Folks,
A good friend who is involved in VHF/UHF weak-signal work, forwarded
this to me, and I pass it on for anyone else who may be interested. Joe
Taylor K1JT, the author of the original message, wrote the WSJT
application which is used extensively in weak-signal work.

Subject: [HSMS/JT] Transceiver Clinic at the 11th International
EMEConference
Dear EME and VHF/UHF Friends,
As you probably know, the 11th International EME Conference will be held
on August 6-8, 2004, at The College of New Jersey. The Conference is
open to all radio amateurs interested in EME and other weak signal
communication at VHF, UHF, and microwave frequencies.
A special feature at this year's conference will be a "Transceiver
Clinic." Leif Asbrink, SM5BSZ, will run a number of commercial radios
through a battery of tests designed to establish their strengths and
weaknesses. Transmitter tests will include spectral purity under
constant carrier, hand-keyed CW, and normal voice SSB operation;
receiver tests will include noise figure, dynamic range, and reciprocal
mixing characteristics. Tests will be made using Linrad (Leif's
extremely capable software defined radio) as a high dynamic range
spectrum analyzer, as well as conventional signal generators, spectrum
analyzers, etc.
Find out how well your radio stacks up against others! Learn which ones
are unusually susceptible to QRM from nearby strong signals when
receiving, or may produce strong out-of-channel interference to others
when transmitting.
There will also be opportunities to sit down and play with Linrad as an
on-the-air receiver. Linrad is an extremely powerful tool for many
communication tasks, and especially for EME.
If you bring a radio to be tested, we will need:
1. The radio and an operator who is familiar with it.
2. DC power cord, if required.
3. The microphone that came with the radio.
4. Optional: connector or cable for the ALC port and the User Manual.
A 13.8 V DC power supply and dummy load will be available. It will be
helpful if you let us know in advance what radio(s) you will bring for
testing.
Details on the EME Conference, including registration forms, can be
found at

Feel free to pass this message on to other interested amateurs or to
post it on other reflectors.
-- 73, Joe, K1JT
