 Although there has been some discussion of the Apache-Labs ANAN-10 is a 10+ watt HF + 6M Software Defined Radio multimode Transceiver based on the hermes platform, I am yet to read anything on the new Russian Zeus ZS-1 which purports to be a HF all-mode fully software defined transceiver with direct sampling receiver, direct digital synthesis based transmitter and USB 2.0 interface. (Little concerned about the USB interface as didn't think it fast enough)

Currently have a Flex 5000 and KX-3 but interested in a second SDR for QRP use and wondering whether the ANAN or the Zeus (or some other) would be the best.

I saw the SSB Zeus at Dayton this year, and got to play with it a little there.  It was a nice design. But I was attracted to the open architecture of ANAN radios.  The Zeus radios came with software written by a third party in Russia.  It was a very simple design, but appeared to all modes including digital modes.  I went with an ANAN-100 with its PowerSDR.

Hi all!
I'd like to write some words about ZS-1
ZS-1 developed by PARS LLC in 2010. www.zs-1.ru, groups.yahoo.com/group/zs1sdr.
From this year SSB-Electronic manufactures ZS-1 in Germany under license from PARS LLC. And sales it worldwide.
We are constantly trying to improve our software (ZeusRadio) and bring new features in it.
Soon we are going to release new version with a "better" look. Smiley

BTW, we are still working on firmware too. Always trying to realize new features in the same hardware. Thanks to DUC/DDC SDR technology...
For example, starting from the spring 2013, ZS-1 has built in digital predistortion for TX signal. The worst IMD at full output power is -40 dB.
You can find more results in our yahoo group or webpage.
Here is a screenshot of ZS-1 full power (15W) output TX signal with previous "software look". At RX side of course.

Since you shared this image, I am curious to get your take on the signal bleed showing on the bottom of this image you shared in the waterfall.  What is causing the signal to bleed outside the filter width horizontally?

Actually nothing... One ZS-1 was in TX mode with filter width 3kHz on 18100kHz.
Another ZS-1 was in RX mode on 18095kHz. RX filter was shifted just for better view.
I hope i understood you right...

I am talking about the green horizontal spikes extending out the  sides of the red TX block in the waterfall.

Waterfall dynamic range is set using band noise level. And even a couple of dB causes such green lines.
Maybe slight mic overdrive...
On screenshot is just simple mic noise amplified to "full power".
Plus there are problems with USB hub speed. Both ZS-1 were connected to one USB hub, and it easily handles only one ZS-1. With 2 devices delays in data transfer can appear => noise pops up => green line on waterfall.

Thanks, its not unique to the Zeus which is why I asked, I wanted to get your take on what it was. 

I have had my eye on the Zeus for a while.  I wish I could get my hands on one to play with.  If you ever want a review of it I would be happy to take a lender and ensure it gets back to you.

I am working on a new SDR focused Website Portal and that would make a nice feature article.

You can download and try it even without the ZS-1, just using an IQ file.

I just purchased a ZS-1 from Vibroplex. I am very happy with it and would be happy to answer any questions you may have. You can email me at mweilb@gmail.com
