ts-950sd audio loss

Hi Ernie Have you tried adjusting RF Gain control.Full CCW reduces audio output & increases meter reading & vice versa.Intermitent or no change could be caused by dirty or defective control pot.Good place to start. 73 and happy hunting Paul KB3LMV

UHF+ Ant Analyzer

Hi Mark Anritsu Sitemaster S 311 D has a range of 25-1600 Mhz, i suspect its quite pricey though.Saw a homebrew unit that N9ZIA built from a UHF VCR tuner that tops out at 900 Mhz. Here's a link(qsl.net/N9ZIA/wireless/antenna-analyzer-pictures.html). 73 & Happy Homebrewing Paul KB3LMV

Freq shift

Hi Glenn I'm no expert on FT 736 but it almost sounds like a Cap breakdown is causing your 35 KC freq drop or a cold solder joint,as it only occurs in UHF modeIt might be worth a call to Yaesu tech support in LA and pick theit brains. Good Luck & 73 4 Now Paul KB3LMV
