Newbie to Flex-1500 - No RX...

  • Question
  • Updated 4 days ago
Just bought a second hand Flex-1500 but I don't have any RX at all...
"PA" is of course selected in "Antenna" but what other(s) parameter(s) indicate the antenna?
Thx and regards.

They will not give tech assistance over the phone. They will repair your rig but it will not be quick and it will be expensive. When you consider that they are only worth about $500 at best, $100 min labor for first hour plus parts and shipping is going to quickly exceed the value of the rig.

Flex is not really give tech support over the phone for any radio. And yes they fully support all radio products as long as parts are there.
But to Lee's point, It may be cheaper to locate another radio to buy. If you stay with the 1500.

Ben,

I think that the problem with your 1500 is that the receiver input protection diode is shorted. This input diode is not used when you connect to the XRVTR input. This diode also will not effect the PA output. It does make the rcvr ant input deaf.

Thank you, very interesting!

So, let's suppose that TX is ok. (on PA port, of course)
How is it possible to TX without "burning" the RVXR port?! (even with 5W only)

So, the next steps on my side are:

1) check if the PA port is working in RX.
Would be a miracle because it wasn't working the first time I tried but I didn't try it after I saw that RX was ok on XVRX port.
2) check if the PA port is working in TX. (would be better than nothing...)
But it means I need 2 different antennas. Well, well...
And what would think the RX to have a TX just next to him (on the same band, of course!) Is there a way to "cut" XVRX while TXing?

And if I get the Flex fixed, it means I have a 5W rig... not very sexy...       :-)
Maybe I'll use it in the end in RX only...

Ok Lee and ok Bill.   ;-)

Just that I'm in Europe and it can change things... I mean, something usually sold 500$ (430€) in the US is, because of that weird calculator which is flying over the Atlantic ocean, sold something like 1,000€ (1160$) in Europe... So, this can change a bit the way we think about the price...

<<How is it possible to TX without "burning" the RVXR port?! (even with 5W only)>>

Not sure my question is clear...
I mean, if I'm using PA port for TX an XVRX port for RX, it's just like I'm using 2 rigs with 2 antennas at the same location.
What if I'm TXing on, let's say, 14,200 while RXing on that same frequency?!

Thx
Ben

I dont think the 1500 will do full duplex which i believe means that when you transmit , the xvrx port is protected. Thats the way it works on my 6400 unless i specifically select full duplex mode. You should be able to verify that in the owners / operator manual.

Thank you Wayne for your post.
I don't think either...

Well, for now, I'm far from this... I'll see that later...     ;-)

Hi Gavin,

you can click on the pic so that you can see it "Full screen". (or go there: https://nsa39.casimages.com/img/2018/08/08/180808090049942031.jpg )
And yes, from my point of view it's a hardware problem too but I have to make some more checks. What is working, what is not...

Ben what are you using to listen to the audio, headphones or computer speakers. Also the VAC can be unselected as this is a virtual audio cable for other purposes

Oups, I missed your post!
I tried all that can be used. The jack on the Flex, the jack on the laptop and the external speakers of the laptop.
If I remember well, the KE9NS software creates the VAC1 by itself but there's no RX if VAC1 is unselected... (no matter the audio parameters I put)

Yes i would turn off vac1 and move the squelch to 0 till you get it figured out.

I think there's no RX at all if I unselect VAC1. (no matter what's in Setup>Audio)
And on the pic, the squelch is at -92 but I put it at the lowest (-160 I think) maybe 1 minute before...
Meaning it changes on its own...

Ben just a thought have you went to the flex radio site and downloaded the usb driver there and installed that one? Of course you would have to uninstall the current one, but im thinking maybe your issues are with the installed usb driver for the 1500 or if you have a laptop with win 7 or win xp to try it with installing the usb flex site driver there, i just dont have much confidence in win 10 when it comes to sdr via computer. Just some thoughts.

After all the 1500 came out with usb 1.1 initially and flex has stopped supporting the operating system drivers for xp now.

I previously downloaded the driver on Flex site but I'm pretty sure I didn't use it...
I'm using a Win10 laptop and once PowerSDR installed and Flex running, everything (supposedly) goes on it own...
Via the usb cable, the audio is coming out, the frequencies/bands can be changed using the mouse, etc... so the usb cable is "alive".   :-)
Everything seems to be working when using RVRX port so... but still, I can try...

Ok then your USB connection is all ok
make sure you powered speakers are in the correct jack
and check the mixer settings in the mixer tab at the top

Hi Bill, yes, usb should be ok.

In "MIxer", there's not much to change.
And on PA port, waterfall is fully black (means empty except interference) so the audio isn't faulty, is it?

What I am not clear about is...
Is the radio starting so you have a panadapter screen, you see signals? if you do then you can rule out an USB problem.The PSDR will not even load if there is a USB problem.
Is there any audio in headphones?
And is the settings ok in the mixer tab?

Yes, audio in speakers/headphones but only interference/static.
(with antenna on PA port)

I think as Tim mention you likely have hardware problem. once you connect your antenna to the antenna port there really is nothing to configure. It is not likely to be serviced in the field.

Ben here is an article indicating some win 10 updates cause problems with the usb driver and tells how to correct it by removing and reinstalling the usb driver in win 10 step by step ... hope some of the info i posted today helps out. good luck.

Do you know/remember if it concerns people who have no link at all between the Flex and the computer?

Ben, what is the latest problem your having at this time..
Do you have PSDR running with everything working but no audio?
Or no receive? nothing on the panadapter?

Let's summarize:

1) this is a second-hand Flex I just bought.
2)I tried using it with antenna on PA port (pretty logical) but never obtain OM signals but interference.
3) someone here told me to try RVXR port.
4) RX seems really ok on RVRX port.

Bill, the question concerns Wayne.   ;-)

I was wondering if the last picture concerns people having no communication at all between the Flex and the computer? Which isn't my case.

If you're receiving on the XVTR port, it would seem to me that the most likely causes of your problem are either a failure of the protection diode, as mentioned earlier, or perhaps even more likely, a simple mechanical failure of the primary antenna jack or it's connection to the PC board.  Have you not opened the radio to check for that?

Hello Rick,
I think you're right, it can also be a mechanical problem.
Haven't checked that yet, you all gave me to much ideas about the possible problem :-) I'll try to give a look to it tonight...

A few pictures.

And I've been told not to use VAC but if I do so, this is impossible to have audio. Panadapter and waterfall seem to be ok but no sound at all in the speakers/headphones. (I didn't think to try to plug the headphones right on the Flex)


And this is now obvious that when I put the antenna on PA port, it's just like there is no antenna at all.
So, next step is to open the Flex so that I can see (if possible) if it comes from a mechanical problem. (coaxial cable or so)
But still, I find some weird things with the configuration, no?

Hello there,

what do you think of this? Almost nothing in Setup>Audio>Primary...


There are more tabs in the user manual. (even if it's the 2.0 version in the manual)



And I indeed have audio (using the Flex jack) if I unchecked VAC but the sound quality seems to me pretty poor... (was better the day before as I was using the PC jack with VAC on)

Continue to use the the power speaker jack on the Flex and stop using VAC.
The reason for poor audio will be another setting or two.
It sounds like you are fixed up mostly.

Perhaps set your RX filter to low cut 50

Hello Bill,

Pretty fixed? Humm.. don't think so... Basically, my problem is the PA port...    :-)

When you're talking about RX filter, to me, it refers to the presets on the main window on the right. Right? On the last pic, 2,7k is selected. Should it be changed?

Thx

And one more thing.
When running PowerSDR for the first time of the day, all parameters are wrong. So, I change the port to XVRX (else there's no RX), a few colors, I put the world map in the background, the full window scree shot, etc... and if I quit the software and rerun it, parameters are wrong once again.

But the most interesting is now... if I "Export Database", quit the software and "Import Database", parameters are still wrong!        (smiley crying) + (smiley hanging)

There will be times when you run the software and it will not work. This happens for one reason or another. Shut it down and cycle power to the rig. Sometimes it requires a reboot of the computer to solve it. This is normal.

I can't ever having trouble wit PSDR in this way, the pesistance has been great. It sounds like you may need to re install PSDR. I know you probably have done that,,but may do it again. Something is not working right. All settings should remember

Hi Bill,
KE9NS version is always starting with  "wrong" parameters in the software.
I'll try with the 2.7.2 official version to check if, when I rerun it,  I can find back the parameters I just changed or not...

Ben in the pictures you posted show you have an unsupported sound card selected this is causing your audio issues. Many have the issue with win 10 with sound card drivers.

Wayne,
the 2nd picture (Unsupported card) was coming from the manual.
I posted it to compare with my Setup>Audio>Primary (1st pic)
