Been looking around for the 1210 680nh inductors?and cannot find a source yet. I noticed some suppliers only sell in very large quantities like 2000. So has anyone found a source yet or if so would

Top IMO. Bottom actually degraded things on MY board. Probably need a few more people to test tis before a cull consensus can be reached. Jim

So, is the relay mod a sure thing? I have put off ordering the relays until somebody says it definitely works. I jumped on the 45Mhz filter bandwagon and have them all installed and working on two

With two simple new fixes available to address the spectral purity issues associated with the uBITx, I have been busy updating the www.ubitx.net website this morning.? This includes an update to the

Jim Would you be able to take a photo of a uBITx with the new Axicom relays in place?? It would be nice to be able to show this on ubitx.net.?? I have ordered relays from Hong Kong, but they will

Jim: I have built everything in my shack including an Elecraft K2 (I was a beta tester for the 100-watt linear amp), auto-tuner, and other smaller projects. So, I am fairly comfortable, but putting

Hi Peter, Our radio club are so impressed we have 12 members who are going to build the the uBITZ using the through hole system. I'm sourcing components and PCB's using the gerber files. However the

Solder braid or a precision vacuum desoldering tool should be used IMO. If you have a Hakko or Pace desoldering station with heated tip vacuum tool this is best. I have a powerful spring loaded

So a rework station like the one in the picture should be avoided for removing the relays, right? <https://www.arrow.com/en/products/v23105a5403a201/te-connectivity> will get you the relays at the

I've never taken apart one of the relays that the uBitx comes with. But might be possible to grind off the plastic cover with a dremel tool first, then pluck the pins out one at a time with a needle

https://www.arrow.com/en/products/v23105a5403a201/te-connectivity will get you the relays at the cheapest price in the USA that I know of They even have free overnight shipping. NO absolutely do NOT

Jim: What are the actual part numbers of the Axion relays and where are you ordering them from? Did you need to use a PCB oven to remove the relays? What was your technique? I’m sorry if these

In post? ? ?/g/BITX20/message/60519 Lawrence Galea pointed out a Hong Kong source for Axicom relays at $0.98 USD for quantity 1, $0.60 USD for quantity 1000.? If those are

I have another V4 board that I'm going to build up, but I'm waiting on a special 3.2" Color TFT touch screen display (NOT a Nextion) for use with the Trimuvirate Skonk Worx "BITeensio" controller

Great find, Sarma, as the *world* continues to look into this problem. I'll run a test later today with the 1mH inductor isolation of the relay coils and then see the effect of adding a 10nF capacitor

Good Morning Jim, Thanks for entertaining the idea.? Your shared data maybe useful as you have shown same board and relay with different measured results. For that particular board and the

Thanks for those pictures, Sarma. To me, that seems to indicate even closer coupling from the relay armature to the coil. Bad for RF. 73 Kees K5BCQ

This is a cool find. Nice read.

Sorry Owen, Missed your reply. I put the inductors in a convenient place without obliterating the component legends. The seller on eBay had mentioned that they were Murata, the size may be 1210,

I'd like to second this question about the required inductors. Is it that the SMD inductors have a lower Q, or is it the smaller physical size, or the change in position, or a combination of all these
