Hello Jim, and first of all thank you very much for your help. The Agilent was set for an amplitude of 50mVpp but I don't know if this setting applies to noise generation as well (I think I should st
Hi all, are you experiencing problems in sending e-mails with attachments to the reflector? In the last hour I have tried multiple times to send a message with about 400KB of JPEG's attached but it s
Hello Stefan, I'm about to complete the construction of an E-probe based on your design (the original one, with both BF862 on the same board). The resulting PCB size is not that small as I preferred
Hello LF, VLF, I don't want to annoy you with my homebrewing stories and questions, however I would greatly appreciate any comment/advice on the following. I have just completed construction of a BBB
Hello Alan, LF, VLF, thank you very much for your suggestions about how to perform more sensible measurements. The Agilent 33120A is a general-purpose function generator. Among other functions, it is
Hello Stefan, if weather allows I will try to receive your tx. Good chance for a comparison between different antennas at my QTH (I hope I will have three ready for test by saturday :-)). Regards D.
Congratulations Chris, this is really a great result for you and Stefan :-) Cheers D. From: Chris Gomoiu <[email protected]> To: [email protected] Sent: Sat, December 4, 2010 2:37:21 PM
Positive (but noisy) reception of 8970 in JN53EM with the easyloop, despite of high QRM. Background noise has decreased slightly only during the final part of Stefan's tx. Nothing on E-probes and at
Hello Ken, as far as I know, the 2SK170V could be a good candidate. Best regards Daniele From: Ken <[email protected]> To: [email protected] Sent: Wed, December 29, 2010 5:58:31
Hello Ken, I bought the BF862's at RS Italy. The sell them in 10x strips. May be you could try and see if RS UK have the same policy. Best regards Daniele From: Ken <[email protected]> To:
I agree. Also consider that even a negative result is a progress, compared to no results. So good luck and best 73's Daniele From: Rik Strobbe <[email protected]> To: "rsgb_lf_group@blacksh
Hi LF, very interesting info. However, often the line input of a sound card is used to connect a pre-amp (rather than the mic input which is more prone to overload). Am I wrong? Best regards Daniele
Hello LF/VLF, in your opinion, could it be possible (i.e. sensible) to "couple" somehow the coax feed of both the PA0RDT Mini-Whip (R) and a VLF E-probe, as roughly depicted in the attached figure? T
If weather assist, may be next sunday morning I will be trying a broadband recording (up to 24KHz) in /p from hills behind my QTH. My Zoom H1 recorder with its standard SD memory only has room for ab
Currently my SpecLab window covers from 8969.95 to 8970.05 (so 8970Hz +- 50mHz) with 141uHz FFT and 10 minutes waterfall scroll interval. Initially I started with 3mHz FFT and 60 seconds per scroll (
