Guys thanks for the mention. I’ll get back to working on the LBSp1 over the Monday holiday. Rest of the week I will doing solo caregiver duties for my mom while the XYL will be attending to hers. I need to be like Pete and squeeze in those 15 minute sessions. My problem is it takes me 15 minutes to find my reading glasses!
To Hairy Potah’s Tin Whiskers and the Noxious Fumes of Fulgurating Rosins* *(unactivated, activated and/or patially activated [+/- Halogen Free!]) The insulation alters the capacitance at the surface of the amtenna wire which changes the velocity factor emough that the length requires adjustment. Or something like that. I think…. anyhow, it kinda sounds plausible
Bill and Pete What a coincidence; while listening to Pete suggesting that you should use an Arduino and stepper for your antenna tuner, I had a variable capacitor in one hand and a stepping motor in the other, trying to work out how to mate the two together to build my antenna tuner. Although making it fully automatic would probably be easier my intention is to have a remote link using an Arduino to control the position of the capacitor and switch the relays for the coil taps. 72 de Steve M0KOV
Is a new GQRP Circuit Handbook being published? The one here is from 74-82 https://ia601901.us.archive.org/19/items/G-qrpClub1983/G_QRP_Club_1983_fixed.pdf 73 Ed KC8SBV
Pete mentioned why use a LCD display. I have an answer. I use a lot of HB rigs outside, i.e. SOTA, picnics, just for fun. It is hard to beat an LCD display out in the direct sun. Often the places I go I have little to no shade, and the eyes are getting weaker. LCD works very well
Come on Bill, your Tuna tin Two transmitter is less than a watt, you been there and done that!!
Argh. Please sample down to mono.
