SRC Mobile update

Although HF conditions in my opinion have not been too good lately, I have now had a little time to evaluate the SRC mobile whip.
It certainly appears to be a robust enough antenna physically and it looks well made. Using my LDG auto ATU I can now tune all bands from 80 to 10 metres. The antenna seems quite lively on receive, within the first few days of using it and under poor conditions I worked a DL station on 20 metres, he was calling CQ and came back to me straight away. I can monitor a local 80 metre AM net on my morning drive to work, although I would think that 80 metres is likely to be the worst band for this antenna.

Because the "Tune" function on my Icom 706 MK1 does not operate on 6metres I am unable to get the LDG atu to work on that band. I have found however that by tuning the whip up on 80 metres and then switching to 6 I get an acceptable SWR and indeed the antenna appears to work reasonably well on 6.

All in All I am pleased with the SRC. It is very convenient having all the HF bands available without swapping whips and the performance does not seem to be noticeably different from the mono band whips I had been using.

HF Mobile

A couple of weeks back I ordered a multiband HF SRC 8010 mobile whip from Snowdonia Radio Company. It took a while to arrive and a follow up email to the company wasn't replied to but luckily today the antenna arrived. The antenna with the aid of an auto ATU will, according to specifications tune from 80 metres up to 6.
I have tested it briefly on the car today, sure enough it did tune from 80 up to 10 metres and in fact it sounded very lively particularly on the higher bands. On 6 metres my auto ATU doesn't want to speak to my Icom 706 MK1 but I was able to get  what appears an acceptable match on that band (by tuning the whip on another band and switching to 6) and was rewarded by hearing a number of stations on 6m SSB as well as accessing a semi-local 6 metre repeater on FM.
The antenna looks to be well constructed. As I understand it the base contains a small balun which help in the matching of the whip. It will certainly be nice to have more choice of HF bands when I am mobile. Up to now I had whips for 40,20 and 10 and had to decide before setting off which band I would operate each day.

I will report back when I have had more time to assess this antenna but first impressions are good.

Matching my speed

Having finished work a little early today I was sat in the shack, I only had a few minutes as the YL wanted me to take a short walk with her. I decided to call CQ on CW  on 15 metres. Now at the moment I am still using a straight key and I would estimate my sending speed at around 12 to a maximum of 14 words per minute. I was only running 25 watts to my 80/40 metre dipole so I wasn't really expecting any instant replies but immediately UR8IB came back to me. Great.............but hold on, I think he was sending at about 20 words per minute. Well I am pleased to say that I got the basics of the QSO, name and report etc but it was a struggle. His CW was good but a bit too fast for me! Still I am making progress it seems.
On my trip home from work today I was also lucky enough to work on 20 metres SSB R50YG in honour of the Russian cosmonaut Yuri Gagarin.


The mystery of the TS830S goes on. Opening the PA compartment I could see nothing that had obviously blown. I removed and reseated the 6146 PA valves and checked and adjusted the bias adjustment as the manual states. I was then  able to get a reasonable RF output on 80 and 40 metres into a dummy load. Attempt sat trying to tune on 30 metres and 15 metres resulted in another blown fuse and a dead rig.I am lucky in that we have locally here an amateur who is experienced in working with electronics and particularly valved gear. He has suggested the trying a replacement pair of 6146's first (I have a few spares) if this doesn't make any difference he has offered to take a look at the rig.

Quality?

When I installed the HF gear in my car last year, it soon became clear that even though the antenna mount was installed on the bootlid (trunk) of my Volvo saloon car with an HF antenna installed it was long enough to hit overhanging tree branches etc. To avoid too much strain on the antenna and mount I purchased a spring on Ebay and installed that. The spring fits between the UNF mount on the boot and the antenna and absorbs a lot of the strain.
Last year I mentioned the disappointing quality of the Sirio antenna mount I had purchased although it still works it is rusting away quite quickly and will need to be replaced soon-not impressive after just around 6 months. That mount by the way is being used for the VHF whip, the 10 year old Diamond mount is being used for HF and still looks as good as new. I can't say the same for the Ebay spring though which had a shiny chrome finish but now looks like this:

Now I didn't pay a great deal for this little item, but it was the only one I could get. It still functions of course but looks awful again after 6 months. Yes it has been outside in all weathers but surely that it what it was designed for! I  don't want a rusty thing like this attached to my car! I have now painted it silver with some Hammerite paint so that it looks a little better. I wonder is it possible to get quality antenna items anymore or should be just accept that things are only going to last six months or so?
