Re: uBitX v6 arrived today - information I found while waiting.

sandjlevine@...
 

Hi, Steve Levine here, KC1ASO. I posted a couple of days ago and whether my newbie post scared people off, or what, there’ve been no responses. 


I received my new V6 last week and was appalled to see no build instructions or anything other than a parts list. There are a number of un-terminated, un-documented wires. 

One bundled group of three (power) had a female pin connector and, like a labeled pair that obviously was going to the speaker pins, were easy to figure out, however . . . 

Consequently the TFT board has eight colorful wires hanging off the back of an eight pin connector these are untinned with no connectors on them. They are unlabeled and quite frankly I have no idea what to do with them.

Am I supposed to intuitively know what to do with these wires?  Is there’s some kind of marking on the main board that I should be looking for?  I’m really confused about how to finish this. As stated earlier, the only thing that was in my box was the cabinet, the speaker, the microphone, a mini USB extension cable, some feet and knobs, a stylus, and a bag of screws  there was also a parts list but that was it. As Bette Midler used to say, “is that all there is?“.

Hopefully somebody will respond to this posting so I can determine what I’m gonna do with this box ‘O stuff  

Do I build it or does it go to eBay?

Going forward, I’ve been reading a lot of the issues that other forum members are having with this radio. It seems that many of them are still using or referring to versions 3, 4, or V5 components. Are these same issues still prevalent in V6?

The HFSignals.com order page has a link marked "ASSEMBLY".  
Click on that and you will find the assembly instructions.  If you 
run into problems with something specific, just ask here on this 
forum and someone will answer with suggestions or comments.

Re: Plan to convert Bitx Ver 06 into all band Transceiver

ajparent1/kb1gmx
 

Watch for spurs and harmonics.  Don't know the rule for VU area but
here USA its everything -53dbc minimum and I think most of EU/VK
the same.

The internal amp for TX is useless at VHF and the RX will seriously need
a LNA for 10M and up.  Solution for TX is individual amps for 4m, 6m and
2M with band pass at input and low pass at output.  IRF510 is ok for 6 and
4M but useless at 2M for that RD15VHF.

If your doing transverters then the power amp is not needed at all as most
transverters only want milliwatts.

Re: Antenna Question #antennas #v3

ajparent1/kb1gmx
 

My first 160M antenna was at a height of one inch (25.4mm)!

It was the K3MT grasswire laid out in the back yard , no way to support
it in the air at that time as a 250Ft dipole is 100Ft longer that property wide
and available trees.  It wasn't a band burner but it did work as predicted
by the author and it was amazingly quiet.  Raised to 6Ft the height of an
average fence it worked noticeably better.  So the top of a wood or the
current fashion plastic fences would work.  I used #24 stranded wire 
from CAT5 cable, hard to see.  It was a decent local antenna for 80
and 40 too compared to the higher dipoles.

Anything can work.

The walkway isn’t long enough.

We did a good job of hiding the dipole and you won’t be able to see where the coax enters soon.

I just want to get on 20 and maybe 40.

Looks good Chris,

How well does it receive? I'm with Gordon and Mark, you will no doubt have problems with that setup do to the fact that the legs of your dipole are tied up to other wires. The SWR will probably be high. My dipole is out in the middle of my yard, yet when I put up a end fed half wave next to my house it actually changed the resonant point of the dipole that was a good 15 feet away, so other things and wires will cause problems. Maybe after the dust settles you could make some changes to your antenna.

Re: Antenna Question #antennas #v3

I remember reading several accounts of people hooking a short wire to their bedsprings, and loading them with a tuner and making contacts - demonstrating amateur radio to a friend (accounts from the 50s and 60s, maybe earlier).  There are many tricks that can be used in such a tough situation to get out (at least to some degree).  A tuner (especially a pi or short-wire tuner) can be easily made, even with home-made materials with a little ingenuity (and if you're in a situation where a landlord INSISTS on the right to "regularly" inspect your living quarters, they can even made to look reasonably attractive.

I think the dipole, even if it's in a less-than-ideal situation, should not be a problem whatsoever (although it might require a tuner for a decent match).  If you're not running a lot of power, the problem with interference should also be almost non-existent.  I knew a person who just threw a 40 meter dipole along the hedge outside his window (unnoticeable) - and got out great, so much so that people were going to see what would happen if they did that at their place, and he certainly was not running anything CLOSE to a full kilowatt!  (There are also a couple of articles about tough situations I've read - where people did things like putting a long stainless or brass screw into a living tree trunk and loading up the tree! As I remember, they did NOT come out in April.)

Anyway, good luck to those in that sort of situation (or who cannot afford the latest and greatest) - and good contacts!  (That's the beauty of QRP, if you can keep from being stomped on by the 'full gallons".)

With all due respect guys, the owner of the property was angry we had agreed to set it up at all. The fact that they drilled a hole in my wall, let me hide the antenna, and do this at all in a slum apartment is a win. Yes I understand it’s not ideal, but it is well hidden and the best I can do for now.

The maintenance manager happens to love cb radio so he was kind enough to let me drill a hole in the wall and fill the hole with foam after installing coax.

Re: Antenna Question #antennas #v3

 

Hi,

That's too bad.  I would have thought the maintenance guy had the approval of the owner.  Anyway, do you have any idea what those wires it's zip tied to are for?  How is your reception for noise?  Checked the SWR yet?

From the picture, it looks like you might have a balcony?  If you do and the dipole doesn't work out, you can always try hamsticks.

Are people emailing you directly or are you talking about emails you receive from groups.io?  You can disable the latter in the settings.  That's what I do, I just use the web interface only.

Cheers and 73,



Mark

Hello Reg,

thank you so much for the wiring sketch, it will for sure be a great help !


I think you are right: I should be able to insert the filter between the AGC yellow wire and its final destination to the volume pot...

I just need to order the filter now, but will wait for the end of the virus crisis as parcel's transportation services will be off or so for a while.

I'll let you know ;)
