Yes, aiming for the 6.2 - 6.3 range. With 21 turns for L2 it was a little high, peaking in the 6.4 region so I tried 23 turns which brought it down to 5.8, so I've settled on 22 turns for the moment which seems about right with the ability to squeeze or open the coil a little.
I did see that you had used the Wondom board, they seem to be pure unobtainium in the UK, I have accounts with Farnell and their sibling CPC and they don't have them.
I'll trawl AliExpress and Banggood to see what they have.
I have tried a clone 100w mono board from eBay also based on the TPA3116 but no joy at all. I'll give it another go this weekend when I have some more time.
FCC PROPOSES FIRST PIRATE ACT FINES TOTALING MORE
THAN $2 MILLION FOR ILLEGAL RADIO BROADCASTING
7. On April 8, 2022, just over two weeks after the Agent issued the third NOUO, Barnes
uploaded a video to his public Facebook account stating that he was again operating his pirate station.22
Barnes stated in this video that he did not think the Commission could stop his unauthorized broadcasts
unless it “locked him up.” On April 14, 2022, Barnes posted yet another video stating that he was
“getting ready to go live on 100.5 FM.”23 After conducting additional research, the Agent also discovered
that, in the year prior to the start of the 2022 investigation, Barnes had uploaded over 30 videos to his
public Facebook account in which he stated that he was the “Eastern Oregon Pirate of Pirate Radio
Eastern Oregon” and that he was broadcasting live or was planning to broadcast live on 100.5 FM in La
Grande, Oregon.24
This decoder improves the stability of the reception, because it partially eliminates the effect of selective fading of the AM carrier wave.
Yep, I uderstand all that. But often, to escape the splashes, I have to go to USB or LSB.
I even use SAM with the sideband selection, SAU or SAL. Alas, in those modes, all too often, the sync is lost, and the audio is mashed. And when I see a carrier on the waterfall, I can't tell its exact frequency, I point on it, and the software tunes 1.5 kHz aside ! Then I have to make the panel come back, but it covers about 40 percent of the waterfall range on my small screen !
The way I avoid that is by tuning in AM mode then switching to the one I am going to listen in.
When using the pointer on WF to change frequency,
if the mode is USB or LSB,
then the soft tunes aside, 1.5 kHz away from the pointed frequency, grrrrr....
As a licensed amateur who enjoys listening to all types of communications I've often wondered if it was possible to use HF amateur bands to share real time spotting information about whatever it is we happen to be hearing. (broadcast, pirate, utility, beacons, etc.)
It says very little. ... Tell us exactly which policies and how they affected you.
My first build attempt at the U-LULU, with a board made by JLCPCB using CDS's gerber files.
Learning how to solder all over again with a hot-air rework pencil, great for the chip but how do I stop the tiny caps flying away
On a test-jig I'm getting about 15w carrier, still more work to getting the output coil right and finding a suitable modulator. Any ideas on something still available from China in 2023?
I saw your DM too and you've obviously figured out posting photos on HFU and you have an additional 5 Watts since that DM so all is good.
