More ATS-4 Contacts

ATS-4 CQing
After packing up the Timewave again I took the ATS-4 off the shelf and hooked it up.  Some of the 2M Chatter mentioned that 17 was open....hmmm maybe I should have built it for 17M anyway I called on 15M for a while with no takers so I moved down to 20 and worked an actual QRP station, KE4I in AL.  He was running 5 watts to a G5RV and was solid copy to me.  I was only Q4 with the barely 2Watts from the KD1JV rig.  The Beacon mode on the keyer works well and I was reading emails and typing on the blog while it was calling CQ for me.

After the contact I decided to try the rig on a 'real' power supply rather than the Heathkit IP-18 that is current regulated and 'safe' for building projects.  I hooked up a 30amp dc supply and turned the Voltage up to 6 volts and turned the ATS-4 back on.  It was already putting out more power than it was at 12V on the little supple.  I turned it up to 12V while the rig was in the beacon mode and it looked like it was hitting 5.5 watts so I turned it down to about 11V and it still seems to be hitting 3 Watts.  So it seems my low output was just not enough power supply.

Went down a few KHz and called some more and worked KD0V in MN also QRP then heard and worked OK1KW  near 14.058.550.  Milan says he was running 100W to a dipole with his Kenwood TS-940S.  This I believe is 9 QSO's on the ATS-4 from home using the R7 Vertical.

eMail QSL received - Thanks Milan

Hi Paul,

Thanks for the email and QRP connection. Your signals are quite good, but I was disturbed by the local station.
Thanks so much and wish you much success with your equipment on the HAM bands. BCNU.

73 and Best Regards from Prague
Milan, OK1KW"

Sounds like some great QRP contacts, especially the DX. I've been having a great time with a K1 and having no major challenges with stations that I call stateside using a 80m loop 25ft up. Keep me in mind if you're ever looking to offload the ATS4 :)
