I am currently at 96 countries DXCC confirmed on 6m and with declining sunspot activty its getting tougher to make it to 100 confirmed....My equipment I use is an Icom 756 running barefoot into a Homebuilt 5 ele Yagi on a 24ft boom @60 ft....I used a 6 ele homebuilt yagi on a 30 ft boom before (my own design).This design made a lot of contacts even as far as Japan..I think I will put back up my 6 ele soon..

I am also active on Satellite (AO 27, AO 51, FO 29, ISS WHEN IN Crossband mode, VO 52, SO 50, AO 40 when she was active ).



Satellites are fun and it really is not all that hard or expensive to get going on them...A Dual band Fm transceiver can even be used for the Fm birds.



My equipment for satellite is the Yaesu FT-847 and antennas are 8 element cross polarised on uhf and a modified 5 ele cross polarised (now 8 elements)for vhf. Both antennas are made by Gulf Alpha Communications.

I also have a Kenwood TR 9000 (2m All Mode).I use this rig in conjunction with an AIDC-3731 Downconverter and a homebrewed 2.4GHZ patch feed mounted onto a 3ft Direct TV dish. The downconverter converts the 2.4GHZ signal to Vhf, and I use the TR 9000 to receive the microwave signals from AO 40 satellite.

If You want to learn more about using Satellite dish antennas for amateur radio use ,check out this site.. http://www.ultimatecharger.com/dish.html
I learnt a lot from this site and also how to build patch feeds for UHF+ bands.

I left the 8 element uhf antenna as it is because it has good gain and I can hear all the birds even without a pre amp inline..However I wanted more gain on vhf so I added on more boom length to the 5 ele and with some designing using YO software ,I was able to go from 8dbd to 11dbd with only 3 additional elements.....

In order to work the Satellites, I need to know where they are. I use a Freeware program named Satscape and it is really easy and fun to use....Try it....Click on the picture to goto the Satscape website.

This is another Satellite tracking software called AgSattrack that I found on the net that is freeware and works pretty good...Click on the picture to goto the webpage to read and download..

There are lots of websites showing how to build vhf and uhf antennas which can be used for satellite operation.

One site that has antenna designs for weak signal work and some info on satellite antennas are found at...
http://www.qsl.net/dk7zb/start1.htm .....I like the designs for stacking 2m antennas for EME..

I am hoping to get active now with EME using WSJT software ...I am in the process of putting up another tower for some stack vhf antennas..

Here are some recordings I have found on the web of myself , making contacts on 6m.

Making contact with ON4AOI
