Sean, RJ, At the risk of repeating myself, please investigate the recent ARRL Antenna book. Information regarding Yaggi design and construction abounds. There is a bonus CD with a great deal of useful

Mike an All, Kudos to Mike for finding a scheme to get the desired measurement results ! Yet another issue with measurement challenges is ... Is the measurement weighted, and if so, does the published

For those of you wishing to try something different, think about spectral analysis as opposed to the usual and customary THD meter. Benchmark the signal source and then subtract the individual source

Mike, That need was recognized by former HP employees when Sound Technology was formed. The result was the 1000 , and later, the 1020. Sadly, as broadcast radio seemingly devolves to an IP stream , th

Ron, Check out the GeneSic app note AN1001. Sic rectifiers are a mature technology now and the issue you mentioned applied to first gen Sic parts. That was many years ago. HRW

Glenn, Based upon what I've read, the Sic devices are likely going to be found in every power manipulation device in the coming years. The prices are way down, there are many more device options now,

Bob, Wow , I guess the Sic parts have become popular. I still have a few of that item that I paid almost 4 $ a pop for. But that was a while ago. They really are a better device . I'm not so sure if m

Rick, Yes, for the first year or so, I only used the low current Cree 1200v Sic rectifiers. After all, with the typical can caps and supply voltages found in a tuner or preamp, the higher spec devices

Series resistance added to a silicon rectifier diode is required to avoid changing the stage operating points when replacing selenium rectifiers. A selenium rectifier typically has 20 to 30 volts of f

Yo Geezer, I feel your pain. That is indeed an odd one. Have you thought about drilling out the rivets and installing a IEC power recepticle ? HRW

To all, Now that the power and internet has been restored to my neighborhood ( 6 days out ) in SW Ct after the latest atmospheric disturbance, I wanted to offer my two cents worth re listening to radi

I have to admit that as an early adopter of the Sonos system, and having installed many Sonos systems in SW CT , having a decent FM receiver seems less desirable these days. Still, as a radio enthusia

Bob raises an important point I forgot to mention. A Vertical stick ( ST-2 ) is a 360 degree pick up pattern , that being , it receives FM stations AND lots of multipath. Conversely , the “ T “ dipole

I also looked into a Ron Smith antenna. The dimensional weight shipping from the UK is a big turn off. So here is a suggestion for you guys with attic space or a beefy chimney with HD chimney mounts.

Victor, One of my collector customers buys lots of tuners from a guy in Germany. Perhaps he can help. What I can tell you is this your best bet is to speak to longtime owners of Hi Fi stores in your a

As I have said before, that was me a long time ago. PG, review your forum email, I have shared my 3001 experience with the forum and you previously. FYI the current flat rate at the Soundsmith for the

No, I didn't get it from AAS, I did all of AAS high end tuners up until about 5 years ago. I'm the Tandberg tech that had a relationship with TOA until they closed in Armonk NY , and then I serviced a

R Kent Brown, Basically you have two options as I see it. A vertical Omni such as the Magnum Dynalabs ST-2, and the small Yaggi made by Stellar Labs , and sold by a number of venders. The Yaggi is pre

To All, W2aew on You Tube has a useful video on the use of sweep generators. It is video #45... check it out. HRW

Mike, In the Carr book, there is a interesting way of doing this. A variable output 10.7mhz crystal controlled source having a wide range output attenuator, is mixed with the output of a sweep generat
