What's new Marty ? Remi - F1MQJ

Sarma surely responds. The reverse protection diode has been shown in the ubitx sch , both v3 and v4 perhaps. I would only suggest that let us have a fuse in series to dc of say 5 amps. the reverse

"Without adding other relays like omrI on g5 g6 and alike, maybe some might prefer just connect the outputs of the four filters to separate antenna outputs, one for each filter. Isn't more simple?

The filter components as designed are perfectly adequate once the relay and layout problems are addressed. Yes, there are likely improvements that can be made with optimization but they are fine as

Unfortunately, I did not make it clear about the DC power source fusing on the early wire-up version I gave Patrick for his stock Wiki. My assumption was that DC power source fusing would be ahead of

iz oos.. re getting cores etc at a reas price an inspiration that might benefit me as I get to find out of this Indian is reliable. First go to

Thanks Raj but no, Glenn is not in the Spam folder. Bill, VK7MX

Thanks Allison for the feedback. The core I have used must be lossy for conventional transformers. I have just wired a 1:49 transformer using a small binocular core with 8uH at the input and 380uH at

Check your SPAM folder and if they are there mark as not spam. I use a prefilter called Mailwasher and I have groups.io domain tofriends list.

Hi Tom , The uBITX_Manager is OK on my Linux Mint with Mono. I sent a message to Nextion and they answered ..... Posted on: 07-08-2018, 03:35 by Nikos I would like to ask you how I can install

Jonathan I will add PH2LB's reverse voltage protection solution to that page at your suggestion. I hadn't noticed that idea previously, but did recognise the distinctive build

Can anybody explain why I am not receiving Glenn's posts on this subject but I am receiving the responses he receives, such as this from Colin. Yet, if I go to the group

..WARNING WArning.re chip subs for audio ref Eddie E - the TDA 7052AT is what Leon used. the A and non A suffix versions are different in volume control area. Stick with Leon's AGC concept if you go

Eddie E Lucky day with the socket the TDA7052 is your friend AGC is built in . I believe Futurlec.com may still sell it if so it will be just pennies and F does not have any MOQ as far as I know.

Without adding other relays like omron g5 g6 and alike, maybe some might prefer just connect the outputs of the four filters to separate antenna outputs, one for each filter. Isn't more simple? Would

Hi Nikos, I downloaded the Nextion editor and tried to run it under Wine on my Mac. The first screen came up, but then it died. The console had lists of things it looked like it could not find. I'm

That is excellent Glenn, I never ceased to be amazed by this group. Colin – M5FRA

before you rush in with the Tx Rx relay which does a lot of work sugggest you look at this How and Why to Use PIN Diodes for RF Switching | DigiKey‎ Adwww.digikey.co.nz/‎ the URL is humungous

I wonder what the spurious emissions were like on this! The ARRL owns a spark gap transmitter that is housed in W1AW for what it is worth. They dont use it, though I think the time I was there they

Belay all that .. Japanese LPF cct sent to the VK who is designing a replacement board. It gets 5 bands out of three signals ie 00 is also interpreted as a command. as usual old Timmo Fidler went off
