Location of FH2 Ft101ZD MK3
|
If I recall correctly you take off the bottom cover and the bottom screen over the finals compartment. Trace the coax center line back from the PL259 jack an inch or two and you will see what looks like a glass fuse in a holder. That is the lamp fuse.? I’m away from my notes so doing this by memory and I could be wrong.? GL! 73 de Chuck, WS1L?

Anyway, it loads up good but no receive, checking out what others suggest.? Specifically where is the Lamp that is designated as FH2? Can someone describe accurately exactly where this lamp is located, or provide a picture? Please, this is the only thing I'm asking, I'm not looking for any other information, I've read all the online suggestions that I have found so far.? All I want to know is where is this Lamp? --

From the service manual -? "The RF input signal from the antenna is fed through antenna relay RL2, lamp fuse FH2, attenuator switch S2004 (located on the lever switch unit...)" So trace the line from the antenna connector to the relay.? One of the other relay connections will be to a small clip-in holder for this: It's a good bet that if the rig was turned on near another transmitter while it was being keyed that this has blown.? If your TX is good, the Calibration signal is over S9 but the receiver seems deaf, this is the most likely culprit.

That is where I've been looking, nothing that resembles a fuse or fuse holder in this tank cage that I see on the bottom.? There is a 3pos terminal strip mounted inside the back panel by the receive antenna jack with what looks like a diode/lamp on the bottom but one end goes to chassis ground so to me that isn't it.?? I do see what looks like a lamp but it's mounted outside the final cage near the transformer. The SO239 center goes directly to an inductor that is connected to the relay.? I need a picture...? I didn't buy this rig to work on it, I'm going to spend maybe another hour on this jewel then off to market she goes.... Looks great with rated power out. |

OK... How much do you want for it? On Tue, Jul 19, 2022 at 9:50 PM N0EE via <n0ee=[email protected]> wrote: Thanks for the reply.
