OK gang I want to try to run the PA off 24 volts. Any suggestions as to size or type of heatsink. Do I have to re-adjust the bias, etc? I was wondering if anyone has used a 7812 to regulate power to

Thanks Dex Looks easy enough. That's what I love about this radio, it's inexpensive enough that you don't mind experimenting. I built the anti chunk circuit shown elsewhere here, that uses a 2n3906 to

I got my Bitx40 kit in the 10 days from India to the Caribbean, got it a couple days ago. Need to assess which housing to use b4 building -- AncelB, MIT EE6002

You will get a shipping confirmation from DHL takes a couple of weeks for that to show up in your email. I paid with Paypal <gpodave@...> wrote:

No, Brent, no AGC yet (no Raduino yet- it's en route), but Yes - lift R111(restores proper power switching to Q16) and 1N400x +12 (nearest I found was at R101, nearer end) to U1 pin 6. No ill effects

I agree Mac, I usually expect a couple of days before anything ships and then the shipping time in addition to that. So I really have no worries with this order.? Glad to see Dave got some info on

I think,there is no serious problem. 29-1st oct it was weekend. Somebody has to check order, pack TRX, send it. It is nor a big proffesional shop neither factory. Sometimes there is no "one day -

Pat,? thanks.? Good to know I'm not the only one (sorry that's at your expense :-).? If that's the case fine.? I know that this is a hobby and a very good price so an 'out of office' reply would

I don't know that it's normal, but you're not alone. I placed my order on 1 October and haven't heard anything yet either. No additional info in my paypal transaction either.? Perhaps someone was

Brent, thanks for taking the time to reply.? That gives me some useful info - nothing in the paypal records however. 73 Dave, G8XUL

Should be power connection.? Arrrr, I hate how unnoticed auto correct makes me look illiterate.

Hi Dave Not sure what the story is. When I ordered, I don't remember if I received an email from hf sigs. I believe I went back in to my PayPal account the next day, and hfsigs had added the shipping

Hi Dex I was thinking of it. It looks like the only real thing required would be to route a permanent power conception to the 386. Probably no more difficult than Allard's cw mod, which was no

Hello group, I ordered the Bitx 40 with DHL delivery on the 29th September from the RFSigs web page.? Other than the paypal receipt for the payment I've had no comms.? I've written

AFAIK, they are triac operated and run on AC. Designed for 250v AC and 2A If used for DC then probably it will latch up and not release (open)!

Brent, have you tried your mixing scheme on U1 perma-powered? or would that be too butcherous? Dex ZL2DEX

Thanks for the replies.?? I was going to wait until a connector arrived next week to test the mic but I think I will just lash the wires together over the weekend to see how it works.? I will post
