W8JI: I'm not sure that is a good way to get a multiplier or QSO. I've been operating CQ WW 160m CW since 1972 when YU got permission. Located in downtown S5 capital Ljubljana with HV transformer sta
DL5MAE: A very nice summary of the new digital EME era you find at: www.blog.sm2cew.com Chat-room was new technology for me in the recent CQ WW 160m CW contest. Net gain - one mult! EME program writt
N4ZR quote: However, it strikes me as absurd to combine packet (one-way data, information only) and two-way liaison via Internet under the same category. W2EV quote from VHFcontesting: Ultimately, te
W5OV: Active Use / Passive Use. Very easy to understand and solves the problem. This statement reminds me of another famous Texan who said - You are either with us or against! I am sure USA lawyers w
K5TR: How do you think it would go if you showed them a radio but then called someone up on your cell phone to get someone on the radio so you could make a demonstration contact. George, some 20 year
Pete, PDF link is broken. All other articles show up as html. I wonder how contest community looks at future use of Skimmer for band scaning? I thoroughly enjoyed testing it on GJ/G3TXF UP1 pile-up i
N2IC: Before you outlaw computer assistance, consider another example of computer assistance - Pressing the F1 key to CQ on one band while listening on another band. You would have a heck of a time d
W4PA: If you decide to use a top-shelf HF rig for decoding CW signals, likely you're going to need more bandwidth than 3 kHz for watching signals up and down the band -- goodbye narrow roofing filter
G4BUO: The only contests that will be immune from the influence of Skimmer are the sprints - already a supreme test of CW skills. This might be the killer application for 48 kHz CW Skimmer - instead
CT1BOH: Very few people (less than 2% of the 2006 CQWW CW) have the physical, mental and concentration skills to do it. Jose, could you support this claim with some (in-house) medical data? I am awar
SO6R can be easily done with present digital technology sampling 30 MHz with 16 bits. Six DDS/NCO IC could be used to generate 6 separate data streams for each band. SDRIQ works on single channel wit
W4ZE: I use a 250 Hz filter for RTTY. I also use my 250 Hz CW filter in RTTY LSB on FT-1000. Many people operate AFSK with 3 kHz SSB filter. RX AGC reacts to the peak of strongest signal in bandwidth
Bruce, first thanks for your great hamradio work over the years. EU is small continent with 3 time zones but strong nationalism :-) There is a difference between propagation especially on the North.
N4ZR: It is likely, based on CPU loading considerations, that a real reverse beacon capability worldwide will depend on development of a web server capable of handling multiple simultaneous user requ
KR2Q: It would appear (unknown to me factually) that the ARRL policy is an attempt to short-circuit those QSL managers who can't resist sending out a QSL for a "one-off" callsign, in an attempt to ma
K6KR: I am not a hardware engineer, nor do I play one on TV... I like this statement from Hollywood land :-) Radio PTT is often pulled to +14V, data lines mainly to +5V TTL level. 73 de Mario, S56A,
N4ZR: In "spot everything mode, it reports every station it hears - you can imagine how useful this would be for a DXpedition station managing a big pileup. There are two potential problems: wrong ca
AB7E: My thought was that Skimmer could be written to capture the grid square of ALL of the stations it heard if that were part of the report. Small step is required on behalf of hamradio community i
K8FC: Effective S&P methods deem that you cover the band in a linear fashion as to not miss the possible mults. Linear search is not very effective but we were forced to do it before DX Cluster and S
W4PA: All I have to do is operate the run radio and point and click on the callsigns the Skimmer decodes for me. YM Scott & CT Jose, I am looking forward that you do that asap instead of being SO2R z
