I had an old Panasonic DS2E relay. Here are top and side exploded photos. Sorry for lack of clarity The contacts can be seen mounted on either side of the relay. The armature moves sideways pulling

Has anyone tried changing the attenuator from 6db to a 3db one? 73 NIck VK4PP

Mike AI4NS What is this "2-factor authentication with Google" that you mentioned? I just looked at your member profile on the BITX20 site and see nothing like that on Groups.io. You are set for All

I was using 2 factor authentication with Google. It is still set for my groups.io account, and I need to get it turned off. How do I contact a group admin or someone that can help fix my account? Mike

There were a bunch of spurs coming out of that first mixer into the 30mhz LPF on transmit that were below 30mhz. One in particular (first flagged by Allison) was at? (45mhz - Carrier), so

OK, 3 more plots.? Mouser just delivered. The first one is with 680uH and the second is with 1mH. That's about 8dB better at 25MHz and below when compared to a plain uBITX "16 pin" relay. The third

Thanks Jim that helps. I may have been a bit optimistic about the test lead situation here.73 Scott

Allison, concerning the "stuff" coming out of the first mixer passing through the input lpf and reaching Q90: this gives me the hint that the lpf does not problerly do what it should! Did You make a

Henning, If you use Q90 you only need maybe 13-15db with headroom. I'll make a comment.? BANDPASS the output of Q90, there is way too much stuff coming out that can even if it meets -43dbc down

I gave phone/SSB a go last sunday from Northern Virginia, no luck. I have much better luck with PSK31 or JT8.? Does any uBITXer want to try digital modes on 10/15?? If so, I'd vote for staying on

Thanks, Allison. Jack, W8TEE

Allison, This is a plot with a 680nH inductor in series with one side of the coil and relay armature. Note the self resonance is now off to the right beyond the 100Mhz scan width and that the plot is

Allison, I totally agree,? my post was just thinking for the stage after Q90 or its better verison. My guess is that the BFR90 or as You already mentioned these small signal transitors are not good

timmy, Your not even close.? The Funster (a CW rig) topology is to drive a class C final for CW so linearity is not even considered.? So that is outside the conversation as usual. The drive needed
