Only getting about 25 watts out or so on HF, VHF/UHF is fine, full power.....Its NOT the power cord, I've tried a couple different ones, same result, and those cords work fine with my 7300, I had a pr

Igor, Good job! Glad you were able to get the REF in spec with a simple change. Steve, W3AHL

I applied my TCXO mod above and it seems it works! I removed the R11 short and soldered in a 10k smd resistor at the pads of the not populated trimp pot. The 10k resistor is easily accessible now as i

Example: With R11 removed and the trimmpot soldered in (will be accessible from the top of the DDS board), for example 22k large, you may get following voltage ranges (the x-axis is the DAC output vol

On the DDS pcb - the position H10-V5 - you may find the pads for a smd pot trimmer (not populated), wired to the VC pin of the TCXO. They apparently planned to have a pot trim there in order to find a

Hi, as it has been discussed earlier I have been messing with the rather known potential issue - the TCXO's crystal aging. The service menu REF hex value of FF does not tune my 2LO to the required 124

Good evening to all.. finely i found the reason for no turning on of my 7000 R723 was broken..i measure 14v on the fuse site and only abbt 3v on the other side of the R. so to low voltage on the regul

Steve, when you change the tuning voltage wired to the VCTCXO the TX frequency (measured with a counter at the dummy load) has to change too, imho. The 7000's firmware or hardware has not got any inte

Igor, There is much that goes on in the firmware that makes it hard to predict how the hardware will work. But the behavior you see is normal. Setting the REF frequency accurately will either solve yo

I've asked Icom Europe on this (a week back), none answer yet. My gut feeling tells me the change of the maintenance mode REF setting from 0-FF must change the TX frequency in AM CW RTTY modes, provid

@Steve and Helmut: thanks for the hints. I started to doubt that I can see a change of the TX freq (while changing the hidden adjust hex value) after I had a look in the service manual - the "frequenc

I once had a 700 with exactly this problem. Cannot calibrate down, reaches 100 % in menu 51. What I found is the analog control voltage to the oscillator chip VFO was off and not in spec. Voltage comi

Using my calibrated Agilent 8924C analyzer I see OTH #51 vary by 1330 Hz from 0-100% when measuring the 124.032 MHz 2LO signal at P4. When transmitting on CW or AM at 20 MHz it varies 215 HZ from 0-10

Corrected: "With the OTH menu #51 I get about 150Hz diff from 0-100% (at 20MHz).

Hi, the same issue here. EU version, 13y old 7k. With the OTH menu #51 I get about 4.5kHz diff from 0-100%. "Luckily" at the 100% setting it is only 5Hz low (at around 20MHz). While messing with the R

Please re-read the question. Slightly different application, where two data ports may be involved.

Jeff, This is discussed in the ACLog documentation: https://www.n3fjp.com/cwschematic.html Robie - AJ4F

Using the 7000 with ACLog. Connected data port on rig to laptop with RigRunner. Works great to capture the frequency. How do I connect the rig to the laptop for ACLog to transmit CW please? Thanks!

Good job! It is important when handling all of the circuit boards to use proper ESD protection. I notice one picture of the LOGIC board laying on what appears to be a synthetic cloth surface. Unfiishe

Good job Steve, Now i can starting to control those things on my propre 7000 with the same problem... question...is there a posibility to test the rig without the pa board...to exclude problems in tha
