Re: uBITX Calibration
Today updated the uBITX to the enhanced 2.0 fom AJ6CU.
Also installed his editor. Now not bad generally CWL 14996 - 5 Hz off CWU 14994.6 - weak CWU 9996.230 - 230 too high CWL 9995.07 - 920 too low CWL 4996.470 - 470 too high I am wondering why the 20 is soo good (separation USB/LSB and other Bands not. Think is a off setting from Frequency and BFO. Checked on CWU 40m 7011.5 was the station - my VFO was on 7010.6 The sensivity has increased, I hear stations from EA. Interesting on 15m I have abt 10 Watt output, had a QSO with Lithuana. 20m abt 6 Watt, 30m abt 9 Watts, 40m abt 6 Watts. With the Editor from AJ6CO its much more convinient to work and much faster. Will continue with them. Thank for your'e tips (ΕΦχαριστω πολη) ?

Re: zbitx getting ready to be shipped ...
If they are processing orders in sequence(?), I'm 80 orders ahead of you - that's 1/3rd of the entire batch of orders (250 orders in first batch).
?
Patience is called for - radios are shipping, it obviously takes time to pack, label, and ship orders, they can only ship so many in a day...

Re: zbitx getting ready to be shipped ...
Many thanks Ken
Your message helped me a lot because with the date of your order, and the number, I can make a more accurate estimate of how the shipment is progressing. At the moment I have only seen messages about shipments to the United States or Canada, in the group. I don't know if they are in order of order and if so, or if it is distributed territorially, and in Europe we still have to wait a little longer. We will wait... good things take time.

Re: uBITX Calibration
Tnx Evan
Yes also here have some other (newer Rigs.)
I had yesterday CW QSO on 20m to Lithuana, on 30m to Germany and Belgium, today on 20m to Belgium and Hungary.?
Power with abt 6 Watts on 20m is enough for me. This Rig schould be used for CW most 17m 20m 30m.
More important for me is that the Keyer works well and that the Rig is easy to handle.
I have here at home shack a FT-991 and a FT-857. Also a FT-991 on my sailing ship. And for QRP /p a KX3 two PFR-3a and soon a (tr)uSDX.?
I sailing to a quite island here in the Aegean sea, spend some days on it, and operate QRP, if it has a SOTA Summit then activate them. I made here a lot of first activation on lonely islands.
Now time for a Siesta...

Re: zbitx getting ready to be shipped ...
I too couldn't find my order confirmation email, so I just waited patiently.
?
Last night I got two emails - one from HFSignals and one from PayPal, both alerting me that my order had shipped with an estimated arrival date of the 26th.
?
For those who think there's something to be gained from knowing, my order was #3251, I ordered my zBitx within a couple hours of the radio being offered.
?
Sorry for the broad email, but I just wanted to encourage my fellow buyers who can't find their order confirmation emails that HFSignals is pushing thru the orders, and you will be notified when your unit ships.

Re: uBITX Calibration
Erich,
?
Very nice work on the case!
?
One mod you might want to do is Allison's power flattening on uBITX.net:
?
?
I do this to all ubitx that I work on and own.? It has always more than doubled the output on 10 meters.? It also moves the 40-meter dip in power to 30 meters.? Reflections from the impedance mismatch caused by the Q90 input impedance cause the dip.? I have determined that this is the cause of the output drop on 40 meters with bench measurements.? If I remove Q90 and replace it with a 50-ohm resistor, oscilloscope measurements verify that the output of the first mixer goes to a square wave at the fundamental frequency.? I have yet to work out a solution to this issue.? I stopped working on the uBITX when the sbitx came out.

Re: uBITX Calibration
Thanks Evan
Today I loaded an old Config from 2022, an hurra I am now only 30 Hz off the QRG. also with TX. The Audio Filter can switch 300 / 1000 Hz. Maybe I make something to bypass them. Maybe the BFO I adjust a bit. Ok will check and try Mark's Software. Just had 2 QSO in CW - from SV8 (I am here on Lesvos) 1. to Begium 2.To Hungary. The RIG makes nearly 6 Watts on 20m --

Re: zbitx getting ready to be shipped ...
From now on, we will accept orders only when we can ship within ten days. That may take another few weeks to get there. On Tue, Mar 25, 2025, 6:28 AM Ryan Wesolowski via <cosmo1stgen=[email protected]> wrote:
