The minimalists' voice:
-----------------------
All tubes and parts over 50 yrs old. One stn had to be rcvd with 2.5 kHz
bandwidth because changing of frequency: one for dots and another for dashes
(SP6LV)
Had built a TX with 2N3553 for 40 and 20mtrs. So when I realized the QRP-MAS
was on 80m I was too late... (ON5JD)
Had a hard time, but none too hard. There was after all a 100% increase
compared to 2000, hi. It is difficult for a "northern light" running 0.25w
to get through to the "southern states". Mni stn hrd, no QRN(!) (DF2OK)
It is not easy to find the MAS-rules in the Internet...I've made this TX
especially for this contest and it was very pleasant to make some contacts
with other HAMs also making small transmitters (ON4ATZ)
Some time ago, I put together a frugal radio based on the Pixie
principle, just for fun ... on Ascension Day I happened to stumble
over the MAS rules in my inbox. So I dragged the thing from a corner ...
and got a big surprise when the answers came in ... (DL1SAN)
My first QRP-MAS. Can tune my rig from 3570-3580 kHz (VXO with TV-crystal)
...Scanned my 10 kHz one hour but nil...Tried a long CQ on 3575 and DJ1ZB
answered ..... there are few stations in the contest, I guess (OM3CUG)
7.5dB more power compared with 2002, but 2.4dB less QSOs. Paraphrasing
a famous cartoon inventor: "A little volt here, a little Ohm there, and
soon there'll be little oscillating symptoms!" (DK9KR)
All good things come in "threes". This was my third complete defeat
by QRN! Definitly my last stint at MAS under such conditions (HB9XY)
Gave up after 10 QSOs because of heavy QRN ... (DJ2GL)
Regrettably I lacked time to add coil and variable capacitor to my
tiny tx ... A suggestion: Please listen to the sides of your frequency
after a cq. Called stations only 2-3kHz off my frequency in vain. The
high QRN level didn't help either. It wasn't our lucky day! (DL1EH)
Alternate start in class B on short notice. After about 2100UTC
tremendous QRM ... almost nothing heard thereafter (DL1JGA)
With all these ionosperic handicaps bagging HB9XY after umpteen
futile attempts was almost like working ZL! (DJ6FO)
Some new call signs, others were missing. The QRN wasn't nice, but
bearable. Probably less so for QRPp stations (DJ1ZB)
At last also participants between 3540 & 3560kHz! Unfortunately my ant
is very noisy, resulting in poor s/n ratio and "thin" signals (DL1ARH)
A great challenge, a superb contest! Thanks to all stns (DL3LQM)
Enjoyed the Session but couldn't hear much in the QRN hash, sri (DL9QM)
My Hartley acted up, frequency stability unsatisfactory due to the
aerial swaying back and forth in the wind ... (DL2MPF)
Working conditions were difficult due to QSB and QRN (OZ9KC)
Completely new construction for MAS, VXO range 8kHz, 4kHz of which were
occupied by a jamming station. A jam session so to speak (DL1AZK)
A pity that conditions during the test were not optimal.
But still a nice contest (OZ9QM)
Less QRN than anticipated, but no connections to the north because
of Aurora (DJ9IE)
... wrote the log during MAS (it shows it, hi). Conds improved after main
TV time. Unfortunately most participants were in bed by then (OE8GBK)

------------
Thank you for participating in spite of bad condx, for your logs an comments.
Are we moving into tropical zones? For a second time many suffered from QRN,
which wasn't a problem for all. Or are we also a little spoiled by HiFi or FM
radio, and expect higher levels of comfort compared with times when a
summertime ionospere wasn't noticeable in our crystal sets headphones?
It probably is simply statistical hard luck, this increased QRN on Ascension
Day since 2000. In decades of FD participation (1st weekend in June) we
experienced serious QRN in much less then half the number of events.
Despite all this, participation in class A increased by 50%, keeping the
total at the same number. This indicates a grown potential of interest.
There was good activity at the "experimenters frequency" (3579 kHz minus
VXO-range) for the first time.
Often a few more dB and a QSO wouldn't have been hashed up. So maybe 15v at
the pa transistor's collector instead of just 12v, raising a Pixie's output
from 250 to 500mw? And a full-sized dipole instead of a G5RV.
Thus we gain 6db and complete QSOs.
So: "A QRPer never gives up"!
73/2 de "Hal", DJ7ST
