Re: query re Memory Manager & CEC mentioned in many posts
#v6
Evan Hand
Andy,
To be clear, The CEC software from HamsKey.com (KD8CEC) does not work with the version 6 (v6) display. The v6 driver software required takes up a significant portion of the available program memory in the Nano on the Raduino. That leaves little room for the enhanced features of the CEC software and vise versa the CEC software takes up most of the available memory beyond the base functioning of the rig control. So in my opinion, unless you want to buy a new screen, then the CEC software is not compatible with the v6. It DOES work with the rest of the version 6 IF you change out the display to a Nextion 2.8" as Mike G4GOU stated in his message. You should do the research on the different sites like hamskey.com, ubitx.net and general internet searches before you decide to upgrade or change the stock version 6 ubitx. For the prior version the choice to go to the CEC software was not a significant cost and could easily be reversed. The CEC software would work with the (at that time) standard 2 line display (16x2). There was also not a graphics option like either the version 6 screen or the Nextion screen that CEC provided. Of course there was extra cost to purchase the Nextion screen then as well, however the cost of the kit was less by about the amount of the Nextion screen (ignoring the case which had to be purchased from 3rd parties). Above are my attempts to clarify your choices and provide some of my interpretations of options. Please be sure to do the research, as there are many who will have different opinions that may closer match what it is that you want. 73 Evan AC9TU

Hi,
Just use very thin wire for outside. That will probably deter theft. I've even used a single strand from an old ethernet cable (there are 8 strands inside). You can solder pieces together if it is too short. Or you can buy some 26 or 28 AWG magnet wire which is hard to see and low priced for the length. Also, you can get copper coated steel wire. Maybe it won't get stolen if you put a tag in it indicating it is not copper wire but just steel with a copper coating? Best of luck, Mark

Hi,
I assumed you had the radio in SSB mode, but maybe Dave is correct? How do SSB signals sound on the radio? Good and similar to other SSB radios? The BFO is not for setting the correct transmission/reception frequency, there is a separate calibration for that. 73, Mark

Use a steel wire rather than copper.
a half wave end fed would be 64-65 feet for 7mhz and higher frequencies. 33 feet if you want 14mhz and above. if you are up high enough you might let it drape down. Need a 49:1 unun to connect it to coax. If you can put one end on the roof and one hang down you can run a vertical dipole. The amount of radiation that the uBITX puts out would not be enough to harm although there is enough voltage you wouldn't want to touch the antenna while transmitting. There is about 60v of rf on the wire as measured by my old oscilloscope.I imagine that the receive quality inside would be severely diminished due to noise. -- 73 Dave ADOB Raduino bracket and Ham_Made_Keys

If you have a balcony you might be able to get away with using
HAMstick radiators (ie a different one for each band). I used to
use a modified CB mag mount antenna on 15 M back when solar prop
was a bit better and was able to work many missionary stations in
South America from Canada with that. The metal guard rail on
balcony served as ground plane. It was one of those 3 section CB
antennas with a base section radiator, then a carbon
composite/center loading device, then top radiator. I removed top
radiator and replaced it with a full replacement uncut 60" VHF
stainless whip. AA-30 showed resonant mid 15 M band so worked well
for me. I suspect one could change the feedpoing radiator mount to
a threaded one that would accept the hamsticks so one could have
access to more bands as well. Over time I have collected the
complete set from 80 thru to 10 M as well as a cut down CB
fiberglas whip to work on 6 M. I use them for HF mobile don't see
why it would not work on a mag mount on a balcony rail also.
Probably have to stick to 40, 30, 20, 17, 15, 12 &10 M because
ground plane restricted by rail length I used a manual MFJ ant
tuner also with them. They arent super expensive either and one
could likelyhave good success with just a 40/30/20 & 10 to
begin with as 40 would likely serve for 15M as it is 3rd multiple
of 40 M freqs. I think MFJ sells the sets and elements now.

I have a uBitX v6 and have updated it with a Nextion 2.8" display, I use the 1.200 version of the KD8CEC software and Manager Version 1.11 which work well together.
I have also added a second Arduino and loaded it with dspmeter v0.8 and added the S-Meter with no problems noticed. As far as I know it's not possible to use the TFT display that comes with the uBitX (it has a parallel rather than a serial connection). 73 Mike G4GOU/EA7KIP

Depends how aggressive you want to be. Organize a high voltage to the dipole (both legs unless balun-isolated), switchable instead of the rig while not in use. A few kV should do enough damage to deter any unwary adventurous thief. Even ordinary mains gives a nasty shock if thief should be barefoot, particularly ZL's 220V. :)
... and some bending can be tolerated - but will detune the dipole. If you compensate with a Tuner, be aware that it will only make the rig happy - it will NOT restore efficiency. 73 de ZL2DEX

The CEC software allows calibrating the S-Meter through the Memory manager when using a simple amplifier circuit, and I did adjust mine until it generally agreed with another commercial receiver. However, when I changed to the second Nano and the standalone analyzer the readings presented seemed to be pretty close as programmed. I see in the program you could adjust values and recompile it, but given the limited resolution of the display it seems good enough as it is.

Too bad you live in a place where wire will be stolen.
The big issue I has when I used my deck railing to support a stealth antenna was all the noise from the electronics in my house. A Gell cell battery charger and the power supply for my cable modem were the worse sources of loud nose that overpower all by the strongest received signals. I got rid of the Gell cell charging arrangement and was able to fold an aluminum "mini muffin" pan around the cable modem power supply. Then I experiment with the best ground location. That turned out to be the ground at the connect where the CATV cable attached to the modem. So an antenna in your apartment may compromise your receiving ability. I was able to just use lengths of speaker wire. Fairly thin, maybe 22 or 24 gauge, with the two wires connected in parallel for each length of the antenna. Would it be possible to run an antenna with thin wire that would look like it wasn't worth the time and effort to steal be a possibility? Of course, calling attending to something that may be in your apartment could be another issue. In my case I just wanted the antenna to be somewhat stealth, so no complaints from neighbors about imaginary TV signal issues, and the low cost of the speaker wire was nice, also. But I didn't have to worry about the antenna being stolen. I'm sure there will be many suggestions on antenna solutions, here. Tom, wb6b

If we use old raduino with 16*2 perhaps the memory manager works.
With graphic
display implemented by Farhan, I wonder whether CEC manager works unless he make up a new version for it. sarma vu3zmv

Hi,
The CEC software was an enhanced version of the software that came with the uBitx transceiver from the factory. You could reprogram the Nano in the uBitx with various different firmware from different people. The memory manager software let you set the various things that could be set using the menus plus many other settings for the uBitx software. This CEC memory manager was written to work with the CEC uBitx software. The memory manager was so called, because the CEC software put the settings in known locations in the eeprom memory of the Nano. The memory manager would you change the settings with menus running on your PC and then it would directly reprogram the Nano eeprom with new value to the memory locations that the Nano CEC uBitx software used to read the same settings from. There were some different version of the Memory manager to be in sync with different versions of the CEC uBitx software. I do not know the state of the compatibility of the CEC software and the memory manager with the v6 uBitx. I'm still happy with my v3 uBitx. Surely someone will know the answer to that. Tom, wb6b

Re: uBitx v6 Microphone

Ja dat deed ik, maar misschien moet ik het opnieuw doen. Het klinkt als een hoge toon. Door te zenden op verschillende frequenties, laat mijn yupiteru-ontvanger zien dat de zendfrequentie correct is.
Maar bedankt voor de tip, ik zal het opnieuw proberen. Met vriendelijke groet Rene Nederland

I was offered a complete V3 from a kind ham. I have a dilemma now that I have a rig.
I have a half wave dipole and I live in an apartment. My landlord said I could hang it outside and run coax in to our apartment, however I live in a bad place where copper wire is going to get gone. Seeing as I will only be putting out 10 watts I was thinking about just hanging it inside as I wont be pummeling us with radiation constantly. However it doesn't seem that we have many long enough straight line distances to string the dipole up. My question is this, what will happen if it bends at all? I am going to try and make it straight across from one room to the other with minimal deflection but again, I am in a small space and I dont want my nice dipole stolen. Chris KF4FTR

What were Memory Manager and or CEC software used for? Were they optional add ons that could be useful in #V6 machines?
I see them mentioned a lot in posts but not in sufficient detail to get what they are all about. Thanks Andy 73 & gud DX

Audio feedback during transmit on 20m?
Kaushik Sanghvi
I'm having audio feedback during transmit through my external speaker on 20m
only on ubitx v6 I hear my voice (distorted) on the receive side when transmitting on 20m band.
Thanks,
