Selecting Icom 7000 Memory Channels
7
I'm able to stick the +- dup & fm tone in the memory of the A bank, then name it and save it and I can select a memory channel with the microphone. BUT... When I want to select different memory channels by depressing the PBT knob and rotating the inner knob, DEPRESSING THE PBT KNOB CHANGES THE MEMORY BANK. Am I missing a step? Gene - K7HPF

Once I get the FM freq, dup, & tone working (so I can connect with the repeater) I push "V menugrp" to exit the tone set mode. What are the next steps to program a memory channel? Gene, K7HPF

Noise Blanker
Hi All! I primarily use my IC-7000 for FT8 ops these days, where the latest "In Thing" is SuperFox mode. It's new, and we're all in the learning phase of figuring out how to get the best performance out of it. On the currently running DXPedition (N5J) I've been having some luck with improving my reception/decoding under some circumstances by turning on the Noise Blanker function and playing a bit with the controls - I suspect because the Noise Blanker is helping to squish some of my local QRN without messing with the received SuperFox waveform. However, I'd love to have a better understanding of what the Noise Blanker is actually doing, and how the NB Level and NB Width controls affect that. I'm guessing that NB is some kind of peak limiter designed to clip impulse noise (where the clipping level is controlled by NB Level?). But if so it's not obvious what NB Width would do...? (Aurally the effect of the two controls sound very similar to me). Also, is the Noise Blanker upstream of the Rx AGC? It seems like turning NB on boosts the received (good) signal a little (as seen on the waterfall) and I'm wondering whether that's because reducing the incoming noise upstream means the Rx AGC is backing off a little bit. Unfortunately my IC-7000 Instruction Manual hasn't been super helpful, other than to tell me that the NB Level control adjusts the noise blanker level and the NB Width control adjusts the noise blanker width... :-( TIA for any knowledge and advice!

Driver Board Replacement, adjustments required?
5
Hello All, I have a couple of 7ks. A newer one works perfectly, as far as I can tell. An older one has low output and the driver board is suspect. I intend to replace the driver board - new parts and board are on the way. My question: following the board installation, are the adjustments (as recommended by Icom) necessary or optional? A Service Bulletin of Feb/2010 outlines a multi step adjustment procedure requiring equipment I don’t have - that’s the reason for this question. I want to replace the board myself, I’m capable of doing that. But the adjustments I cannot do without purchasing equipment at expense. So, if the adjustments are necessary, then I might just as well replace the board and send it to Icom to do the adjustments… may be cheaper than buying new equipment. Any thoughts or advice from this group? Thank you for getting this far …. Dan. VE7CTN

(Almost) Dead IC-7000
3
Hello there! I have a 7k with the “click-click no power” problem. I’ve found a good start about it here: http://www.s21rc.net/?p=49 Tested for the C501 and C502 in the main panel board and I can say one of them is really shorted. Does anybody have or had this problem in the past, and was able to solve it? I’ll try to fix it myself, but I have some doubts about how to remove the main board. Can someone give me some tips on how to remove it, especially concerning to the flat cables? I have no Icom Maintenance around, so I’ll have to put my on hands into the game, so, any additional information will be welcomed. Thanks, in advance. 73 from Brazil. ------------------------------------- Edson Rocha, PU2REO eirocha@... -------------------------------------

AGC Fault?
2
G'day.... I have an IC7000 on the bench that has me stumped for an answer for a few months now, it came to me from a friend and the driver had burnt up with the owner noting that it had odd audio and the power meter would go up on SSB with no audio applied so I suspected RF getting back into the unit being the cause of the failure. I checked the driver model and it was the later type so I ordered one and replaced it. All checked ok after repair and it transmitted fine but after a few days the meter issue and bad audio returned, I put the unit on the bench, on a dummy load, no mic, just a switch and the fault persists, I measured power at the driver, nothing in, nothing out, the DC is ok with no RF on it so something is sending the unit into a fault state. I contacted Icom and they said do all transmitter alignments and have done so, no change, any clues on this one? I did see an article that the AGC sense line needs a resistor changed from 0 Ohms to 330 Ohms if the unit had an early driver and a later one fitted but as far as i know this has always had the later driver, the serial number is missing off the chassis that makes it a bit more difficult to be 100% sure on what the build was on it. Any help would be greatly appreciated. Thanks Regards - Tony Eagling Vk7YBG

Driver board
12
Hello, I just joined this group. I do not have a 7000 but am going to work on one for a friend. It let the smoke out so by reading it's a very good possibility that it's the driver board. My friend has a new board! Yes a new one! How lucky is that! I haven't seen inside this radio yet but I should have it this evening. Without seeing it, my gut feeling is more heat sinking is in order if it's physically possible. I also read that Icom added a resistor to drop the current to that FET. Any hints and opinions are welcome. 73, Bob W4JFA (near Charlotte, NC)

Hf power out barely detectable
4
I purchased a 7K with no power out on hf. Vhf/uhf are good. Receiver is in excellent condition. I have set the driver and finals bias and are good. Gate voltage of the finals measures 2.4V. Power setting is 100% but measures negligible power into a dummy load. Is it possible the finals are bad?

Fair Price for IC-7000 Separation Cable?
7
I have the opportunity to purchase a second separation cable for my IC-7000. I am not 100% sure I really need it, but considering how rare they are now, if mine ever craters, or I want to move my radio around without pulling the cable out, or I find another IC-7000 to purchase (I'm looking) I'll be pissed I passed on purchasing this one. What's a fair price for one (used)? Grant VA6GT

SWR Meter on 2m / 70cm
2
I was at another fellow hams residence and since he had the equipment, I thought it would be a good idea to double check my antenna, coax etc. What is confusing is that he has both an old-school power meter (which was showing significant return power on my antenna run) and antenna analyzer (also showing higher SWR at needed frequencies), neither which coincide with what shows on the ic-7000 radio display SWR meter when I xmit. Then I read this in the manual.... The IC-7000 has a built-in circuit for measuring antenna SWR—no external equipment or special adjustments are necessary. The IC-7000 can measure SWR in 2 ways - spot measurement and plot measurement. The SWR can only be measured on [ANT1] connector, in the HF/50 MHz bands when an antenna is connected. However, when a 144/430 MHz antenna is connected to [ANT2], the SWR cannot be measured. Does this mean that when transmitting on 2m/70cm, even though the SWR meter "moves", it is not really accurate or reading anything meaningful? I've been assuming I had a good antenna run, but now I am doubtful (though it does seem to be working). I realize that the "graph" SWR meter does not work on 2m/70cm, but always assumed the spot meter was true... I've ordered a NanoVNA to do some additional testing. Any other reasons you can suggest that would cause the discrepancies? I did the standard multimeter tests for continuity etc while bending, twisting, and moving the coax etc...everything "seems" OK at the DC level. Grant VA6GT

IC-7000 accessory wanted
3
I'm still desperately searching for an MFJ-706 or MFJ-7000 for a special project. I believe the MFJ-706 was sold in greater numbers, but both types are physically identical and I can make the small electrical modification required to the 7000 version. Bob, G8IYK

TUNER Xmit Power on IC-7000
8
I cannot seem to find an exact answer in the manual or online. When tuning (in my case an AH-4), does the IC-7000 use a lower power? The AH-4 shows a tuning level of around 10-15W. If I have my IC-7000 on HF set to 100%, and hit the TUNER button, am I forcing 100W into the AH-4, or a reduced power? i.e. should I manually be dropping the power to 15%, changing frequency and tuning (or auto-tuning using PTT) and then manually increasing power back up again?

Ham radio Deluxe
5
Hello group. A drunk drove into my house and caused a bunch of structural damage, so we had to find a place to stay while the place is being repaired. I got my IC-7000 new right after they came out and had only used it mobile. Not wanting to take my large base station rigs for the temporary set up, I decided to take the IC-7000 with. I am having trouble getting the HRD software to find the radio. I programmed the radio with RT Systems software and that went fine, but connecting to HRD is another story. I have got HRD to work with many radios over the years in the shack but had not tried to connect and used the 7000 for this purpose before. So I wondered if I need a driver? I looked on Icom USA and find nothing. I tried to download a different driver on the Icom site, but was unable to download anything. I am stumped. I am not even sure what I should be asking. Thanks everyone and good DX. 73 -- Results not Excuses Bill AB9QU

IC-7000 for Go-Box?
16
I’ve been thinking to swap my KWD TM-710G out for a used IC-7000 in my QuickSilver Radio Hammo-Can Go-Box for use with Winlink and ARES work. I’d use it either 2m or 40m/80m HF. I’d have to add a SignaLink and LDG IT-100 Tuner carried in a separate box with a Win10 tablet, but that’s OK. Antennas would be 2m whip or 40m/80m loafed coil NVIS dipoles. Is there any reason why that might *not* be a good idea? The box has a 35Ahr battery and USB 5V ports to power a small fan to help cooling. Another option is a IC-7100 in a bigger box but that seems a lot of radio for a Go-Box. Bret/N4SRN
