I am scratching my head wondering whether any of this applies to the LP-PAN, or whether it is only relevant to other panadaptors such as the Softrock and the Z90.
K8ZOA's web page (the same one everyone is quoting) says: "I looked at two potential panadapters; a Softrock and my Z90. (Telepostinc's LP-PAN has a built-in amplifier to overcome the transfer gain problem.)" and in the recommendations near the bottom of the page, refering to the mod, "These steps are not necessary with an LP-PAN panadapter as it has a built-in isolation amplifier." That same web page also suggests that an alternative to the mod would be to use an external buffer amplifier. So, I have two questions: 1. Is the mod necessary with the LP-PAN, or is it only needed with other panadapters? That is, is the noise figure of the LP-PAN's internal amplifier sufficient, or is the mod to the K3 required to lift weak signals above the noise floor of the LP-PAN? 2. Would the external buffer amplifier solution be a viable alternative to the mod? 73, Rich VE3KI _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
