Hi Gordon I already bought K5BCQ PCBs and they have arrived. Can you explain to me how to get them in China? Thanks for your help. 73 QRO Gilles F1BFU / FR 2018-09-11 20:08 GMT+02:00 Gordon Gibby

Hi Gilles— I don’t really know how to ship to France...and I suspect it would be cheaper for you to get them directly from China. Do you need help ordering from pcbway.com<http://pcbway.com>? You

Look, i have find this now and i don't know is this right or wrong when look at the ubitx v3 shematic i can't even find this as a shorted circuit only crossing line in shematic.. so please help me! Is

I just experimented with the ClockBuilder Pro software. It does not like the SI5351 with 3 outputs and provides warnings under all conditions that I tested. I tried everything I could think of. I

Hi Gordon Is possible to send me a PCB in France ? 73 Gilles F1BFU/fr 2018-09-11 14:38 GMT+02:00 Gordon Gibby <ggibby@...>:

Wow!!!? ?Looks like 21 of the 25 boards? have already sold in about 4-1/2 hours since I put up the ebay --- I expect I'll be able to mail all of those out tomorrow as I have a day off from

ClockBuilder assumes you are using the si5351 to replace fixed oscillators. Our vfo at clk2 has to operate continuously over a 30mhz range, you can't run ClockBuilder every time you twiddle the tuning

Hi, Not sure if this will help or not, but just saw this on the SILabs forum posted by an employee:

I heard earlier and confirmed today that si labs had given certain recommendations regarding crosstalk on si5351a chip here is the link to the related page,. Hope it serves our cause too.

Hello Gordon, Order placed. Thank you sir for taking on this project. Ripley Sent from Mail for Windows 10 Sent: Tuesday, September 11, 2018 8:38 AM To: [email protected] Subject: Re: [BITX20]

Carl, I would think so.???#58782 ( /g/BITX20/message/58782 ) One VDDO pad per clock out should be much better than 3 clocks sharing the same power pad. Also the?QFN? package has

RCboatguy, The problem may not be the supply line but the ground line and even if there are more? its still current flowing on internal ground buses and the bulk silicon. The only way to know is

I am wondering if we could use the 8-output version of the Si5351 instead of the 3-output version to reduce the cross-talk.? The 8-output version has separate Vddox inputs per pair of clock outputs

AVAILABLE AGAIN! Found the package of boards sitting on a neighbor's doorstep. Hooray! Managed to get the listing re-activated (eBay isn't that easy to figure out....but I got it).

Raj The green display line is set at -43 dBc for a 33 dBm carrier level. None of the harmonics comes close to that level. The harmonics are higher than I would like but certainly acceptable. The test

All three with the 74AUP wich are one inverter per package. I didn't try the hex inverter part (6 inverters per package).? I suspect that needs testing? as you run into the same issues of common

Looks pretty good. I see unacceptable level 3rd harmonics below 18MHz. Raj

My LPF boards are in, I'll post them to testers asap. I'll also order some 45mhz filter boards too... 73 Nick VK4PP

Hi Raj As requested. Conditions: - 30 mVrms 1 KHz audio input - Power Out set to nominal +31 dBm which reads as 2 watts on my meter; set with RV1 - On board filter bypassed; external LPFs used as

perhaps you can replace either, arduino nano, interface if any to si5351 or si5351 itself. please see some videos. it is easy . with little effort you may also be able to load the firmware. If you
