Re: AGC #ubitx

 

My guess:

Some people don't want it, and many will want to do different implementations.? If you search this forum for AGC you'll find lots of ideas for both RX and TX processing.
AGC #ubitx

 

What was the reason, that AGC has been excluded from final "factory" version of uBITX?

There is enough room on PCB and cost of parts is marginal.

Lawrence,
Fiddler on the Roof has a song for you about tradition. :-p

Plus the PTT switch and being able to switch radios easily.?

I'm using a Baofeng on my bitx40, I need a different option on my ubitx as the two independent jacks (3.5 and 2.5mm, a precise distance apart) sharing wires between mic, speaker, and PTT is making soldering a gigantic pain.?

Single panel mount RG45s are available in female to female, or buy a female to male, cut off the connector and you have 1' leads to play with for $6?on Prime. The female to male mount from inside the case, usually sold for Ethernet applications.?

The $20?"quality" Baofeng mic and two $8?jacks vs $35?Kenwood mic and $6?Ethernet jack, I hope the Kenwood is a viable option.?

You would need an RG45 case mount female connector and would also have to wire it for ptt/mic etc in the case. Just me but I wouldn't use it for the bitx.





BITX40 - frequency spectrum - Raduino irradiation - intermodulation products - #bitx40help

 

Hello everybody,

while checking the ouput-signal of my BITX40, I found some nastygram signals in the frequency spectrum.

Interestingly the emission is at the begining and at the end of 40 m Band nearly clean, respectively the distance to the wanted signal is > 40dBm? - but? abt. +/- 70 kHz around 7.100 kHz.
I replaced the DDS-Wire with RG-174 Coax but without results.

Do any of you have a solution ?

Hello All,

Changing the driver level of the outpus reduce the carrier to +8.5 dBm and spurs too !
The Pi attenuators on mixers should be reduced to 2.5 dB max (390R/12R/390R)

Re: Got Mine in TWO DAYS! - Case Fits!

 

Yes, that is the Banggood case.? I ordered four to use for a couple of projects.
Re: Holy fast delivery Batman!

 

How do you find out when/if it shipped?
Re: It's alive!

I have not tried it on 80M, but might try that this weekend. If I do, I'll get back in touch with you.

It did come DHL, but I didn't order it. Ashhar sent me a Beta copy, I guess, and I'm writing a "first peek" review of it.

Hi Jack, have you tried 75/80 meters? I'm hoping it's sensitive there as I want to use it by my bedside at night. Also, you must have chose the DHL shipping option, In hindsight I wish I had done that, I have had so many bad experiences with DHL I just decided not to ship that way:-( Twice they have lost my packages in Germany.

Hi Dennis
That's the EF01 Banggood type case, not so ? Good news if so ...I have one coming over

#ubitx How to interpret serial number #ubitx

 

Question: How do I interpret the serial number on the ?BITX??

It appears that it has 3 segments: Alpha/Numeric/alpha ?( F / 142 / h ) ?

Re: 160m on ubitx??

 

Good point for me Bill. Not much heard here in suburban Melb with noise everywhere and no room for a decent receive antenna - other than the local am nets

Maybe a separate rig required for me but thought it worth asking as others may benefit more.

Yes the uBITX rotary encoder has A, B, and Switch leads.

That is what it looks like from the wiring diagram on the HFsignals website.

Cory -- digital is my first love after CW. Used my Bitx40 several times on WINLINK. Worked quite well. The new unit should be even better.
With a signalink, you'll need to put a 1 uf or so capacitor between the mic input and the signalink (transformer) output as DC isolation.

The signalink will drive the relays of the Bitx type devices quite well and I think the newer one has a transitor for that function also.

Gordon

Subject: [BITX20] ubitx easy first radio?

I'm looking at the ubitx as a first radio kit. Is there any reason a
newbie shouldn't be able to get a working radio with it? Is any special
equipment needed to build it?

My primary interest is portable ops and digital modes, what is needed to
use it for psk31? USB signalink maybe?

Soldering iron, heat shrink tubing, hand tools, common sense and a case would help. No reason a newbie shouldn't be able to do it, just pay attention to details and follow the instructions.
