<DIV>All I can see on first impressions is wow!</DIV>
<DIV>Unfortunately I think this is going to be out of my price range, I'm not saying it's not worth the expense, just beyond my pocket.</DIV>
<DIV> </DIV>
<DIV>How does this spec line up with Thor? And are there any tentative price guestimates for comparison?</DIV>
<DIV> </DIV>
<DIV>Once again just curious!</DIV>
<DIV> </DIV>
<DIV>For anyone considering another solution, check Steve Drury's G6ALU, site. I've built 2 of his 20 FET PA, very stable and cheap. The 150W version is next on my list of things to do! - also very cheap - which suits my pocket just fine :)</DIV>

<DIV>***** High Performance Software Defined Radio Discussion List *****</DIV>
<DIV> </DIV>
<DIV>Whilst at Dayton I had the pleasure of meeting Mike Dishop of Dishtronix.</DIV>
<DIV>Mike was exhibiting a state-of-the-art solid state QRO linear amplifier (</DIV>
<DIV><A href="http://www.dishtronix.com">http://www.dishtronix.com</A> ). His design has a number of unique features, a</DIV>
<DIV>number of which are patent pending.</DIV>
<DIV> </DIV>
<DIV>Mike's amplifier consist of a number of 600w modules that are combined</DIV>
<DIV>together to provide 2.4 kW of output.</DIV>
<DIV> </DIV>
<DIV>I suggested to Mike that he may like to offer the 600W module as a stand</DIV>
<DIV>alone amplifier assembly, including SMPS PSU, Low pass filters, T/R</DIV>
<DIV>switching, etc for use with Penelope as a high power linear amplifier.</DIV>
<DIV>Mike's can provide a module that only requires 1W of drive and since we can</DIV>
<DIV>provide all the</DIV>
<DIV>control signals he needs from Penelope and Ozy it is well matched to our</DIV>
<DIV>needs.</DIV>
<DIV> </DIV>
<DIV>The 600W module has the following specification:</DIV>
<DIV> </DIV>
<DIV>- Completely self contained with integral low noise Switch Mode PSU, 110 -</DIV>
<DIV>240v ac input</DIV>
<DIV>- Integrates with Penelope and Ozy for all command and control signals</DIV>
<DIV>- Frequency coverage 160m-6m.</DIV>
<DIV>- Output power 600W PEP</DIV>
<DIV>- Third Order Intermod at 600W -36dB below PEP</DIV>
<DIV>- Drive power 1W PEP nominal</DIV>
<DIV>- Harmonic output at 600w > 46 dB down</DIV>
<DIV>- Tx/Rx time (using antenna relay) 10-20mS, (8mS with vacuum relay</DIV>
<DIV>option) , (3mS with PIN diode option)</DIV>
<DIV>- Integrated SWR sensor, T/R system (SO239 for antenna, BNC for receiver),</DIV>
<DIV>High capacity cooling fan.</DIV>
<DIV>- Size 10 x 12 x 12 (HWD), estimated..</DIV>
<DIV>- Availability - approximately 3 months from order</DIV>
<DIV>- Price - $1,500 - $2,000 depending on total number ordered, final</DIV>
<DIV>specification features, etc.</DIV>
<DIV> </DIV>
<DIV>Mike will answer any questions relating to the module on this reflector.</DIV>
<DIV>We will shortly be adding a facility to <A href="http://www.hamsdr.com">www.hamsdr.com</A> to enable you to</DIV>
<DIV>express interest in purchasing one of Mike's amplifiers.</DIV>
<DIV> </DIV>
<DIV>I have no connection with Dishtronix - I'd just like one of his modules!</DIV>
