John, since you asked............. The 4x LPF Relay Filter board with plug-in LPFs (pictures further down on this thread) will fit in the same location as the existing 4 LPFs and the 4 associated

Hi John, I will let Kees answer for himself. I have a homemade steel box and my uBitX barely fits - like yours. It is a lot smaller that the few others I have seen. But..I suspect that I can find a

Yes, I have an order form on my blog. I will add the boards to it and let everyone know... 73

Kees, With what HFsignals used it would left to the transformer symmetry. The testing was part of the what int he world is going on after spurs were spotted. Allison

Allison, If the old reliable standby SBL-1 mixers didn't make any difference (thanks for testing), I would guess the HSMS-282R would not do any better, ......although I've had luck with the HP "die

Hello Nick, When the boards are received and you are ready to take orders how would you like to be compensated, PayPal. Thank you Ripley KD8UYQ The words are mine but this iPad does what it will with

Hello Kees, Will your proposed mods here change the case requirements for the uBitX.? I have a?Hammond 1402DV (

Your accomplishments are massive when viewed in one big list. Basically you have changed our little Chevy into a nice big Caddy! ? My little ubitx is making contacts with my mag loop INDOORS! Take a

As far as the firmware is concerned, for monoband operation you could use the latest Raduino sketch v1.28.1. This includes the latest enhancements such as spurious prevention, CW keyer, capacitive

How about replacing the 2N3904 in the Bi-di amp with BFR106? as with Q60 pre-driver? Would that help in making them more linear? 73 Nick VK4PP

HI Everyone, Boards should be around 2 weeks, i took the cheap option for shipping... 73 Nick

I just checked?https://github.com/gcallipo/Raduino_Multi/blob/master/src/raduino_multi_v1_0_1.ino? ? covers 80 40 20 15 10? so in fact the code is already there and supposedly tested and contains

Kees, The mixers are already using monolithic diode pairs.? Going to diode quads might help balance but I can say replacing the mixers with packaged Tuf-1 or SBL-1 made not one bit of difference.

It would be better to put all of this on the main board as close to its landed destination as possible. Just send the I2C to the main board. Sent: Wednesday, September 12, 2018 9:52 AM To:

Since homebuilt diode DBMs are quite "touchy" what about using a better matched diode ring quad mixer like the HSMS-282R.? Maybe this should be in the "spurs" thread 73 Kees K5BCQ

Does he have a true 3.5 version available for download? I notice the link has the tft only. Is the hmi available? -- N5KBP

Gordon, 1. ?Fixed external filters, changed manually (no software change) 2. ?Replace the right-hand side of the relays with a daughter board as I did. (no software change in the way I implemented

HI all, I've started on that in the wiki and its not a small task. Also some of the fixes are not "settled" with conflicting approaches. Right now the best and most complete is Ubitx.net. Allison

Farhan, Yes, Si5351 crosstalk may not be a problem worth chasing for most. Though a hack to the 6dB pads would be quite easy to do, if that does help. In addition to RX birdies, I can believe si5351
