Awsome. Thanks for the reply. :)

Expect 5 weeks, that seems consistent with recent orders. Also, be advised that lead time could be extended due to delays in part shipments to HF Signals that are outside of the control of HF Signals.
The 5 days seems like a typo, the zBitx has never shipped that quickly (five days from order to shipment notification), that may be the goal once demand is a bit more predictable, but it has never been the case as far as I know.
Good luck,

Re: Satellite software to allow sBitx to monitor and display received signals alongside ICOM satellite radio
Gordon, agreed on all !? There's always more than one way to accomplish the objective, and I think the specific steps are somewhat?dependent on the software you choose. I dabbled with linear sats about 3 years ago, using SatPC32 and the exact method in your previous post, and it does work.
In my current dabbling, I've been using GPredict on a Raspberry Pi to handle the doppler correction.? GPredict does not appear to provide a method to save the offset for future use.? However, DL7OAP has a python script called gp2icom that basically replaces rigctld for the specific combination of GPredict and specific Icom radios, and that script does include that ability.? I've been playing with it a bit.? It has its pros and cons versus just using rigctld.? With that software, you first find yourself?with RIT, and then enter that value into the configuration for future use on that sat.
Part of my goal is a complete portable satellite station.? The Raspberry pi is tiny and takes little power, and I can access it with my iPad (via VNC) so it's headless. I've mostly been tinkering with it in the shack, but I did take it out in the yard a couple days ago as a proof of concept.? I'm not completely sold on it yet - I may go back to a laptop and SatPC32, or I might spring for the S.A.T box from CSN.? A couple of my friends have highly recommended it.? Their approach is to use RIT to find yourself on a given bird, and then save that value in the transponder configuration of the SAT box.? The box is tiny and provides a web interface, so I could use my phone or tablet.
This stuff is a lot of fun - lots of choices !? I'm very? interested in how it all works out for you with the SbitX once you've gotten it all integrated. 73 de W0ZF

=================SATPC32 Frequency Correction & Storage Instructions====================
e.?With analog transponders (satellites which allow SSB and CW operation, for example VO-52) exact frequency data are most important to hear your own signal immediately with the right audio pitch when you select such satellite That will probably be not the case with the frequency data that come with SatPC32. Due to hardware caused frequency deviations these data cannot be optimized for any particular equipment. Sometimes your own signal will not be audible at all with the default frequency data until you modify it slightly.?????
????????
The SatPC32 CAT menu functions, however, allow you to easily determine the optimal frequency data for your equipment and to store them automatically in the Doppler.SQF file. You don't need to edit that file manually.
With previous program version this feature worked only with 'normal¡± SSB transponders (SSB on uplink AND downlink). From program version 12.7 this feature works also with transponders using SSB on the Uplink but FM on the downlink. AO-51 switches to that mode from time to time.
Important:?With the satellites using this mixed mode the SatPC32 control 'V¡± (for 'VFO¡±) must be switched to 'V+¡± before the following steps can be executed!?
???????????????
Please proceed as follows:
(Note: All steps aa. ¨C ee. have to be done only ONCE! They must not be repeated at future program starts!
Note: The following does not apply to the Icom IC-706MKIIG and compatibles and the Yaesu FT-817/857/897 transceivers. Regarding these radios, read the 'Readme(Icom).txt¡±??or 'Readme (Yaesu).txt¡± file which can be opened from the '? |Hints for...¡± menu.

aa.?Select the desired satellite, for example VO-52, while it is in range for your location.??????
?????????????
bb.?Tune the VFO to an unused frequency.?
????????????????????????
cc.?While transmitting and whistling or sending CW signals calibrate the TX frequency with the TX correction controls of the CAT menu or the +/- keys of the keyboard until you hear your signal with the correct audio pitch. With the Yaesu FT-847 you may also use the Sub VFO knob for this step.
Caution: Do not use other methods to find your signal since the program needs to know the amount of correction to change the TX frequency accordingly.????
???????????
dd.?Click the 'Change/Store Data File' button in the CAT menu. In the window that opens click the 'Uplink Calibration' button. The program will then automatically change the TX frequency entry in the Doppler.SQF file. When you select that satellite at future program starts you should immediately hear your signal. Minor remaining frequency deviations may then be corrected with the +/- keys of the keyboard or the correction controls of the CAT menu. If your signal's is too high, click the '+' key, if it is too low click the '-' key??
????????
ee.??With satellites which require an outdoor converter or transverter (e.g.??AO-40 with a downlink on 13 cm and an uplink on 70 or 23 cm) you will probably have to search for your downlink signal because temperature-induced frequency variations of the converter's local oscillator.??These frequency variations can be 10 kHz or more.
?
Fortunately, SatPC32 provides a simple process to correct for daily variations in converter L.O. frequencies.??The result is that you can find your signal easily on satellites such as AO-40. For this purpose the program evaluates the actual beacon frequency to determine the actual frequency deviation of the converter L.O.
????????

aaa.??First select an unused frequency on the transponder. Correct your TX signal as described above (step cc) until you hear your signal with the right audio pitch. Then store the TX correction (step dd above).

bbb.?Tune the VFO to the beacon frequency until you receive the beacon signal with zero beat. Then click the 'Change/Store Data File? button in the CAT menu. In the window that opens click the 'RX/TX Freq. Data'.
?

????????
f.?When you select that satellite (for example AO-40) at future program starts, the program will immediately tune the RX to the expected beacon frequency (considering the actual Doppler shift).

Therefore tune the RX VFO to the beacon signal until you receive it with zero beat. Then click the 'Correct Actual Deviation' button in the CAT menu. The program will then automatically correct your uplink frequency (but will not store that correction value). Tune the VFO to an unused frequency. Now you should hear your signal with the right audio pitch or close to it.
?
Step f typically needs to be done at the beginning of every AO-40 operating session, in order to calibrate the Doppler tuning software to 'today's' downconverter L.O. frequency.??By using this procedure, there is no need to transmit excessively to find your signal on the AO40 downlink.??Your transmit signal should be within 500 Hz of 'perfect' on the first transmission if you have followed these steps carefully.

Re: Please remove me from the group
Amateur radio is a hobby. Amateur radio is innovative, curious, constantly learning, friendly and enjoys teamwork, even if it is at a great distance. Of course, zBITX is not a finished product, it may not have perfectly optimized software, but it offers a platform from which we can learn and when we make a radio connection we are fulfilled. The work of Farhan's team is appreciated by an international community of passionate people, because it offers the possibility of purchasing high-performance equipment at a decent price. Do you want a finished product? Look for a branded product, the fruit of a design team with decades of experience, but the price is in the thousands of dollars. Many amateur radio operators cannot afford that.

Re: Satellite software to allow sBitx to monitor and display received signals alongside ICOM satellite radio
Nice progress Gordon!
I¡¯m far from an expert, having only a dozen or so linear satellite QSOs under my belt, but I completely agree that the spectrum scope and automatic Doppler correction make things much simpler.
I¡¯ve seen people demonstrate two different ways to ¡°find¡± your uplink in the passband. One, as you suggest, is to add or subtract an offset in the uplink frequency until you see/hear your signal coming back. The other is to leave the uplink frequency alone and use RIT on the receiver to find yourself.
Again I¡¯m no expert but it seems to me the latter method would be less annoying to other users on the bird, as you¡¯re not slewing your transmission across the band. ?
I¡¯m still trying to refine my technique to quickly and consistently find my downlink. I have much to learn. I think better antennas and some preamps are in my future¡

Re: Calibration Process for ZBitx?
You can try copying the sbitx/data/hw_settings_zbitxv1.ini file. If you want to change the output power, you can do it according to the sbitx logic. You mean changing the scale value by 20% and measuring the output signal on Dummy load where it can no longer be increased, that is the physical limit of your amplifier. After each increase, you have to restart it to start with the new value.

Just spitballing about how the various people hacking on the zBitx can best coordinate.
On the messaging front, I did try to get that branch installed on both frontpanel/zbitx, and I didn't see that mode added. Is that still WIP, or did I screw something up?
Thanks for all your work!
