Thanks for your reply, Yeah I was afraid that would be the case.

Unfortunately almost all Japanese radios are set to conform to Japanese laws and are not modifiable to meet US US specifications. The Japanese "FCC" does not allow the radios modification and these

Hello all! I recently purchased the Japan version of the IC-7000 for use in my my shack while my other USA version one will stay as a mobile. Of course there are some difference in frequencies between

Forgive me if this has been mentioned before but as this is the 29th reply I haven't gone back and read everything. I always go first to where the effect of a fault is obvious without any ambiguity,

Thanks Tommy. much appreciated. I thought there was only one version in circulation. Anyway sounds like you have some good advice from members here . It does sound like RF power is being lost

James, The link to all the updates of the Ic7000 service manual is here: https://sfc03cda1ecec4dfa.jimcontent.com/download/version/1533230316/module/4802171362/name/IC-7000_SM_5.pdf They are all

Apply a DC via a resistor to JHFOR, see if the power folds back and current drops Then you can work on it and trace 73 Andrew ?Get BlueMail for Android ?

All well and good, but there must be an O/C some where in the TX path! Or a S/C cap 73 Andrew ?Get BlueMail for Android ?

Hi Tommy again, Also looking at the block diagram, I can see the TX and RX share the LPF, which actually turns out to be Band Pass filters!! Fairly wide. How does the RF get to the filter board is it

The power control will not reduce power if the forward power measurement circuit is not receiving power. As it is after the bandpass filters and that is where the problem seems to be. Currently the

Hi Tommy, Can you turn the power down on FM or CW to a few watts? This will help with signal tracing ?Get BlueMail for Android ?

Andrew Yes the current supply varies with usb modulation. That is why I put the mode to FM for the supply current test. The odd thing to me is that the supply current is substantially higher with the

Hi, You need to find out if there is RF power being generated.? The current is a clue, so switch to USB key up you should draw a few amps bias current, the speak CQCQ ect, the current should peak in

This sounds like the output gets may be damaged, remove the drive and see what the current is, should fall the biased only 73 Andrew ?Get BlueMail for Android ?

Hi you need to see if there is RF before the LPF area, how is the RF board connected to filter board look there. As you changed bands check the LPF relays' actually energised. RX received may be a red

Mike, Try this setup video on Youtube for the N1MM setup with an IC-7000. https://www.youtube.com/watch?v=RnYLuJB1dr0 He doesn't say which external device he is using to key N1MM (using the F-keys to

Thanks Tommy

I will try to send you a link tomorrow. There are 4 updates since the initial release. Two in 2008, 2009 and 2010. [email protected]> wrote:
