Re: ic9700?

Bob Lockley VK6KW
 

Hello Alan,

I am looking for an IC-7100 with the 4m or 70MHz option as I have 2 of NEC-500 towers (5.7 and 10GHz respectively) that both require a 70MHz IF … so if yours fits that bill and you are tempted to upgrade, please let me know.

 

On that score I would like to hear from anyone with a working IC-7100 going spare. Or a 70MHz module for the FT-736R???

 

73 & happy DX,

Bob. VK6KW.

Hi 

 

You’ve got me worried now. I was hoping to get into 23cm as a newcomer by using my existing IC-7100 and a bought transverter from SG Labs to get me on the air. I have been studying the effects of ALC overrun to ensure I keep any spurious emissions to a minimum and I have also done the path loss calcs because I want to learn and do this hobby properly.

To Alan, M0JIO.

 

Hi Alan,

 

At the moment I drive an SG-Lab 23cm transverter with 3w from an IC-706MK2g (the least I can get the power down to using the internal twiddle pot, I don’t use the menu power setting) and I don’t suffer any overshoot that I can measure. Even with G3XDY QRO not too far away I don’t suffer any ‘crunches’ on receive.    I also use it on 432MHz  with a 13cm SG-Lab transverter.

 

I am soon going to dedicate a ‘Mutek’ed’ IC-271e as the prime mover for 23cm so we’ll see how it goes with that.

 

Good luck on 23cm

 

Best regards

 

Colin de G8LBS.

Re: ic9700?

SAM JEWELL
 

I would echo what Paul says. Directive antennas and higher propagation losses mean that 23cm is not as 'sensitive' to radio strong signal performance as, say 2m.
Where there might be a problem (on receive) is if you have a very nearby 23cm beacon (or radar). The GB3MHZ 23cm beacon, near Ipswich, provides a very strong 'test' of 23cm receive performance, for those in the area. 
Directive antennas are a real bonus.
Please give 23cm a go. Don't be put off by the discussion about equipment shortcomings. 23cm is a fascinating band with great DX potential.

Hi Algernon,

Welcome to the microwaves.  I would not be too worried.  I have used an SG labs transverter in combination with an FT-817 on 23cm and found the results to be surprisingly good.

If you are using an IC-7100 then as you have already discovered, the main issue you will have is with reducing the max 50 watts at 144MHz to a level suitable for the transverter.  Andy G4JNT gave excellent advice in an earlier thread on how to use an oscilloscope and simple RF probe to check for an initial power surge as the rig's ALC kicks in to reduce the power to your desired level.  The FT-817 is popular as a transverter driver because it is a QRP rig and therefore there is less chance of putting out a bad signal or - just as importantly - frying your transverter due to equipment malfunction or just twiddling or forgetting to twiddle a knob.

If you are going to run the SG Labs transverter barefoot (ie 2 watts) then obviously the scope for being a nuisance on the bands is much reduced. I doubt anybody will be concerned about your signals at all unless you are very close to another station.

If you are running into a high power amplifier then you need to take greater care.  But please don't let these discussions put you off.  Most of the complaints about modern VHF rigs are related to high power use on 2m and sometimes 70cm.  By the time you get to 23cm, you are in much safer territory from a poor Tx point of view.  Obviously it depends on your location, but most of the time you'll find you can't hear anybody at all on the bands at all unless you are pointing your antenna directly at them or they are pointing directly at you.

And most microwavers are incredibly helpful people who want to encourage activity on the bands, so if you run into trouble on the uW bands, you are much more likely to receive offers for help rather than a grumble.  If they only had an IC-7100 and an SG labs transverter available, I think that most experienced microwavers would put their combo on the air and check with neighbours etc. to see how it sounds.  

So my advice is to get on the air and use it as an opportunity to learn.  Hope to hear you on 23cm soon.

Re: ic9700?

Paul G4KZY
 

Hi Alwyn,

I'd like to keep this positive, so please don't take offence at what I say or think I'm trying to criticise.  I would like to hear people's views for a reasonable alternative to the 9700 in various applications.  Ben asked if the 9700 would make a good replacement for his FT-817 as a microwave transverter driver and lots of people said "No!" for various reasons, but few suggested a good alternative.  Whilst far from perfect, I think a 9700 would be an improvement over an 817 in nearly every aspect.  Maybe I’m wrong, in which case perhaps others can suggest a better option?

Your views (Alwyn) are rightly considered authoritative, which means people will listen much more to what you are saying than what the likes of me are saying.

It is interesting that you think the Rx performance of the 9700 is its greatest weakness, and if I remember rightly, you measured (or perhaps reviewed) the Tx performance of the 9700 a couple of years ago and mentioned that on 2m it (just about) meets the RSGB VHF contest transmit composite noise specs for small stations.  Most complaints on this thread are about the Tx performance – principally on 2m I think?


There are some whose definition of "serious contesting" involves 4 or more antennas and one or more kW amps.  Clearly a 9700 is not appropriate for driving that lot.  However, I think that many folks use a 9700 it for what they consider serious contesting, perhaps in the AR sections or low power sections of RSGB contests.  The 9700 is, IMHO, a good option for this, and they are used by a number of well-regarded contesters.  After all, for a 100W power output, the "serious" alternative might involve an HF rig, a transverter (hopefully not from Ukraine) and a linear amplifier (hopefully not an MML100).  The scope for "inexpert" operators getting a bad signal out of that combination is far greater than the scope for overdriving a 9700.  So, it would be good to hear about others suggestions for a simple mobile / portable setup for an AR contest entry which would be an improvement on the 9700.

Similarly, I'd be interested if you could elaborate on what you meant when you said "its greatest weakness is the poor A/D accuracy on receive which makes it not much use when a band is busy."  Apart from a high quality HF rig and transverter, is there a better alternative?  The main problems I had in last week's UKAC were related to the S9+10dB intermods from the next-door station and AFAIK the best receiver in the world can't do much about that.  Again, is it that you need to put 3 or 4 boxes together to get an improvement, and if you do that how much improvement can you expect?  In other words, how busy do the bands have to be and how useless does the 9700 become under those conditions?  In fairness, I think your talk last year was very illuminating on this particular topic.

Going back to Ben's question, what would anybody suggest to replace his FT-817 as a driver for microwave transverters with IFs of 144MHz and 432MHz, as is an improvement over a 9700?

 

In closing I want to observe that your talk at the Convention last year has been widely praised, and I for one found it both fascinating and educational.  It made me think of a number of different aspects of my station which I hadn’t thought of before and it serves me as a useful reference for performance benchmarks,  Thank you for your work, and let’s hope that the likes of ICOM and Yaesu are listening.

 

Best wishes,

Re: ic9700?

Dear All,

Just to say that since my RSGB Convention talk, where I showed the radiated noise (amplitude noise rather than phase noise is the big problem with the 9700) performance of a few different systems, I’ve had quite a few people asking me for advice on the bands and many are keen to improve their signals.

Of course, there will always be some antisocial operators, but I do think they are in the minority.

I use a remote controlled 9700, which I find useful, but would never use it with a PA or for serious contesting.

For me its greatest weakness is the poor A/D accuracy on receive which makes it not much use when a band is busy.

For microwave IF use, I would think the drift would be an issue, unless it is modified to lock the VHF XO.

Regards,

Alwyn G8DOH
