Hi Mal, You are even audible now here in JO21QV, albeit very, very faint... Sorry, as you know I cant TX yet.. -- Ceterum censeo Carthaginem delendam esse From: [email protected] mal hamilton Sen
.. And he is even visible on my grabber! I raised the miniwhip from +4 to +11 meters (large fishing rod in the backyard). Signal levels increased by 15 dB. Noise level was raised too, but the QRM fro

Hi Wolf, I just started up my main machine and the mail. Now the mysterious messaged on Speclabs screen start to make sense J (curious how you do this, additional string in the http request I presume
Oke, Ive changed the scrolling speed from (the default) 1485 ms to 700 ms per step. Lets see how that works out. 73s Minto pa3bca -- Ceterum censeo Carthaginem delendam esse From: [email protected]
Mal, I agree (seeing that Jan PA3ABK can hear you loud and clear). I currenlty use a PA0RDT miniwhip in the backyard, about 4 meters above the ground. Certainly not optimal, must improve.... I am doi
Hi Stefan, See attached screenshot just dug it up from my saved screenshots. As you can see you were significantly stronger than PA0A more than 5 dB.. nice! (time shown is in CET) 73s Minto pa3bca --

Hi Stefan, Well my praise for your signal strength certainly was not meant to imply a derogatory comment on PA0A Your sig was just very strong. As it is now, clearly audible. Regular CW would be no p
Hi Roger, nothing on my grabber (http://pa3bca.pa3bca.nl:8181 ) I changed Speclab to 84 mHz, scroll speed 5sec/dot. (note: my freq scale is a bit off and will drift overnight, due to air cooled 10 MH

Hi Gary, Thanks for the response. Well I heard Opera signals here tonight on 501.80, 502.00 and 502.20. You may check the Delft websdr (I am using this websdr at the moment as my RX ant is not back u
I am not convinced that this Opera beaconing (experiment??) is a good thing, that is to say not as it is currently conducted on 500. For some reason the frequencies that are used are smack in the mid
Hi Graham, It is possible to use the parallel port of a PC to control the DDS, the DDS has a 3-wire SPI interface. See for instance: http://www.qsl.net/p/pa3ckr//signalgenerator/ . Here you will find
Ah now I see where the confusion comes from. The page youre referring to contains an on-line calculator for the DDS (Device Configuration Assistant). Here you can for instance calculate the frequency
Or, as long as you are going to use a PIC anyway, order a AD9850 DDS module from buyincoins.com. This 0-40MHz DDS costs less than $5 (including shipping). Add a cheap PIC, a $5 2x16 LCD and a rotary
Graham, Did you find a website of the mfg of this specific board? I cant find it, although there is plenty of info on the Internet for this specific board (pin layout, programming specs). And of cour
Hi Roman. My current TX produces 100 Watts, and the calculated efficiency of the antenna is abt 0.6%: 0.255 Ohm radiation resistance calculated with MMANA-GAL and a measured total antenna system impe
Yes I am curious too.. I already found out that an FSK shift of 0.1746 Hz instead of 0.1831 (-4.6%) poses no problem. Also my AD9850 DDS board will creep between 0,5 and 1 Hz during a 15 minute TX pe
