Re: How and where do i check the filters
Yes it goes into tx. believe it or not i can trigger a local repeater even with no output! Strange hey! I will look at the mainboard.

Re: How and where do i check the filters
Thanks for sharing your situation.? I looked at your info on QRZ and you have a nice station.? The IC-7000 isn't easy to troubleshoot! Your latest J101 IF measurements looks like the unit isn't

Re: How and where do i check the filters
The voltages are as follows: J101 Coax from Main IF !.840 cw 3.80mV 3.788 cw 3.20mV 7.100 cw 2.8mV 14.200 cw 3.4mV 28.400 cw 3.0mV 146.00 cw is 3.2 mV I think there is something wrongHere!

Re: How and where do i check the filters
Here's the manual for the probe that shipped with that model: https://beyondmeasure.rigoltech.com/acton/attachment/1579/f-06be/1/-/-/-/-/PVP2150%20User%27s%20Guide.pdf On page 4 is the parts list.?

Hi i am using a Rigol ds1104b with the probe hope that helps. i can see each ptest the voltage jumps!

Re: How and where do i check the filters
None of the voltages you measured are close to what I normally see.? The first set of levels from the IF should vary with frequency, but yours don't.? They look like just noise levels.? What

Re: How and where do i check the filters
Hi, did you test the transistors Or did you just change them hopping that this would work?, did you test for voltage supply on the transistors, Dave wrote:

How and where do i check the filters
Guys is there a way i can check the filters. My rig Rx just fine but now out put. 1) the main transistor has been replaced 2) the small transistrs have been replaced (for the transmition) 3) the rigs

Re: Compatible Tuner with IC 7000
i DON'T BELIEVE THAT THE ic-7000 is compatible with the ATAS (Yaesu). The Yaesu radios have a DC output voltage that changes level to drive up and down or stop. The SWR meter and control circuit in

Re: Loosing First LO when Changing Frequency
I think I have resolved the issue.? I noticed there was oscillation on the 3.3v line on the DDS.? I added a 10uf electrolytic cap to the 3R3V pad above DDS R9 and ground to stabilize the voltage.?
