Were those 90 W actually delivered to the load in all cases mentioned? Or it was perhaps just an "incident" power? 73, Sinisa YT1NT, VE3EA _______________________________________________ TenTec maili

Speaking of theory, no power can be delivered into a dead short, and very little power can be delivered to loads significantly smaller or greater than the rated load. This is basic circuit theory, an

Yes, it is, and a fairly large transistors are used, along with some protection. Observe voltage/current limitations given in the manual (13.8 V, 250 mA), and do not forget the protection diode at th

A 1:1 current balun works only in limited cases when its impedance is much higher than the load impedance. Given that most commercial baluns have difficulty reaching 500 Ohms, the application is limi

No, the ADC sampling frequency was independent of the TCXO, and as a consequence, all DSP-related RX/TX frequencies were independent of the TCXO. 73, Sinisa YT1NT, VE3EA _____________________________

It depends on how you do it. In Orion's case sub-Hz accuracy is achieved easily by beating two tones of similar amplitudes, that is, the SPOT tone and the received signal's tone. No S meter is needed

With equal amplitudes we have: COS (x) + COS (y) = 2 * COS ((x + y) / 2) * COS ((x - y) / 2) Example: freq 1 = 800.10 Hz freq 2 = 800.00 Hz what one hears is an 800.05 Hz tone with its amplitude vary

On the contarry, I find it very reasonable to adjust BW, RIT or something similar while sending in order to ensure better reception. 73, Sinisa YT1NT, VE3EA __________________________________________

Of course it IS a problem - it may be too late. Most of other radios make it possible, so it's probably not a top notch science anyway. 73, Sinisa YT1NT, VE3EA ______________________________________

This condition is not automatically satisfied by using an open wire feedline. A common mode current may exist on open wires just as easily as on coax. The open wire feedline owes its "low loss" prope

In order to be useful, S meter movement must be synchronized with gain decrease caused by either AGC or manual RF GAIN. That's how it works in "ordinary" receivers. If the current Orion implementatio
