Re: Second batch of uBITX shipping?
#ubitx
Ordered on 01 february at moment i don't have notice if rtx was sent.
i think there are problems with the orders, this is the answer:"It will take few weeks for the order to be shipped. Tracking details will be updated once the shipment is done"

Re: uBITX Firmware (CEC) 0.30 released (Test version).
#ubitx
Good morning Ian,
With the CW TX->RX Delay set low 0-140 the extra dit/dah is random, with it set higher it becomes more pronounced. At the default 600, it would give an extra dit/dah after every release of the paddle. I have not made any modifications to the radio, just added the resistors inside my paddle and moved the dah wire to the dit side of the jack (internal to the paddle).
I'm no CW wiz, just a guy testing out his radio to make sure everything is working.?

Re: No power increase with higher voltage?
More follow-up. Voltages are all approximately what is shown in the K7AGE table for the Q13-15 devices, slightly less as I have 11.5v out of a regulator to the main board. I bypassed the regulator and ran the main board off the incoming supply, about 13.5v, and no real change other than some voltages were slightly higher. I checked in to a 40m net with a station about 450 miles away, and there is no observable difference between "high" power and standard power, confirming that "high" is only a couple of watts lower. He commented that the audio sounded good (I have made the VK3YE type of mod, ending up with 30pf).? I also have a 100pf NPO cap across L7, but I don't see how that should change things.
Truly a puzzle.

Currently, HF Signals is processing
orders from around 18 December.?? This suggests a backlog of 6
weeks or more.
On the other hand, orders may have tapered off after that date,
since the HF Signals website says somewhat cryptically:
Shipping
will start ex-stock in by Februry end, until then the orders
are being booked in advance
This suggests that they have a good idea when they will have
caught up with the significant number of back orders.
So, I would suggest that a couple of months wait is likely.

No very helpful for diagnosis unless you spell out pin numbers.
Start with the SQUARE PAD as pin 1 and then clockwise 3 5 8 - 9 12 14 16

16-14-12--09
The in between pins are not there..

Jason
I have been using my uBITX with no modification at all.?
I have not found yet a problem with the both settings.?
Maybe it's a bug I could not think of.
CW TX->RX Delay only sets the value so that it can be switched to RX when all CW transmissions are finished. Normally, it should be over 500.
And I have found a bug that is separate from this problem. The 'CW Start Delay' was not reflected in the new CW Key logic.?so, the CW Start Delay value in version 1.01 does not affect CW key operation.
This will be corrected now and will be included in version 1.02.
Could you tell me more about the meaning of "extra" in your message?

Re: uBITX Firmware (CEC) 0.30 released (Test version).

Jason. Thanks for your information. Can you send me your settings?
If you send me the set value, I will test it together.
CW Speed (5th Menu), CW TX-> RX Delay (5th Extra Menu), CW Start Delay (6th Extra Menu) CW KeyType (7th Extra Menu)
--------------------------------------------------- Please ask for the test as shown below. CW Start Delay: 0? ? This is because the key value can be lost because the key and TX start at the same time. According to Beta tester, 20ms is optimal, however which differs from user to user. Setting it 0 up will make you feel like before. ? ?When using an external device such as a linear amplifier, it is better to increase the value.
CW Speed : 12~25 (you want) CW TX-RX Delay : 600 (May be default value)
CW Key Type : IAMBICA or IAMBICB
------------------------------------------------- Additional Information
Version 1.01 can be used with all resistors.? By default, it is set to the range specified in 10K, 2.2K resistor and original source. If only CW Key type is selected in the menu, you can use Paddle or Straight key.
I recommend that you use the ADC Monitoring function in Version 1.01 to make a note of the exact ADC value of Dot and Dash. And adjusting the ADC value range of the CW Paddle in the uBITX Manager will probably be much better.

Hello,
I am enjoying ver 1.01 of the firmware very much. When I wired up a paddle with the 2.2k resistor on the dit and 10k on the dah. I notice an extra dit/dah when using the paddle.?
Not sure if anyone has noticed this or did I miss a post about this?

Nope, it is still there. Just not as bad.

Re: uBITX Firmware (CEC) 0.30 released (Test version).

OK,
I think I figured it out if the CW TX->RX is set 140 or up you get the second dit/ dah when you release the paddle.?

Re: No power increase with higher voltage?
I should have made note that all my tests in the opening message were in to a dummy load and reading on a dual-needle wattmeter with a 30w full scale reading. No reverse power was seen.
I tried reducing the drive, and succeeded in only reducing the power out similarly on both high and low power settings...say 3w on 13.5v and 2w on 24v, or something similar. I had to increase that drive from mid-scale right after replacing a failed Q13 with a 2N2222A that I had available.
I sort of ran out of steam today...brought back a bad cold or flu from Frostfest, the first hamfest I attend each year, but I may try to develop a table of voltages to compare to K7AGE's list and see if anything stands out. Interestingly, the current draw by the PA drops from just over 1a at full modulation at 13.5v to about .95a with the 24v supply. I feel something must have changed as I was reading an appropriate gain that matched the square of the voltage ratio before.

Re: No power increase with higher voltage?
If the idling current is set high it may be possible that the two RFC's in the
IRF510 stage are saturating, making them look more like wires than like
inductors.

Is there any difference in the distance achieved with QSO's
using 12v. vs 24v? Or is there any difference in the reported
received S level when using 24v vs 12v?
There are several possible explanations.
1) There is oscillation at 24v and this is contributing to a false
sense of power output. It is most likely being removed by the LPF.
2) There is insufficient drive at 24v -- This is usually corrected by
increasing the mic gain. For a good solution, see K.P.S. Kang's
solution at .
3) The LPF or output? transformer is killing the signal. This is unlikely
since it works at 12v very well and no one has reported anything similar.
4) There is really no 24v on the drain of the IRf510. This is unlikely
since you are reporting a good voltage there. (Incidentally you mixed up
source and drain).
6) Your measuring equipment is not telling you the truth. Really, you need
an oscilloscope to measure the true RF output at each stage. A good RF
probe will do the same thing, however, and it is easy to homebrew.
Why are you using a DVM to measure RF?
Since you report good audio with QSO's, I suspect the last, though I would
not discount oscillation as the culprit. You need to know the RF level at each stage
through the PA system from drive to output at the antenna. It is also possible that
your antenna is not matched well enough. (That would mean mysterious increased
heating of the heat-sink at 24v; you probably should increase the size of the
heat-sink anyway if you are going to use 24v. Easy enough to do.) Measure the
SWR at 12v and 24v, BEFORE the antenna tuner (if it is used) and AT the antenna.
Really, I think you need to rethink your measuring equipment first.
