Hi Farhan How about seeing who would be interested? Seems that a lot of people on this forum may be interested. Regards.

On the other hand, if he is interested in VHF and UHF, then the Rigol DS815 with tracking generator is best. He will also need a variable attenuator, a fixed power attenuator, a dozen cables and an audio tone generator, an RF two tone generator. These accessories are all easily build at home. About 5 years ago, when the specan bug bit me (while doing the Minima), I looked around for a used specan. I finally located one in bangalore for 100,000 rupees (about 1500 usd). I was almost ready to put down that money when I decided to try building one for a month before buying one. I ended up building the specan. I did ultimately buy the Rigol specan too as I needed UHF coverage for building the exseedsat. If there is sufficient interest, we all can pool efforts to produce a kit for the specan. We should shoot for an $100?bag of parts and PCB. The unfortunate challenge of building the specan is that it needs extensive shielding. Hence a particular layout, with shields, is mandatory. This maybe out of thr capability of thr current 'paint by numbers' team of HF Sigs. Happy Diwali to all! - f
