Hi Andrea,

These are good whips. I’ve purchased four of them for my experimental antenna designs. I dealt with the M10 mounts by just buying some compatible hex nuts. I paid $11 USD each plus shipping. Took a few weeks to arrive but it was worth it for the price point and quality.

This is a good place to get a fairly priced choke core and they have some good info:

I was banned because I included a link to the 'TOADS' discourse concerning an X6100 problem someone was having. The moderator seems to be a bit over the top to say the least.?

They sent me a replacement x-6100 due to other issues after firmware update and the new one does not get hot at all.I have several other Ham radios but really love this one - easy to use, always on the living room side table (wired to and Chameleon EMCOMM3) and gets out well on 10W QRP.?

You poor guy. I wish you luck getting a replacement.?

Yea, John, I’m aware of this as I read this list, too.

Oleg responded a week or so ago to my original request that he post it the STL files for the base mount that he sent to this group. Oleg said he would. I’m just reminding him of that so he can tell us where he posts the STL files.

I build antennas like this. Having the 3D print file to use as needed is so much better than having to order a finished product from overseas. This is especially true when I want to do the build-out with different specifications.

This is why I sent my 2nd email..Oleg is busy doing great work on his firmware. It’s easy to forget doing something like preparing a zipped library and uploading it…especially if he wants to include terms for use.

Amazing thank you!!

I've also tried to join a few times and have been rejected every time.? Gave up and moved on.?

Fortunately this group has been wonderful!? :-)

Hi Oleg,

whenwillyiu post the STL files for this Vee Dipole mount?

thanks,

Yes, this is an old and known problem.

My friend purchased a X6100 and was over the other day demonstrating the radio. He mentioned some issues with poor transmit audio reports using the plug-in mic. I set up a local SDR receiver to listen to his audio and noticed a strong on-frequency signal on the spectrum window of the SDR receiver This occurs on all bands and all modes. The X6100 wasn't directly coupled to the receiver of course. The SDR receiver was connected to an antenna switch which has an isolation of about 50 dB. The X6100 was also connected to the same switch and switched to an outside antenna. The noted signal was significant.? I decided to measure the signal from the X6100? directly connected, using my spectrum analyzer. I found the signal which I suspect is Local oscillator leakage (LOL), to be -47dBm. If the attenuator is enabled, the signal drops to -67 dBm and even more if the preamp is enabled. I'm curious if anyone else has measured LOL on their X6100??

As you can imagine, a -43 dBm signal is an extremely high level signal. In close proximity to another receiver that could equate to S9+30dB level!?

If you don't have a spectrum analyzer, you can get a relative measurement by connecting the X6100 to one port of an antenna switch, another test receiver to the other port of the switch and a 50 ohm load to the common port of the antenna switch. Make sure the switch is selecting the X6100 to the 50 ohm load and make sure you don't transmit on the X6100. Then set both the test receiver and the X6100 on the same frequency. Make sure the Attenuator and preamp are disabled on the X6100 and both radios on the same mode. You can then tune the test receiver 1 KHz lower in frequency for USB or 1 KHz higher in frequency for LSB. Make sure the attenuator on the test receiver's is disabled also. Look at the S-meter on the test receiver. What do you see? Ideally, you should have both the X6100 and test receiver terminated in a 50 ohm load but this will provide some relative level.?

It is not uncommon to see LO Leakage on direct conversion receivers however, I think this the highest I've ever found. Curious what others are seeing...

I appreciate all the replies on this.? I have now received 3 rejection notices and have also given up.

Thank you for providing this. It should be a help for others and me. Merry Christmas and Happy New Year to your family and you.

Thank you...very helpful

It would work best near the transceiver in my opinion.

Sorry, I do not.
