Pete, This is the phase noise of the 930's LO, plus the amplified noise figure of the transmitter stages all the way back to the carrier generator. Because it goes out through the Tx LPF you will fin
Hi Denis, Glad you found a good seat for the 7QP. We didn't get the 2el 80m up at WS7N last week. will have to wait. He did get the 160V up so look for N7LE from Deschutes County on all bands. All th
The title in the last 7QP thread is confusing. The 7QP starts 1300 UTC Saturday May 6 and runs 18 hours to 0700 UTC Sunday. That is 6 AM to midnight PDT the first Saturday in May. There is now 7QP su
I built a multiplier file for TR that will let me log and properly parse all the possible exchanges for NEQP, 7QP, and IN. I'll generate a Cabrillo file at the end of the weekend for my 7QP entry, th
If you send in an electronic log, we will score it regardless of extraneous contacts. The 7QP organization has a very competent IT department. It is our intent to make this as easy on everybody as po
Mr. Marconi would not have used "IE" or any other of those "ditty" American Morse characters. Rather, he would have used the "Continental Code". It was developed over "on the continent" (Europe) ca.
Steve, Just making a heavier coil will not cut it. The fundamental limitation is the RF current carrying ability of the mica caps. These are what fail even at 100W. The filters could be modified for
This coming weekend is the FQP, one of the QSO Party "biggies", and the Nebraska party. The following weekend is another "biggie" -- the Indiana, New England and 7th Area QSO parties. If you are not
The results for the second running of the 7th Area QSO Party are posted on the www.codxc.org web site. Certificates and plaques will be sent out the Tuesday after Field Day. We thank all who particip
The new CO QSO Party debuts this weekend on Sunday, after the IARU. If you all have any strength left after the IARU, come out and join us. Keep an ear out for K4XU/0. My wife has (more or less) volu
Whoa Scotty, WiMax is not BPL. It's a VHF/UHF wireless service, one of the possible denizens of the "UHF TV channels" the be vacated in 2009 when DTV becomes the law of the land. Dick Date: Fri, 19 O
Tony, Find yourself a 24V filament transformer with a current rating equal to the amp's AC draw. Hook it up as a boost auto-transformer. We did this in Europe when the SB220's would not make rated ou
We interrupt this protracted yet scintillating discussion of SKIMMER to bring you the following bulletin: 7QP is this weekend starting at 13Z May 3 and ending 07Z May 4. There are three or five other
This has nothing to do with driving at 4AM or Sprint. I just rejuvenated an old hard drive and found .25M of old contest logs, all in CT's .bin format. Some of these go back to 1992. There are CT7, 8
I tried to play in all three state QP's but was frustrated by VA's requirement for a SN. I got N1MM to accept all the different county exchanges by modifying the QSOParty.sec file. But when I worked
Dick, The largest Tokyo Hy-Power amp at 1500W output, uses two ARF1500s in push-pull at 100V. These are very large 500V MOSFETs, easily capable of 750W output. I quite am familiar with the devices in
For those of you who like more than one week's notice of upcoming events, the fifth 7QP will be May 2nd, the same weekend as the NEQP and Indiana QP. W7 stations are reminded that they can work India
The triple play QSO Party is next weekend, May 2/3. 15 states at once! Warm up this weekend in FQP and NQP. It was suggested that mobiles stay above 14.045 and fixed stations stay below 045. That way
This is a reminder to all procrastinators -- the log submission deadline is Tuesday, 5 June. We will take any log as long as it's in a clear text format, and paper logs <40 QSOs. You need not separat
Ten more days to get your 7QP log into 7qplogs@codxc.org Log submissions are way ahead of 2009 partly due to N1MM's ability to run the NEQP, InQP and 7QP at the same time in one log. (Thanks to smart
