I was searching for Hammarlund HQ-100 wisdom when Google pointed me to the Electric Radio articles of Janis AB2RA. They were in ER #380 and #381 (February and March 2021). Lots of good stuff in there. <\/b><\/div>\n

This morning I happened upon a 2014 SolderSmoke blog post (as you do) about my Tuna Tin 2. Turns out that Janis was my first contact with this rig. And she too was running a homebrew rig. TRGHS. <\/b><\/div>\n

I continue to work on my HQ-100. The AC hum is getting worse so I have ordered a replacement capacitor can from Hayseed Hamfest. But I was a bit confused about which cap to order. Hayseed has two caps listed for the HQ-100 — one (it seems) for the early model of this receiver and one for later models. Is that right? Did Hammarlund update the power supply to add filter capacitors? Take a look: <\/b><\/div>\n

Dean KK4DAS is getting ready to work on his dad’s HQ-170A. He too will find lots of wisdom and tribal knowledge on Janis’s wonderful web site. <\/b><\/p>\n

Her main page: http:\/\/www.wireless-girl.com\/<\/a> (with a vast amount of technical info available through the links on the upper left side of this page) <\/b><\/p>\n

Thanks Janis!<\/b> <\/p>\n
