Paul, One approach Ive been considering is using an Arduino to generate DFCW. The book Arduino Projects for Amateur Radio has several related projects (CW Keyer, frequency generators, etc.) that coul
Hi Paul, Thanks for the info regarding your measurements. I believe you use a ScopeMatch in the shack to make your tuning adjustments and voltage/current measurements. I also run a ScopeMatch on LF a
Rob / Joe Any chance you guys could cozy up within a couple Hz of each other when running EbNaut? Jay W1VD -- Original Message -- From: Rob Renoud <[email protected]> Reply-To: <rsgb_lf_group@bl
LF EbNaut Enthusiasts, The K3RWR EbNaut beacon is currently transmitting on 2200m and will remain on the air through the weekend until Monday @ 1200 UTC 2018/11/1 (weather permitting) Operating Detai
Jay, Thanks for the reports! Based on your decode I could probably reduce TX power here by some 27 dB and still get the message delivered with a decent margin to boot :-) Tnx and 73, Rob - K3RWR
Hi Domenico, Thank you for listening last night and for posting the hits on your auto decoder! It was fun looking through the list and seeing all the activity on 490 as well as an earlier hit of a K3

Hi Chris, Ill be glad to document my current EbNaut TX setup. I think a series of PDF documents might work best. Do you have any suggestions regarding where these documents might be posted as I do no
Hi Joe, Paul and Chris, Im wondering if a technical description of Joes LF EbNaut setup might be useful to you as, I believe, you are both using non-linear amplifiers. My system is built around using
EbNaut LF, Thanks to all for the reports on the EbNaut Beacons from VO1NA and K3RWR over this last weekend! Well done and the reports confirm a strong and viable path exists across the Atlantic from
Markus, Thanks for the tip about using a double balanced mixer (DBM) for generating the 180 degree phase shift. It works perfectly and simplified my hardware arrangement with the HP3325A! I did inser

Markus and Stefan, Will also be looking for both of your messages tonight. This should be fun! 73, Rob - K3RWR On Dec 16, 2018, at 13:39, Markus Vester <[email protected]> wrote: Hi Stefan, that's
Hi Stefan, Luis, LF EbNaut, There are several who believe the converter circuit approach is a viable path to EbNaut RX capability. I think three things are needed at this point: 1) Circuits 2) Identi
