Data troubles

I had an idea to try and tidy things up in the shack and reduce the clutter. Why not use my under used Yaesu FT1000MP on data modes? I could then dispense with the little Kenwood TS450 I use for data, I could keep it as a backup rig or maybe sell it and buy some extra filters for the Yaesu.
So, I obtained a very reasonably priced data lead from http://www.radioarena.co.uk/. This arrived two days after placing my order-great stuff! I must say that although delivery was prompt there is no documentation with the interface whatsoever, nothing is labelled, even the two audio leads leave you to guess which is audio in and which is audio out!
Well this lead connects to the 5 pin DIN socket on the back of the Yaesu-labelled "packet"". I soon had the lead connected and was receiving PSK signals.Several hours later however I was still unable to get the rig to go into TX mode using Digipan or any other program. I could get data transmitted by manually keying the rig but no way of getting the PTT to operate via the interface. There could be a number of reasons for this- firstly the interface lead uses a USB rather than serial connector for which I had to install a Prolific driver. Secondly the Yaesu has to be set into "packet" mode for the PTT on the socket to activate, however despite doing all of this -no luck.
When DIGIPAN goes into TX the LED on the interface lights-so it is not a com port problem or a driver problem with the USB interface- the problem appears to be at the rig end. For now I have given up and re connected the little TS450 which works very well on data.This is not the first time I have tried and failed to press the Yaesu into use on Data.
The Yaesu FT1000MP is one of the few rigs I have owned from new. In fact it was the most expensive piece of equipment I ever purchased. For that reason alone I suppose I have tried to like this rig but in reality it is nowhere as good as perhaps I had thought it would be. for CW I prefer my old TS830s- it sounds so much nicer, for general receive I prefer my R5000 receiver, and the TS450 is easier for data. I guess the FT1000 does produce nice quality transmit audio though!

Radio Rallies

I attended my first radio rally of 2011 today. Held by the Swansea Amateur Radio Society at the Neath Sports centre.
This is not a particularly large rally but it seemed well attended and it was nice to meet up with some friends old and new. One of the highlights for me was meeting fellow blogger and local CW partner MW0IAN, Ian.
I came away from the rally with a few small items-a couple of BNC plugs, a dipole centre piece and some 300ohm feeder (I am thinking of making an HF doublet).
The next rally for me may be at the end of June (west of England Rally), these radio events are quite thin on the ground now, when I started in the hobby it seemed like there was a rally almost every other week!

Update

My confidence in CW operating is slowly improving. As well as a couple of QSOs with local amateur MW0IAN I have also managed a QSO on 80 metres CW with 2E0ROD in Peterborough. This evening I have some time in the shack and I was going to try a few CQ calls. Switching on the HF rig however I was met with S9 of noise over most of the HF spectrum. Lets hope it is only Temporary, it sounds like some localised electrical QRM.
As an extra incentive to improve my CW I have joined the FISTS club. Their website can be found here.

Because I have been concentrating on CW I have not been on the air on PSK31 for some time now, this was a mode which I was using quite heavily up until now. Whilst I am sure I will return to the data modes it is nice sometimes to be able to operate the radio without having a PC switched on. Maybe thats why I am not really interested in SDR at the moment. I have however been using a borrowed "Softrock" SDR receiver connected to the IF output of my TS830 to monitor the CW section of the bands and I find it very useful.

Ongoing project

The receiver pictured is a Realistic DX150A. Its a general coverage receiver from the late 1960's/Early 1970s. It is a simple, single conversion analogue set covering from Medium wave up to 30 Mhz. I bought it on Ebay as a "spares or repair/not working". Externally the receiver is complete and in good condition although it was quite dirty!
When it arrived here I connected it up to a 12 volt supply and was surprised to find it does work! It does however need quite a bit of attention, there is a broken tuning core inside and the BFO does not work so it only receives AM at the moment. The receiver has been modified in the past. You may be able to see the two BNC sockets on the rear. One of the BNCs is for an antenna, the other, well I'm not sure but I think the receiver may have been modified to take a digital frequency counter.

I haven't tried to connect the receiver to the mains supply yet. For one reason it has an unusual connector for the AC lead (I think this may be another modification) secondly there is a possibility that the transformer may be for a 110v USA type supply. I have a friend who has a variac and one I have sourced a mains connector we may be able to see what the correct operating voltage is using that.

I am hoping that trying at least to improve the receiver will result in some fun and some learning along the way.

First Step in CW

Fellow blogger and local Radio amateur MW0IAN drew my attention to a range of frequencies around 3570 on 80 metres where slow(ish) CW QSOs were to be found. I set up my TS830s this evening on that frequency and was monitoring when I heard a very strong station calling CQ. It was none other than MW0IAN himself! Well I had no excuse, he was sending at a speed I could read, nice clear CW and a strong signal. I had to reply. We had a short but enjoyable CW QSO, my first on that mode for over 20 years!
I felt it was a step in the right direction, I will be a little less nervous with my next contact on the key now that I have broken the ice so to speak
Pictured below is my CW station. Note the straight key- I need quite a bit more practice before I consider using the paddle.

Anyway thanks Ian for the contact, i don't suppose we broke any DX records- probably no more than 1km between us-but it certainly helped my CW progress.

An Interesting discovery

Following on from my last post it seems I have found the main source of QRM that was caused by one of my PCs at least. In the pic with my previous post you may have noticed  the "Black box" Icom PCR1000 receiver, sitting on top of my little HF linear amp. That receiver is connected to the main pc-the one I have moved onto another desk.Having moved that PC I found that the S9 of noise on 10 metres which was always there when the PC was on had disappeared. Today I decided to reconnect the Icom receiver. Since the Icom uses a serial port connector I use a USB to Serial lead out of the PC which connects to serial lead and then to the Icom.
Plugging the lead into my USB hub, Windows 7 automatically installed the USB to serial driver and then............S9 of noise on 10 meters. Moving the lead directly into a USB on the PC reduced this to S6 but unplugging altogether reduced the noise to nil.
I don't know why this lead should be radiating noise like this, but I will try and move the Icom receiver to be controlled by the other PC. Perhaps winding the lead around a ferrite ring would help? I think I have one here and will give it a try.If that doesn't work I think I will be moving the Icom on.

All change

I managed to find a space to reinstall the Trio/Kenwood TS830s on the Desk. Now all I need is a three way switch so I can switch my antenna between the three HF rigs. Whilst I was about it I moved the main PC further away from the radios. This has greatly reduced the QRM I was getting from that PC. The older PC which I use for PSK31 still generates some noise. In order to move that I will either need to get extension cables for the keyboard and mouse or maybe pick up a wireless mouse and keyboard set.

When I look at all the gear in the picture here it strikes me that the little Yaesu FT857D which you can see on top of my Yaesu FT1000MP could in fact do everything that all of the other gear could do, all in one tiny box. At present I just use the 857 on VHF. Perhaps I should clear the decks and use a minimalist shack based around the 857? :-)
