Dear Pravin, Nice to see your interest in JOVE RX! You could GOOGLE "Jove receiver" and first hand you would get all the info! Except that the Jove Rx kit is a Direct-conversion Rx and definitely I don't have the guts to make a direct conversion at 21 MHz and hence I made a regular SuperHet and it worked first shot! Used 16MHz IF as crystals are available at this frequency and the LO happens to be good old 5MHz VFO !!! As you may be aware all my projects use 5MHz VFO and now we do have a QRP DDS implementation also using AD9833! Details are there on the Blog http://hamrmipl.blogspot.in/ including ASM and HEX files for a 16F628 controller etc.... Thanks and best regards, de dev

Hi Shanmugam, Thanks a lot for the excellent suggestion. This is an innovative idea which can fire imagination of a lot of people who are having a technical flair . It is high time we hams have to innovate and keep the next generation in the game instead of merely drooling about the lack of interest of the present generation in the hobby. People of same interest whether in ham radio or radio astronomy or micro controllers or computer or robotics or AI etc should mingle more and use their strengths in a complimentary way so that we can have a very strong technical base independent of all bureaucratic hassles and can have projects executed for the sheer pleasure of doing the things and see them work ( no profit motive). For me even after 30 years in the hobby and experienced in using various types of off the shelf professionally made rigs and also a professional Scientist in the field of airborne communications for more than 25 years nothing gives more pleasure than assembling a simple QRP and working other stations on it. Fortunately the present day easy availability of components and technical know how should be put to advantage to spur a growth in that direction. Thanks to eBay , Amazon, internet etc almost all ingredients for an aspiring DIY buff are on the finger tips at very affordable price. I feel someone who is imaginative and resourceful should take an imitative to organize people of such interest . Dear Shanmugam I would like to get more information on your JOVE RX project you have done for RRI. Thanks in advance for your time .

| Dear Shanmugam garu, Just to inform that we helped/made a JOVE RX (NASA Design) working at 21MHz or so for some students/research scholars at RRI (Raman Research Institute). This is something to do with Radio astronomy....... There are quite a few similar/simple projects which caught my attention and .... 73, de dev
