Re: Transverter

 

There' was/is a discussion thread in Dec. 2020, with 48 message posts, called

"External amp keying"

The picture was posted in that thread.? The thread was about the same problem.
I think that's why Groups.IO has a 'search' function for finding things in the postings.

Last resort would be manual PTT.? I don't think it will come to that.

It does both, keys the radio and will key an external device.. via the CE-19.
I did find this in the files area of this group. /g/X5105-Users/photo/0/74360.165.0?p=Created,,,20,2,60,0
That looks like the PTT circuit in the CE-19.? Thanks to whoever did that. Saves my eyes.

Does the PTT connection on the ACC socket actually 'send' (for lack of a better word) the PTT signal to an external device?? Or does that connection allow an external device to put the X5105 into transmit mode?

Just 2 WAGs - good luck.

4 vdc in receive, 0 vdc in transmit on the radio ACC jack.
The CE-19 has 0 V on both receive and transmit, leading me to believe it's just a relay contact.

I dug out an optoisolator from the junk box and it's plugged into a breadboard now.? I want to come up with something that is built into the
cable. It's not the size of the CE-19, it's just that it's one more part and more cabling to mess with. I like things small, compact and all internal if possible. I'm thinking optoisolator, and/or whatever else is needed, in shrink tube on the cable.

I'm packing the radio up and heading out on the quad this morning so doubt much will happen till tonight or tomorrow.?

btw, my IC-706 reads 4.5vdc in receive and 0vdc on transmit. It works fine with the transverter.? The one difference is on tx, the 706 reads 4.6 ohms, where the X5105 reads 120 ohms across the acc ptt.? I don't see how that can put the transverter into transmit as soon as it's plugged in, but whatever. I'll come up with a work around.

What is the voltage on the CE19 PTT terminal when the radio is in Transmit mode?

Also, I meant that maybe what you need is an optoisolator to use instead of the CE-19.
The CE-19 is pretty small, though.? You could use double-sided tape and stick it to the back of the radio.

Re: CW Reader And High SWR Tuner Readings on a Magloop and Buddistick After Tuning

 

A factory reset just removes all settings that you've made and puts the radio back to the "factory default" settings for the installed firmware version.?? It doesn't erase the firmware - you do that, by installing another version.

Use the "Search" function of this group's postings and look for "cw reader" - you'll see many complaints about how poorly it works.? It's useless on my X5105 too.? The only menu settings seem to be "ON" and "OFF".

"high SWR readings after using a New Magloop Antenna and Buddistick Antenna after using the tuner."?
?? AFTER using those?? What are you reading the swr of?
What were the SWRs for the loop and buddistick?

Is the noise level very high with no cable connected to the Antenna jack?

To get useful answers, you need to post more facts and details.

There really isn't much to this thing. 2 smt transistors. 6 resistors, at least 1 for the pwr led, 2 dip switches and a relay. I expected to see an optoisolator but don't.

The ptt line goes to a smt transistor, can't read the numbers, then makes its way to a HFD4/3 relay.? It looks like it just picks up the relay and the relay contacts ground the ptt. Maybe a resistor in the circuit too to drop the voltage to 3v for the coil, but I don't have time to keep straining my eyes this afternoon.

Try? checking the PTT signal level with and without the CE19?? See if it needs an inverter.

That solved it. I'll have to see what's involved in coming up with something smaller just for ptt. I don't want to have to pack the CE-19 and extra cabling around.
Can't be much to it.

Thanks Doug.? I have a CD-19 and have never used it.? I'll give it a try and see if that works.

Transverter

 

Has anyone got their X5105 working with a transverter?? Mine keys my 28/222 transverter from transverters-store.com as soon as I plug the ptt in.? I have the transverter ptt connected to the ptt on the ACC plug of the X5105.
Maybe dangerous situation (dangerous for the radio) with EFHW

 

Just blammo'd the CW on my G90 running it to a EFHW with 49:1 balun, 20ft of coax, no ground/counterpoise. I was testing the balun/wire set up & used the tuner to get the radio to a low SWR. (The wire/balun shows good SWR on 17m w/o the ATU; had the ATU on for 20m). Everything seemed just fine until I lost the dot paddle side of the keyer, then the entire keyer.

Opened the box ('cause that's what hams do, right?) and found two of what I think are 100 Ohm resistors in the keying line (from the jack to the rest of the circuitry apparently open. Toasted. Like little holes in the top of the bits and measure open. (There are other similar looking bits on the same area of the board, all of 'em measure 100 Ohms, thus the contention.)

So way I figure: I blammo'd the resistors with stray RF that was getting into/onto the circuit board via the keying line and nonsense (under 30ft) feedline with the antenna wire & balun less then six feet away. And yes, I already sent Radioddity an email for an RMA; we'll see how that works out.

Being as the X5105 and the G90 are of the same breed, so to speak, I'm guessing that I better not try this with the one remaining functional Xiegu in the shack. Others may want to consider my lesson a warning to not be so goofy as this old duffer.

Best part of all this was (a) thinking about tacking some 1/4W 100 resistors across the busted bits to check and (b) remembering that essential tremor was gonna make putting the screws back in the case just trying enough to test my blood pressure meds.

YMMV &c.

CW Reader And High SWR Tuner Readings on a Magloop and Buddistick After Tuning

TopHat
 

Could anyone advise of the correct Menu settings required for the CW reader to function correctly and actually read and decode Morse. I¡¯ve tuned into several CW transmissions with perfect Morse, only for the decoder to produce garbage on the screen.?

Also having high SWR readings after using a New Magloop Antenna and Buddistick Antenna after using the tuner.

Noise levels are also very high. Can the it be reset. I¡¯m on version 3. I¡¯ve tried a ferrite coil on the feedline 6 turns, and thought that it maybe outside of the band. I don¡¯t have an analyser.

any suggestions please. If I do a factory reset will it go back and remember the update to version 3 or will it end up as a brick.

Thanks

Do you mean S-meter or SWR? I thought RSSI was linked to S-meter sensitivity & SWR measure was a transmit function.?

Thanks Dan! I had missed or forgotten that the 5105 had a code practice mode. Nice work!

Re: Can I turn off full break in CW???

 

Here's a copy & paste from a Xiegu X5105 users manual - "For Firmware V3.0 Edited by KE4RG"

Xiegu X5105 Operating Manual 16
Menu4 Keyer and CW Parameters
Key - TAP to scroll through:
MAN - Select to disable keyer and select manual or straight key.
AUTO-L - Select to enable keyer and select paddle for left hand.
AUTO-R - Select to enable keyer and select paddle for right hand.
TONE ¨C TAP to set sidetone (transmit offset) using [KNOB] (425Hz to 1200Hz).
TAP TONE to save and exit.
QSKTIME ¨C TAP to set CW break in delay time using [KNOB] (0nSec to 1000nSec).
TAP QSKTIME to save and exit.
HOLD QSKTIME to restore default value (100nS).
NOTE: The X5105 uses a relay to switch Tx/Rx. Full break-in is not possible. Set this value
high enough to prevent switching during your normal inter-character time.
QSK - TAP to toggle CW Transmit Enable ON or OFF
NOTE: Set QSK OFF to disable the transmitter and enable Code Practice Oscillator (CPO).

Hope this helps.

yes it has on the cw menu qsk if i recall correctly?
