Greetings! I purchased a Jupiter from Ten-Tec yesterday. It has not yet arrived but I already have a question, hi hi. I enjoy PSK31 and Hellschriber digital modes. Can the Jupiter run these modes at
25 watts or less is sufficient for this mode. Higher power will simply cause havoc on the band. Ron, wb1hga "got PSK?" _______________________________________________ TenTec mailing list TenTec@cont

Part of the reason for running low power with PSK31 is for improved intermod performance. And the mode is effective at lower power according to many reports. Hellschriber has a duty cycle for a singl
100 W if you BUY there after market fan option for the heat sink on the back of the radio. Walt K8CV Royal Oak, MI. _______________________________________________ TenTec mailing list TenTec@contesti
Oh, and the other option I use is a 3" computer fan ( 100 volt one ) just wired to a power plug and sitting behind the radio blowing air at the heat sink. Lot cheaper :-) Walt K8CV Royal Oak, MI. ___
Jeremy, I have the optional fan from TenTec mounted on my heatsink and can run any power level I choose with it with no overheating. What you have to be careful about is the audio drive...on the Jupi
One of the best investments in equipment I ever made was my EXTERNAL KK7UQ IMD meter. It shows you precisely what's going on with your PSK31 or PSK63 signal (and optionally signal strength). Check it
Gang I know this is subjective but, isn't it better to have fan blow AWAY from heat sink? Ron, wb1hga "got PSK?" _______________________________________________ TenTec mailing list TenTec@contesting

Depends on the shrouding of the heat sink and the fan and the location of the air filter or where you want the grunge to accumulate. I think the heat sink will run cooler (despite the slight added he
No, the thermodynamics favor blowing high (relatively) speed air at room temperature onto the heat sink. 73 de Gary, AA2IZ just heat _______________________________________________ TenTec mailing lis
Efficient modes do not require full power, and if they leavwe the radio in SSB transmit at all times like PSK does, you want to go at half power to make your radio last longer. Remember, the FCC says
