I use an innova 3320 dvm; it showed up in an issue in QST some months back. Its good for what it does. 73, Kelly K5AID

Did you use 1 watt resistors or higher? I am assuming qrp levels similar to our ubitx, of course.. 73, Kelly K5AID

I am with Robert, a decent dvm is the first cab off the rank.? I sold my oscilloscope on ebay as I found that while useful when needed, it wasn't needed very often and a digital one could do the job.

Hi everyone. Thanks for the interest. I will put all of you that have responded and emailed me at the top of the list... I will try to get this done ASAP, but I have very little time lately with work

I attribute it to my assumptions, obviously. I was shocked myself after all the positive remarks, etc. I am glad it works as I was wanting to experiment with it, like make a receiver for my dad, who

Do you happen to have a source/part number for the heat sink? Thanks. Bill KC1JTS

That's interesting, i have based 5 different VFO's off of the schematic Rich provided on his Blog and all of them worked perfect. I have a DSB radio I designed around this VFO and use it all the time.

10dB sounds a little more reasonable for measuring RF. I made up a batch of PI network attenuators for 3, 6, 10, and 12dB.

Richard, thanks for reminding me abiut the attenuator. You sure thats enough? I was figuring 10dB. According to the Resistor tables for a Pi it seems easier. Just my own opinion... 73, Kelly K5AID

Thought I needed a break so I thought I would make an AD7 C vfo since I already had an AD 9850. Well shame on me for trusting a schematic.? I seriously built this twice, on perfboard and ... after i

Thanks, everyone - based on Curt's comment, there may be nothing to adjust - I'm just not picking anyone up / trees in the way / bad weather / bad timing whatever. I base this on the fact that AM

Not aware of any digital mode using LSB. 7.074 USB is FT8, 7.076 USB is JT65.

Curious, I did see the photo in the group website. Looks like it has since been deleted. Jerry

Arv, I don't look at the group on the web unless I'm searching for something. The pic came as an email attachment. Vince. -- K8ZW http://www.metalworkingfun.com http://www.hamradio.fun

It's very tough, to protect a radio installation from a direct lightning strike But it's well worth protecting your gear from high voltage electric fields. Just the wind blowing on an antenna wire can

Hello Nick, I know you haven’t given the signal yet that the time window for ordering your board is opened. But I don’t want to be the one missing this opportunity because of a too late a

Are you sure that's not just local AM stations? My uBitx was completely unusable at first - all bands, all frequencies, all i heard was the 50KW KOA "blowtorch". More sane AM signals will definitely

Craig overall its a different sounding receiver - without AGC there is minimal (but enough) gain available. based upon your description - I wonder if the BFO adjustment is way off.? Before concluding

Ok, back to it finally - tiny bit of new input: Was able to tune in a local AM station - sounds decent - tuned BFO with that, for better or for worse, but in the end, it was already ALMOST ok, and now
