Other than a few very limited openings, late February and
March, reception of North American 50 Mc amateur transmissions in
Europe finished in mid-February. This more or less followed the
pattern of the previous season. This article comprises a review
of the six-meter scene on this side of the pond, and of the
1957-58 DX season.
During November and December of 1957 reception of W and VE
stations on 50 Mc was an almost daily occurrence here in England.
It is fantastic to compare this with the state of affairs four
years ago, when 14 Mc was indifferent and a W QSO on 21 Mc quite
a rarity! Such is the influence of the sun-spot cycle.
Not being licensed until 1949, and then only using QRP, the
writer, G3FXB, barely tasted DX working on 28 Mc during the last
cycle, and so, with increasing sun-spot counts and rising MUFs,
operation during 1954, 1955 and 1956 was centered on 21 Mc and 28
Mc.
Reading about the F2 openings on 50 Mc that occurred in 1947
prompted interest in that band and in December of 1956 the
writer's first cross-band QSO was effected with W1FOS. W1GKE,
W1HOY, W8CMS and others followed. The band seemed good in 1956
but pressure of business precluded any serious work and it was
disappointing to note the collapse of the band in January, 1957.
The last 50 Mc signals actually heard being on January 8th, 1957,
when W4s and a Channel 2 video carrier were audible. However,
openings commenced again on October 27, 1957 and it was obvious
that the winter of 1957/58 was going to see 50 Mc hotter than a
fire-cracker.
Getting equipped for listening on 50 Mc in England is no problem.
A very nice item of war surplus known as the RF-26 unit is a
ready made six-meter converter. It may not have the most
wonderful of noise factors but it sells brand new for the
equivalent of about four USA dollars. For the record, it tunes
from 50 mc to 65 mc and employs the output frequency of 7.5 me.
The RF and mixer tubes are somewhat similar to the 6AK5 and the
unit uses a separate triode oscillator. In England, 50 Mc is slap
bang in our TV, Channel 2 - so, if a fellow is in a Channel 2
area, the domestic receiver antenna can be tuned W-wise and put
to good use! This of course providing the QRM from video is not
too bad. TV in England is vertically polarized and whilst the
writer used the domestic 2-element TV antenna in 1956 it was
decided to use a horizontal antenna for 1957 with a view to
reducing the video QRM. The local TV Channel 2 station is but
four miles away and unfortunately openings on six meters in
variably coincide with test patterns which spread a generous 2.5
Mc of video all over the band.
During November 1957 a crude 3-element wire beam was used at
G3FXB but tests indicated that the driven element of the G4ZU
tri-bander beam was giving one s-unit better saying a lot for the
efficiency of the wire beam. The driven element of the G4ZU beam
is 24 feet long and at a height of 25 feet is centre fed with 450
ohm open wire line. Time did not permit the erection of anything
better and the incentive of transmission in G-land has been
largely nonexistent. In early November, 1957, my local
collaborator in the world of DX began to show an interest in six
meters, Stan G2DPY. In fact, his XYL bought him a RF-26 unit for
his birthday present. If ever an XYL regretted a birthday present
- this was it! Stan became an ardent six-meter man and being a
shift worker was in a position to give the band a fair bit of
attention. Acknowledgments are due to Stan for much of the
information in this write-up, also to short-wave listener John
Whitington of Worthing who also procured an RF-26 unit and
promptly started to log the six-meter boys. John used just one
leg of a 21 Mc dipole whilst Stan started with a 3-element indoor
wire beam and later increased this to a 6-element wire beam
similarly situated.
On the whole, the east coast boys were the most co-operative in
listening on ten meters but plenty of the lads down south and out
west could have made any number of contacts cross-band six to ten
meters, had they listened on ten. For our part, a mid-west or
west coast QSO was for obvious reasons, of greater interest and
to hear fellows such as W5PDE, W7ACD, W7JRG at S9 calling
"CQ Six" was a most frustrating experience. One knew
that no matter how hard one called, there was not a hope of
raising them! There were days when west coast and mid-west
signals were the only ones audible on six meters - no east coast
at all! When these western gentlemen came in they came in with a
bang. The strongest signals I have heard on six has been from
stations like W5PDE, W5SFW, W5VY, W7ACD, W7JRG and W9DSP.
Some days the band shut at dusk, other days it did not open until
dusk whilst often it stayed open a couple of hours after
nightfall. Earliest reception of six meter was recorded at 1215
GMT - W1GKE and the latest at 1800 GMT - W8CMS.
Just before Christmas the GPO (British licensing authority)
announced the granting of special limited permits for
transmission on 52.5 Mc. Unfortunately in all but a few remote
areas, operation was restricted to non TV hours - 0001 - 0930
GMT. With 50 Mc slap in the TV band such restrictions were hardly
surprising. It was immediately suggested to the authorities that
another normally non-TV period 1300-1400 GMT might be made
available as trans-Atlantic contacts seemed completely ruled out
during the 0001-0930 period.
Permission was not granted and thus no operation on the 52.5 Mc
band was entertained. The return for the effort involved seemed
rather negligible. MP4BBL (Bahrain) and ZC41P (Cyprus) might well
have provided cross-band QSOs but that seemed about the only
possibility in the 0001 0930 period. Incidentally, both these
fellows were fully prepared for six to ten cross-band with W and
VE but they did not hear any signals. They have both made regular
cross-band contacts with VQ2, ZE and ZS via trans-equatorial
scatter. When six was open things were hectic and it must not be
forgotten that quite often the problem was TV video QRM.
Unfortunately the beam bearing for the USA coincided with that
for the local TV channel! "CQ Cross Band Six-meters"
has been good fun. Lets hope that by the time this appears
in print we shall have enjoyed some fall openings on six meters.
As a follow-on to this article Herb W3IWU has supplied his log
and comments relating to openings covering the same time period,
1957/58. In those days Herb was licensed as W5LIU in Lubbock,
Texas (DM93 by today's rules). I was very active during the above
period, in fact I never forgave Al for not hearing me! I worked a
fair share of the DX, and must have called CQ a million times,
but I did not appear in his article! I would call your attention
to the many reports of W5, 6 and 7. Cycles 21 and 22 certainly
did not match up from that standpoint.

I never realised how fragmentary these notes were. But 36
years makes some of the recollections QSB! At the time I was
freshly out of the Army, married a little over a year, had a
young child, was going to college full time and was working full
time. Six Meters was a STRONG magnet though!
Just for the record let me mention that there were several
stations (beacons if you will) which were put on air in about
1958 for propagation purposes. CE8AE in Antofagasta, Chile,
several KW, large rhombic aimed NW and a pair of Yagis to the
East on 49.96MHz. OA3AAE in Arequipa, Peru, high power, rhombic
NW on 49.92MHz. OA3AAF in Huancayo, Peru, low power, 49.88MHz.
These stations began operating on 15th Nov. 1957 and transmitted
continuously with CW IDs on the hour and half hour. There was
another station, KK2XFS referred to as Mapleleaf (Canada) on
49.28MHz,
