Roman, I don't know... The reflector has a size limit for attachments, about 40kB I think, but I don't know if this limit is the actual file size or the size of the file when encoded (with "base64"
Laurie, Yes, at least on Perseus. It has a dedicated "AGC OFF" button. Perseus uses the computer's default soundcard only for audio output (for listening). High speed USB 2.0 is used to transfer the
Perseus is a nice receiver. Except for the preselection filters and a little amplifier chip, just before the ADC, it is DSP all the way (direct sampling at 80MS/s) and it has an AGC OFF button! http:
Hello Rik, MMANA works very well for free space models but since it is based on MiniNEC, it does not properly model how the "real world" ground interacts with the near field. As far as I know, it use
Alberto, Yes. I'd suggest that you put that suggestion on the Perseus list to remind Nico that this question should have higher priority than the colour of buttons :-). I mentioned this VAC stuff to
Dear Jim, LF group, yes, all Wolf GUI settings were left at "factory default" except the speed which was changed to Wolf 20. Your signal was strong, clearly visible in the waterfall (well, with some
Jim, you seem to be running QRO ;-) I downloaded and fired up DL4YHF's Wolf GUI (of which I have no previous experience), selected the "20" mode, tuned the RX to 503.000kHz USB and in the next few se
Graham, please set the drive to give -6dB per tone (relative to max output). Since the signals are not exactly harmonically related, their voltages will add "in phase" every now and then and you will
Hello, it looks like K1JT is now joining the HF QRSS gang: http://physics.princeton.edu/pulsar/K1JT/MEPT_Announcement.TXT I doubt MEPT_JT will beat Wolf but it is definately easier to tune! 73 Johan
Indeed. The selectivity, and hence the QRM rejecting performance, of most e-mail receivers can be greatly improved simply by inserting a narrow filter in the signal path. With careful adjustment, the
I meant "rejectivity" and "narrow notch filter" of course... The selectivity, and hence the QRM rejecting performance, of most e-mail receivers can be greatly improved simply by inserting a narrow fi
Hi Solid aural copy of G3LDO (normal CW) and GI4DPE (QRSS3) in JO67MR. You are both around -115dBm +/-QSB on a horizontal dipole cut for 80m... PNG image
LFers, the usual design equations for class E amplifiers assume that the DC feeding choke has a very large inductance in order to keep the DC current practically constant over the RF cycle. I am in t
Tnx Gary, when Andy wrote "501.5kHz carrier" I thought he meant transmitted carrier on 501.5, not RX zero beat at 501.5... Stupid me... OOOPS! I just received a frame from Graham! C:\NonInstProg\MEPT
