Stefan, Congratulations and best wishes for great RX! If I can be of any help regarding practical solar charger system design (optimizing overall system cost, performance and reliability) in your (li
Graham and Tobias, Thanks for all of the information, I'm looking forward to implementing the options that you mentioned. 73, Jim AA5BW Thanks for the run down Tobias The windows re-sampling caused p
Paul, Good info and results! LWPC is acknowledged as having a rather poor terminator model; no suggested workaround that I know of, other than customized LWPC or other customized EIW modeler. Do you
Paul, I wish that was my signal but unfortunately I'm not on the air. Thank you for your previous feedback; I am working to add 10dB - 15dB TX power per your suggestion. I see (here in northern Virgi
Paul, I've been monitoring near 8820 since Dex's prior transmission (assessing and mitigating noise in case Dex switches on again). I don't have good absolute-frequency calibration at this northern V
Paul and Dex, Thanks for great data. The phase data is interesting as always; especially since models still lag empirical data. In the absence of accurate analytical modeling tools for VLF propagatio
Nice work Dex and Paul! 73, Jim AA5BW --Original Message-- From: [email protected] [mailto:[email protected]] On Behalf Of Paul Nicholson Sent: Thursday, December 18
Does this mean that ERP is now well above 150uW? 73, Jim AA5BW --Original Message-- From: [email protected] [mailto:[email protected]] On Behalf Of hvanesce@comcast.
Stunning. Great work Paul and Dex! Fine noise management too; 11dB @ 0.12fT and 278 uHz implies approximately 2fT/root-Hz aggregate noise? Jim AA5BW Last night was the best reception of W4DEX so far
Paul, Impressive (low) system noise and agreement of Example 6 model with results. 73, Jim AA5BW aggregate noise? That's about right for a quiet night. That's after sferic blanking - before the blank
Paul, Congratulations to you, Dex and the rest of the team on this work, including 73% channel capacity in the midst of many constraints! I had planned to ask if you thought that any atmospheric phas
Paul, Thank you! I'm always looking forward to higher SNRs that could enable applications of the types that you mentioned below. The rarity (that you so aptly described) of useable (calibrated or val
Paul and Markus, That's inspiring especially in a watt-for-watt or pound-for-pound context, with respect to some legacy systems. At roughly 1E6 pounds for an OMEGA transmitter/antenna-system with pre
Hello Stefan, I was not monitoring this morning so I did not see the signal tuning between 13 kHz - 14 kHz but I will look for it in the future. During the past two weeks I have noticed a signal tuni
Paul, Ref: " I can easily see 10uW from 1000km in one hour over a path with a lot of land. West to east over water will be lower loss and four or six hours integration will make up for the lower ERP.
