Re: uBITX Version 4 first attempt #ubitx-help #ubitx

Group, I have 5 bitX transceivers, 2 Hendricks and 3 from Ashar. I really like my units (all
of them). I have to admit that I did have problems with my bitX40 but that was my fault. My meter was defective and when I went to adjust the bias my meter read zero so I cranked up the drive and burned out my final. I fixed it and all is well. I have to admit that the audio can be improved by adding an agc circuit but that is not really necessary if you just adjust the volume control to suit the strong or weak signal coming in. My last purchase was the original uBitX and this time I did nothing to it. Yes, it can be improved but I haven't done that yet. I am having too much fun using it. I am in Iowa and my first contact was in California and since then I have logged about 15 States. On 40 I spent 10 minutes trying to get through a pile up of stations calling a station in Spain. I think that I could have logged him if I only had a little more time, he was 20 over on 40. I say all this just to prove one point, this transceiver works out of the box without any mods and all you have to supply is power and a case. If I'm getting over 5 watts, I'm happy. If I need more power I have my 100 watt rig and if that doesn't do it I use my Dentron amp for 1600 watts out. Its more fun doing it with 5 watts. Ashar has done a great job getting this unit out to us and we shouldn't complain about his excellent work. Ive seen it all (ham for 64 years) Ed W0OIC

If making the connections to the main board is the source of your discontent, I would say caveat emptor and that you didn't do your homework to find out what the kit entailed. If there is something wrong with the main board, then what have you done to contact HF Signals with a detailed statement of the problem? Finally, what exactly is the nature of your problem. There are several thousand of us loitering around here, perhaps we can help.

None of those mods are required for the transceiver to operate properly.

The audio was not an issue until someone who did not understand push-pull follower circuit biasing proclaimed that the circuit would never work.

I think that Andy is correct in thinking why he should have to do all these mods to this kit!! I also have purchased and built several kits in the past and have never had to do the scale of modifications that are now required to get this kit to work correctly. It was never disclosed on the HF signals website that it will be required by the builder to almost replace every component to make the rig work and be legal on the air.

Why are you Guy's sticking up for Farhan, when he does not come forward and hold his hands up and say that the kit should have never gone to market.If this was UK produced ,then Trading Standards would have closed HF Signals down long ago!!!

No one can expect a builder to rip out components and bodge the pcb to get it to work. This is not a user friendly board as it is all surface mounted and if you dont have good eye sight and the correct equipment then it will end up as a bin job!!

Also most builders do not have the correct test equipment to make tests to insure that after all these mod's, they are legal when on the air with this kit

My biggest beef about all this is that HF Signals cannot deliver a kit to me that is not damaged in the post and please dont tell me I have pissed of the postman, My postman is a nice guy and so are the staff at the sorting office and India to the UK is a very long way

I paid good money for a Bitx 40 and a Ubitx V3 and both were received damaged, a replacement Bitx was sent and that was also received damaged.

When I pay good money, I expect to receive the goods in a usable state and then I do not expect to have to then remove and replace most of the components at my expense, and probably have to wait weeks for these new components to come in, just to get it to work correctly

Firmware updates are acceptable as the nature of the code can led to bugs creeping in and this is a very easy thing to do and does not require butchery of the pcb

This has only come to light in the last week or so, and I’m sure Farhan will be addressing the issue with the audio asap. There are a few “workaround” mods that can be done if you search on here. Just remember this radio cost next to nothing compared to the competition. It was created to be modified anyway so if a small mod is needed to better the audio then that’s not the end of the world.

Sorry for the delayed reply...I was on vacation.

The Q70 mod will only affect extremely strong signals near the receiver's saturation point. My audio on an unmodified board is pretty good, so I think the problem lies elsewhere.

Re: Homebrew from scratch #ubitx

There's a lot to be said for the bus approach to building anything. Remember the S-100 bus in the early computers? Early versions suffered from ringing on the bus, but that was quickly solved and the bus was serviceable for many years. As far as serving as the platform for experimenters like so many of us here are, a bus kinda make sense. Alas, I wouldn't know a "good" bus if it sneaked up and bit me in the butt. However, I'm sure there are many here who do. This might be a fun direction to go.

FYI - I used the same approach when designing the Heath SB103 transceiver chassis back in the early 1970's.  With vertical solid metal separators, we were able to achieve some impressive isolation between modules.  The only wires were to the rear panel connectors and front panel controls.  When we were forced into using tube finals, those had to be wired, of course (we originally did a totally solid-state final).  Everything else was handled by the motherboard.  The vertical separators also gave the chassis rigidity and you could literally jump up and down on the radio without affecting anything.  It also facilitated the design process, since we could swap boards in and out, even using an extender to bring it up above the chassis.  We had a reference oscillator with 1 ppm/year drift (measured) without using an oven, also (my design).

ON6RF developed a very nice PCB with all the modules able to be snapped off, thy had their board on Oshpark or similar, http://soldersmoke.blogspot.com/2017/10/modular-bitx-boards.html 

I think modules are a great idea, because I like to swap variants.  Separate point to point wiring between them should be avoided because it defeats swappabiilty.  The idea really makes sense when you think of with a backplane/motherboard  with all signal and power connections, and pluggable modules separated by screens where necessary.  0.1" headers work at HF.  The module boards can then be vertical.  Surface mount allows them to be tiny.  

Regarding scratch building Raduinos, I have built 4 or 5, using a Nano, veroboard or hand drawn PCB, and the Adafruit si5351 breakout.  All of mine are implementations of the Raduino circuit so I can run any of the community's software.

A screened enclosure is nice but probably not necessary for a simple RF detector as long
as you don't have any long leads on the RF side.  The DC side is bypassed for RF and can
be either twisted wires or coax with the shield grounded.  Many who build their own RF
detector probes do so inside a plastic pen tube or build them in the open on a scrap of
PCB material.  If you do a Google search for RF Detector Probe and look at the images
you should find lots of ideas for making this piece of test equipment.  For intermittent use
it probably does not have to be a work of art.  Just something functional is adequate.
