I think part of the problem may be in the provided instructions, specifically this step: click add to map at the bottom of the box that pops up ...there is no "add to map", nor is there any box that

I would think it depends on its purpose -- is it made for feeding a mixer or feeding a mic amp? The one I was referring too was the one on his site that was available from the above link and was for

Hi, I would think it depends on its purpose -- is it made for feeding a mixer or feeding a mic amp? M

Looking at the schematic of the output combiner, are you really using 150 ohm resistors for a 50 ohm system? Every similar output combiner I have ever build for a 50 ohm system has 50 ohm

Are you sure your oscillascope is not on 10x vs 1x? It seems to be exactly 10 times down. Check some dc voltages with the scope and the bandwidth settings too.

Bit hard to tell from the photo, but is the transformer wired correctly? -- https://www.vk5tm.com

Hi Ashhar, At the oscillator emitter the voltage is 72mV peak-to-peak. At the amp collector it is about 9mV Both with a 49.9 ohm load. Something is quite wrong now, the max output is only 5mV at the

Arv, The current map is just a google my map with no functionality beyond what you see on the page.? If someone were inclined to develop an new site I think google does have an API for integrating

Chris It seems that there may be room for some modification of the BITXMAP software. If it were coupled to a remote receiver or one of the beacon receiver systems it might be possible to make BITXMAP

Elia, 40 mv is really low. Can you measure the rf voltage at oscillator emitter and collector of the amp? [email protected]> wrote:

I love seeing builds like this! Dave Richards, AA7EE, carries it to an art form (notice Han's BPF in the photo): A visit to his site is just plain enjoyable to me. Jack, W8TEE

Hi everyone, I started building the two tone rf generator from Farhan's www.vu2ese.com ( http://www.vu2ese.com ) site to add to my test equipment. I have finished the first section (ie oscillator #1)

Folks if you need help adding yourself to bitxmap.com ( http://bitxmap.com ) please just ask.? If you mess something up on the map please let me know so I can fix it.? I understand the format is not

I will take one jackal board,please send me the email address to send the PayPal $$ to. Thanks, George W5GRG

Ramón, te agradezco que lo detalles en espa?ol!!, ya te contaré como va quedando ya que lo pondré en práctica!, Saludos desde la Patagonia

There are two photos, one for each of the two signal sources as well as two spectra photos.? When I compare the two, the one from the Si5351 seems to have more steps and is more jagged than the one

Assuming I'm reading the scope photo correctly, it could be that bandwidth of the scope was set to 20mhz. With an 11mhz signal the scope would likely already rounding off a square wave signal. At

Here is what Jack posted: Unless Doug has some leftover stock, and I'm pretty sure he doesn't, QRPGuys is no longer selling the boards. Al and I do have some that we can sell for $25 which includes
