fluence. The only
- quiet day was the 13th when the Ap indices was only 6 units. The period
- averaged an Ap index of 22.5 units. The state has been 'mag storm' most
- of the week. The aa indices as supplied by the British Geological Survey
- for the 3rd to 9th May gave an average of the daily index as 54.2
- nanoTeslas, about K4 though periods on the 5th, 6th, and 7th, were up to
- 102 nanoTeslas about K5. The monthly average aa index for April was 40.2
- nanoTeslas, the only quiet days were the 28th and 30th down to only 4
- nanoTeslas, and the most disturbed was the 17th up to 97 nanoTeslas.
-
- The X-Ray flux levels have shot up, possibly due to the flare activity
- and reach A9.4 units on the 12th, the highest level since last March,
- with the period averaging A7.1 units. It seems likely that the recent
- restructuring of the sun's surface is now settling down and more stable
- conditions will result.
-
- I'll repeat the figures. Spots - 44; Flux - 85; Ap index - 22.5; X-ray
- flux - A7.1.
-
- Now the ionospheric data for Central France:
-
- The F2 daytime critical frequencies at Poitiers as reported by Meudon
- averaged 7.1MHz, though levels rose from 6.2MHz on the 10th up to 7.9MHz
- by the 15th, with peak levels being around 19.00 hours most days. The
- darkness hour lows have also risen, from 2.6MHz on the 10th up to 4.6MHz
- by the 15th, with the average being 3.4MHz centred about 04.00 hours.
- This is more like the levels we would expect due to the seasonal changes
- taking effect.
-
- I'll repeat the figures. Highs - 7.1MHz; lows - 3.4MHz.
-
- Now the ionospheric data for the north:
-
- The F2 daytime critical frequencies at Ekaterinberg have been very
- depressed due to the magnetic storms, with the daylight averages being
- only 5.6MHz. The darkness hour lows averaged 2.8MHz.
-
- News has been received that on the 1st and 2nd May during the aurora,
- W2CAP/1 and W3 stations heard TV stations on 49.72MHz, on the great
- circle bearing, believed to be by auroral E shortly after midnight until
- 0240 hours.
-
- I'll repeat the figures: Highs - 5.6MHz; lows - 2.8MHz.
-
- And lastly the solar forecast:
-
- This week the more active side of the sun will be coming into view.
- Solar flux levels are expected to be about the 80s, and geomagnetic
- activity is expected to be quiet at first, increasing to disturbed by
- the end of the week. Ionospheric levels during daylight are expected to
- have MUFs up to 24MHz in the south and 21MHz in the north. East/west
- contacts will be difficult, though sporadic E may assist. The darkness
- hour lows are expected to be up to about 14MHz in the south and 10MHz
- for the north.
-
- And that is the end of the solar information.
-
- Finally in the main news, SSL has informed the Society that as of last
- Wednesday morning, the latest callsigns issued were in the G0 Uniform
- Whiskey and G7 Sierra Juliet series, and Novice calls in the 2 0 Alpha
- India and 2 1 Delta Alpha series. .
