The Orion Crystal filters are roofing filters and not IF filters. The PBT will adjust the DSP IF filters. The DSP filters will lie entirely inside the roofing filter passband. Carl Moreschi N4PY tune
Well said, Duane. To put it yet another way, the purpose of the 9 mhz filters is to reduce or eliminate DSP overload caused by very strong adjacent channel signals not in the DSP passband.
Mark, I believe it does mean that. There should be enough control from the microprocessors to accomplish that. We will know for sure when we get one. Carl Moreschi N4PY PBT inside PBT
Mark, The tuner algorithm goes like this. You tune to where you want to be and then click "Rcl" to recall the tuner settings for this frequency. The SWR is checked and if the SWR is less than 2 to 1,
The 580 Delta does not have any connections for interfacing to an amplifier. It is possible to use the "T" line which is on the accessory connector and make an amplifier interface. If I remember corr
The Jupiter screen should stay at showing the "Pegasus Horse" all the time the jupiter is in emualtion mode. If it changes back to showing frequency and mode, that means the PC program has stopped "t
The tuner power level is controllable witha separate power slider that has a 10 to 50 watt range. This power level is only used when the "Auto Tnr" button is clicked. When normal transmit is done the
Years ago, when the Heathkit HW-8 was popular, I had one of these rigs running mobile in my car. I had a home made 6 foot whip antenna on my car and had it tuned to resonate on 15 meters. Very often
Also, the rx320 does not have a TCXO. It drifts a few hundred hertz for an hour or so at startup. The Pegasus and Jupiter are rock stable right from the start. Carl Moreschi N4PY
I just took a look at the programmer's reference manual for the Argo V. Two things surprised me. The serial port baud rate is 1200 baud! And different from the pegasus and jupiter, to set a different
There is 100 db of AGC built into the DSP section. The AGC in the diagram is just the analog part of the AGC. The end effect is the DSP filters are in the total AGC loop just fine. Carl Moreschi N4PY
All well regulated power supplies have this sense line. But in most of them, the line is internal. It is a simple mod to bring this sense line out of the supply and make it external. Carl Moreschi N4
It sounds to me like your internal pot for the ALC is set too high in OMNI VI. I don't remember where this pot is, but there is an adjustment to automatically reduce the drive to the 100 watt level.
I read the programmer's guide that tentec supplies on their website. It has a lot of information in it about the theory of operation of the pegasus. Carl Moreschi N4PY is really speakers of than slig
My experience with my Omni VI was the 250 hertz filter did indeed have much more loss than the 500 hertz filter in both the 9 mhz and 6.3 mhz position. There is a jumper to compensate for the 500 her
My plan is to offer a new version of my software to control the Orion standalone or the Orion and RX340 in combination. There will be so many new things in the Orion that it does not make sense to en
Dave, There is no receive only antenna jack on the Jupiter. There is a relatively easy way to make a mod to the jupiter to make a receive only antenna jack. If you get a jupiter, send me an email and
Jim, You can mate the Jupiter and rx350 very nicely with my software. The rx350 becomes the subreceiver. You can also do this much less expensively with the Jupiter and rx320 or the Pegasus and rx320
