HEO's are generally *EASIER* to work than LEO's.\n\nThat one needs expensive equipment to work an HEO is a myth that is simply *NOT* true. - (try telling GM1SXX it's expensive) - it's his pet niggle.\n\nPersonally, I've worked the world on HEO's using an FT-290 and an FT-790, both of which are 20 years old and purchased used on Ebay - neither rig has bells and whistles, no automatic doppler tuning and no computer interface. I used an El Cheapo Japanese azimuthal TV rotor, fixed elevation and a maximum EIRP of 25 watts ... yes !!! - E.I.R.P.\n\n(see \"How much power is enough\") <http://www.observations.biz>\n\nI have satellite QSL's from all corners of the world.\n\n(The world doesn't have corners twit, they're \"round\"......GM1SXX).\n\nThings like aerials, a preamp and a 5 watt PA were all home made.\n\nDespite certain schools of thought, circular polarisation is *NOT* a necessity.\n\n(A further discussion of circular polarisation can be found on the OBSERVATIONS website) - <http://www.observations.biz>\n\nExpensive to work an HEO ?? ... Gerroff !!!!. It's only expensive if you absolutely must follow the route of - Mine's bigger than yours\" mentality.\n\nBTW Ib - (OZ1MY) - I agree with most of what you say but would like to point out that not everyone who would like to operate amateur satellites can afford a rig that supports auto doppler tuning if one moves to higher frequencies for LEO's as you suggest. Radio amateur satellites ought to be available to all amateurs - not just the affluent ones. \n\nAs station \"developement\" I used the excellent ITUNE software and a homebrew interface via the push-buttons to give the rigs auto-doppler tuning for full doppler tuning at the satellite.\n\nAgain - as cheap as chips - (those you have with fish).\n\nExpensive ? ... difficult ? ... Ballcocks !!!!.\n\n73 John. <[email protected]>\n", "attachments": [] }
