With all the talk against the DDS-60 - in less critical applications such as DRM and casual SWL I've found the SR Lite (wideband modified) and a DDS-60 make a...
Hi, yesterday I had my first CW QSO with a station in the UK using Duncan's KGKSDR version 1.1.0.48. Great hard- and software, thanks Tony and Duncan! I...
From Terry, WB4JFI: I have recently moved, and am still trying to find all my magazines. However, I did find a two-part article in the March/April 2001 and ...
Hi Vic, I am using the USB soundcard Creative Live!24bit for RX IQ input and TX IQ output, the onboard card for Speaker out and Mic input. 73 de Bodo, DJ9CS...
Testing is going nicely but it's difficult to rework the little Lite board with changes ....but WELL worth it vs some test rig with leads all over the place...
... Aha! Very nice! would you like to draw simply schematic for interconnection between two soundcards and sofrock? I have Creative Audigy SE Bulk and onboard...
Hi Bodo, TNX for fantastic pix...Great job! 73 Ozzie, w6icm ad9850 <bscholz@...> wrote: Hi, yesterday I had my first CW QSO with a station in the UK...
Thanks to all for your input. Looks like the ARRL design or the HF Packer might be the way to go. Should work with the Softrock RXTX. 73, Marsh, NC7V...
Very nice pictures Bodo and I am quite pleased the RXTXv6.1 transceiver is working properly for you as well as for others who have finished their kit or are...
Hi Vic, my setup corresponds to that of Hidehiko (JA9MAT) you will find in the files area SoftRock v.6.0 docs -> v6 RXTX transceiver info -> RXTXv6.1 -...
Tony, the TX part of my new RXTX seems to be working with the IQ test tones, but Q2, the TX driver transistor, has a heatsink that is getting almost too hot to...
Don't recall if this has been mentioned before. For those of you wanting to try audio coupling (to cut the OpAmp handling BW down), DigiKey now offers the...
Hi Rick, The heatsink on the 2N2222A driver transistor runs pretty warm but so far that has not been a problem. The emitter voltage should be around 1.5 volts...

Hi Vic, My previous answer was incomplete and misleading. I said you need to use 2 sound cards, but this is only with KGKSDR. If you use PowerSDR and if you...
What model? I have not found one for that price, I found some for more money with the price break at quantity 25. Were you thinking of putting the transformer...

Acouple of watts will never be noticed on the receiving end. The Ramsey kit also has a tendancy to oscillate and becomes very hot with no heatsink. If I were...
Under DigiKey look up "MET-09" (as an example) or "Tamura" and "Audio" ...... there are many listed. I was going to put it between the detector and the OpAmp...
Where can I download a copy of Power SDR software that works with the RXTX?? I have looked/searched but cannot find anything newer than 1.41 . Dick N3HKN...
Don't overlook the 5W Pre Amp from http://hfprojects.com which can take SDR output levels up to what's needed to drive their 100W amp. I have built the 5W...
Hi Vic, Jean-Claude, Current versions of PowerSDR and KGKSDR do support operation of RXTX with a single soundcard provided that the soundcard used has a)...
