Re: {Collins} Product Detectors



Deric,

Thanks! Found it. For some reason the Google search didn't return anything under "product detector R390". However, his url has changed. It's now www.electronicspecialtyproducts.com He has a new crystal controlled product detector for the 51J or R390 series. I guess one for a 455KHz IF and one for 500KHz IF. It's cheap enough I might try out one on other stuff...... I sent my friend the link. Once again, this listserve has been EXTREMELY HELPFUL!

I'm still in recovery mode from the contest this weekend. Lids shouldn't operate contests....

Michael,

There is one advertised in Electric RADIO EVERY Month by andElectronic Speciality Products: www.esplectronics.com and is available for both the R390 and R388/51JX series receivers.
Also Sherwood engineering has one available.

Hi All,

I just installed one of the Treetop product detectors into my 51J-4. For such a simple, cheap and easily reversible mod, it works just great. I think that a worthwhile change to it would be to add a slower release time constant for SSB and add a SSB/CW switch for fast/slow release.

My friend has an R390A that he wants to use with a product detector for CW. I remember seeing a commercial product which was sold on Ebay and also a website I think that was aimed at the R390. It was $99 I believe. My friend is interested in it, but I can't find it anywhere. Does anyone remember this product detector and who sold it?
