472kHz preamp – a good idea?

The FT817 is a bit low in sensitivity on 472kHz so I was expecting a decent improvement with a preamp. To my surprise I am copying no more stations. In fact I am hearing just as many without as with! The result has surprised me. The rig sensitivity is definitely better with the preamp and stations are stronger but it is far from clear cut whether it is worth using it in reality. At the moment my 472kHz transverter does not have the preamp.

Maybe the FT817 sensitivity is good enough. In marginal cases (and these seem few) it probably helps, but most of the time it seems fine without.

Contentment with radios

After considering buying a new transceiver, I have decided to stick with the rigs I have. At present, my poor voice makes all speech QSOs an effort. I enjoy WSPR as this is really a true QRP mode and it tells me a lot about propagation, without shouting!

I’ll still “window shop” and might consider a new radio transceiver next year. I get by far the most fun from my $49 10m WSPR rig and my home-brew 472kHz transverter, proving that you do not need to break the bank to have fun. I am not against those who think differently – each to his/her own.

Our hobby – very diverse

There can be few hobbies that embrace so much as amateur radio. Some enjoy QRP, often making their own simple gear and each QSO is a thrill. Others spend a great deal of money on rigs, towers and antennas and enjoy just talking to others around the world. Some like the challenge of microwaves or optical.  The list is endless.

We are lucky that our hobby can be enjoyed by all ages and abilities and in so many different ways.  It is very easy to be critical of how others enjoy the hobby – I know as I am guilty of this!  We should be thankful we are a “broad church” and allow each of us to enjoy the hobby in the way that suits us best. I used to enjoy building and field work, but because of my stroke I have had to adapt. Thankfully, I enjoy the hobby as much as ever.

RadCom and the IC7300

My RadCom arrived by post today. Unlike in the recent edition of PW, the advertisers were publishing details of the new ICOM radio and were keen to take deposits. Perhaps they have got later data? I quite like the look of the new IC7300 radio, but feel the price will soon fall to £799 or less. I can wait. I may wait to see what the FT817 replacement looks like. A 5W (or maybe 10W) radio would suit my needs better.

The latest RadCom has a review of ICOMs latest flagship radio, the IC7851, selling for around £9000. Does anyone really spend this sort of money on amateur radio gear?  With PSU, tower, big beam and big rotator this implies over £10000 on amateur gear. I suppose some people must spend this sort of money. My FT817 has served me for over 14 years now. To me, this was an investment and I had to give it careful thought.  I wonder how many XYLs are happy for their husbands to spend over £10000 on a hobby?

Each to their own. If you really have that kind of disposable income how you spend it is your decision.

Yaesu FT991 issues?

The price is certainly falling for this rig, but quite a few people have expressed disappointment. I cannot comment on these reports. Some are disappointed saying it is, “cheaply made”.

This is a trend of our age: I have noticed that M&S underpants are now thinner and not as good. My wife recently bought a coat (not M&S) and this was thinner than the one it replaced.  No, making goods to fit a price seems to be the way things are today, rather than built to last. This says lots about our “consumer society”. Things are not made to last any more: they are designed to wear out or fail so we buy new items.

This is a state of affairs that ultimately cannot last.

5MHz band?

The next world radio conference (WRC-2015) is drawing close to opening. Worldwide, radio amateurs are hoping for a contiguous 5MHz allocation, rather than the channelised allocations common in many countries. A 60m band would be really useful as the sunspot numbers decline and the higher HF bands become far less useful for DX. Whether this contiguous allocation will happen remains to be seen. Most of the lobbying has been done, so I guess we now have to wait and hope.

ICOM IC7300 in RadCom?

My new copy of RadCom is due towards the end of next week. I wonder, if as in PW, there will be a “tight lipped” policy as appears to be the case for all advertising in PW a few weeks ago? You can almost hear ICOM saying, “do NOT sell the IC7300, as this is for NEXT year, if at all”.

Certainly the UK selling price of the Yaesu FT991 has, as predicted, dropped some way. This will go lower still in the months ahead. If the IC7300 has had to be delayed (software issue maybe, or are they afraid the lack of 2m/70cm will be a problem, or is there a major design issue, or are they worried about the selling price versus the Yaesu FT991?) this would be a great shame.

I was expecting to see this in the UK by Christmas and selling for less than the FT991. I now have my doubts. The next RadCom may give us some clues.
