Re: D hole plate to fit SO-239 bulkhead hole - SO-239 to BNC conversion
Tom
I looked at what it might take to make a D-hole punch.? Seems that a 1/2 inch
Grade-8 bolt could be turned to the desired diameter and one side ground flat to make the D part.? Then turn the end down further and thread it to serve as
the puller threaded part.? The socket end could be drilled smaller than the
D-section of the punch and filed to size and shape, with a thru-hole for the
threaded part of the puller.
Not really a machinist here, but little metal projects do intrigue me.

Arv,
I've considered making my own. I have a drill press and an arbor press. I've got a good set of greenlee hole punches (the bolt driven punches) but none that are d hole or that small (I think my smallest is 1/2"). I believe greenlee does make d hole punches.
I wonder if Marshal had these fabricated.?
Thanks
Tom

It¡¯s good to use the tools attached to the email where you complain about how to mute a topic....

Hi,
I looked around for the means to mute message threads by subject on
. We apparently cannot do that but there is a hint that we
*can* mute messages by their hashtags. I have added a hashtag to this
thread in hopes that it may help people who have no interest in
reprogramming their radios nor interest in reading such books.
In future I will try to remember to include a hashtag in my messages so
that people who don't like my drivel can mute it.

I used to buy these from Oak Hills Research, however with Marshal Em's passing you can not order from OHR.
It is just a plate with 4 screw holes spaced to match an SO-239 bulkhead fitting and a d-hole in the middle to fit a BNC bulkhead.
There are other ways to handle this conversion but boy does that little plate make it easy.

If you have a machinist friend it would be fairly easy for him/her to? make a D-hole Punch for thin aluminum plate.? Remember old bolt- driven chassis punches.? Same thing works for punching D-holes.

Rajesh, First off, did you follow the suggestions in this message? /g/BITX20/message/80271NOTE: Please ignore the typo Arduion, it should have been Arduino. There is only one file that needs to be loaded into the v3 uBITX Nano with the stock display using the Xloader.? For your situation that would be: UBITX_CEC_V1.200_16P.hex The tft files are used by the Nextion display, that you do not have.? They are not loaded with Xloader, rather they are transferred to the Nextion through a microSD card.?? From what I can understand from your messages, you are not seeing the backlight turn on in the stock display.? That is a hardware issue and has nothing to do with software.? If your setup is working EXCEPT for the backlight, you should be able to read text on the display if you shine a light on it at an angle.? You can adjust the contrast with the P2 control on the Arduino. I believe that you are at the point that the best option would be to find a local club or ham that can help.? I am running out of suggestions for you to be described over the messages board. Good luck 73 Evan AC9TU

Evan, the CEC firmware allows WSPR in beacon mode for transmitting, but not decoding. You use the Memory Manager program to set your location (you can set 4 different locations), and frequency (3 available), and to set the code for your call and power level. Then you enter the WSPR mode by pushing the tuning knob and selecting WSPR, then select your? location choice and frequency. The 110 second beacon is then initiated? at the top of an even minute by looking at your watch and pressing the PTT. It works fantastic and allows you to get reception reports back on your smart phone or on your computer when you get home with only the rig, a portable power supply, and portable antenna. I have used it as a demo at hamfests, at the beach, and to test different portable antenna options. A very clever addition by Dr. Lee built in to all the later versions of his software.

Hi
Thanks for the revert. I use the standard lcd display which comes with the box.
Have uploadrd the corresponding hex files as well.
But still the display does not light up.
Since I have ver3 running currently, ehich is the manager for it. Ver .97 and 1.11 dont seem to be able to read the stock raduino.
Rajesh, did youbuse nextion or 16*2 lcd ?
?Eitherway you have to configure it in ubitx.h file before really uplading. I assume you might have done it.? However try to check . All the best.? Sarma vu3zmv

Possibly one of the mixer diodes is in backwards.?
The original BITX20 had a very sensitive receiver, which allowed? spurious signals to be heard if there was no RF input and if the? volume was turned up way too high.??
What is your MDS (Minimum Discernable Signal) in microvolts? MDS should be in the 0.2 to 0.4 microvolt range. If you do not have capability to insert a clean 0.2 to 1.5 microvolt? signal then ignore that test.? ?
Like all superhet receivers the BFO frequency needs to be adjusted? to between 10 and 12 db down the side of the crystal filter passband. Setting it above the filter passband will give you LSB and setting it? below the filter passband will give you USB reception.? Setting the? BFO within the filter passband will give you DSB reception.? If you? set the BFO too far outside the filter passband your received audio? will be distorted.? where you adjust the BFO relative to the filter? passband will affect the amount of highs or lows in your received? signal, and in your transmitted signal.??

i built the bitx20?original version in 2012 but it functioned very badly
I built it clean with a PCB board (not the ugly style)
But the reception was rather deaf. except from unwanted beep tones. I suspect unwanted mixing products.
transmitting did not function
I made some modifications based on version 3?and i used a computer controlled vfo
the noise is louder and the beep signals are still there
does anyone have an idea how to solve this problem

Hello Rajesh....
If you have taken the raduino out and replaced it various times, I'd double check to make sure one of the connecting pins has not missed it's target hole and is folded back where it escapes being seen. And double check the board's supply voltages to the raduino.
Sorry, this is the limit of my technical guess-work.

I'm not trying to be funny but... If it were me, I'd get a V6 and look at that original version as some replacement parts. I know you are determined to make that work but consider the operating time you lose by "re-engineering" that rig.

Re: Last effort before it is scrapped.....
I searched for the same more out of curiosity than anything. While there are some at near the same price but they only do one band, for the most part. I wanted the range of features the V6 has so I went for it.
If you only want a single band, there are some out there but most are CW only and do not have SSB. Plus, they are not general coverage receivers that can receive from the bottom of the AM broadcast band all the way to about 30MHz. For me this is a huge plus...
The radio is neat, compact, and full of features I appreciate. I have not found another radio that offers so much unless you are willing to pay at least double the price of the V6. Assembly is so easy that I smile when remembering the "kits" I put together from Heathkit many years ago. Even the little TenTec kits were days in the making for most people unless you took a day off and did only that. The Cub is nice but it is CW only and covers only part of a single band that the builder sellects.
With the full kit, you get a radio that can be proudly shown to other hams and many of them will want one. Even competition has to copy many of the V6 features but they will still fall short, I believe, unless they make it their goal to present something with more features than the V6 full kit.
Hackers like it so they can add other features like AGC, etc.? But as it is out of the box and put together in about an hour (reminds me of the Elecraft KX radios), it is better than the TenTec Argonaut at a fraction of the original price of the Argonaut. And the Argonaut only covered 80M and up while the V6 is open for use on the WARC bands, also. I could go on but you probably get the idea. I have built and used many QRP radios but the V6 with all the features has them all beat.
For $200 you get a V6...? And with a box, speaker and microphone? Unbelievable. The only think lacking is a straight key.
Time for another QST feature/review article, I think.

Steven,
Not sure that I can help. however, I could interpret that you have had WSPR running on just the uBITX Nano with the CEC software.? I was not aware of that.? Would you please point me to the location of any documentation that there might be?? Last I had looked on Dr. Lee's site he had given up on putting it in the base Nano, and was looking at other options for a linked processor to do the decoding/encoding.
I have made a number of contacts using my v5 uBITX with a PC running WSJT-X.? For that control, I used the Yeasu FT-857 (I have been told the FT-817 works, however, I had issues with it).? The TX for that setup is controlled with the CAT link using 38400, 8 data, 2 Stop, None for Handshake, CAT in USB mode with none split.
The same setup worked with a Raspberry Pi 4.
FWIW

Hi all,
I'm trying to sort out a problem with WSPR. My uBitX is a v5, nextion with CEC firmware. I built it last fall and by December was enjoying some success with CW, SSB and WSPR. I was getting WSPR reports from Europe and Antarctica. And something happened. One day nothing, no WSPR. I put it aside and now want to use WSPR again and try ft8.
My troubleshooting skills are limited. One thing I noticed was that when I key down for CW or ptt with SSB the TX light comes on. When I try WSPR everything looks and seems right,? WSPR timing included,? except the TX light doesn't come on.Any suggestions. Reloading the CEC software is the only option I can think of now.
Thanks
