In an interview, https://www.youtube.com/watch?v=2_BPq5E5MlA ( https://www.youtube.com/watch?v=2_BPq5E5MlA )?(if you watch it, the audio connection DOES get better after a while), farhan said his

I have built a dozen boards lately with the SI5351 and a Tiny Crystal. Lots of problems. I made a way to test the parts before finishing the board. I install just the I2C parts and hook to another

sensitivity or not sensitivity..............How many don't have see that?https://www.youtube.com/watch?v=q2v4Q69bs8g 73 de Giovanni (i7iwn) ----Messaggio originale---- Da: "Michael Hagen"

Adrian, I use extra strong glasses and lots of light. I flux the area and use a tweezer to put in place and while holding the chip down i just tack one pin. I let it cool and solder the remaining

I looked too at the fishing poles. I would bet they are all of the same "crappyness". I doubt if any are much better than others? Maybe all made by the same Manf? I may find the Jack pole you

If you got real 50 Ohms, the Attenuator is usually 50 Ohms in dB (Power). You can calculated it. But you have to know what is coming out of the generator. You can convert between power and uV with P =

Unfortunately the 7.2 meter is sold out. The next shorter one is 6.3 meters. There are others on eBay in the 7.2 meter length for $10-$12. Not sure of the quality though. I have the 31 foot Jackite

Ryan: Thanks for the post. Also, at the bottom of the antenna pole article is a link to BITX40: Is It A Good?Beginners HF?Radio. I also found it interesting as it shows what can be done with a

Adrian: SMD's aren't as bad as you might think. Try this: On one leg of U2's PCB pad, place the thinnest touch of solder you can ("tinning" the pad). Using bent-tip tweezers (I bought one like

That looks very good you have done a first class job

Do you remember what model that one is? 1120 perhaps? Thanks! Vince. -- Michigan VHF Corp. http://www.nobucks.net/ http://www.CDupe.com/ http://www.metalworkingfun.com

Hi the links you posted are not working I would like to see one for 60m and 80 I am sorted for lpf for 80m / 60m

Use a step or a bunch of fixed attenuators. 2mv is -41dbm. Raj and I were still hearing our generators at -130 (which is 0.07uv). See if you can find 3 30db fixed attenuators and you'll be good. Then

Thank you for the info. Keep up the good work I'll build one for mine 73 John Sent from my iPhone

But... If I use an attenuator that is "analog"... How am I going to know the amount of microvolts that I am iinjecting into the BITX?

That one is still going to require attenuation. The lowest it puts out is 2mv and you're going to need .1uv or less for sensitivity measurements. Vince. -- Michigan VHF Corp. http://www.nobucks.net/

I hope mine are not fakes I have had the parts over 2 years

Ryan, IRF510 like devices as we get from International rectifiers are fine. Many others make IRF510, like VISHAY, Fairchild, ONsemi, many, many. I do agree that buying 10cents IRF and expecting

It is perfectly possible. I have an mdt on a Peli Case and it is very sturdy. The difficulty is to cut it tight enough in order to get a perfect size

I wish I had read this before. I reciently purchased 5 IRF510 from Ebay.?I assume they are bad boys
