I was up in the loft this morning looking for a couple of bits (with an eye on another project) when I came across the microphone for my Icom IC-740 - my first HF rig from when I was licenced in 1983. Being a bit of a hoarder - well who would want to buy such a vintage rig (!) - I have never disposed of the rig. For years I kept it at my parents home in Cornwall, so that I could operate from there when I visited. Now they are no longer there, the rig has been living in our loft for probably the last 6 or 7 years lying unused.
Time to try it on an antenna! I plugged the HF vertical into the rig and the receiver was working well. Tuning around was quite pleasant. The VFO was a little more 'plasticy' that some of the other rigs I use now, but the receiver was ok. When I bought the rig, I used the 500hz CW filter pretty much all the time. Nowadays I am happy to tune around on a wider filter, but it sounded nice enough. Sadly the S9 noise on 14MHz experienced on the other rigs was still there on the 740 (I didn't expect it to be otherwise!).
When I was living in Canada in the mid 90s, the local radio store in Toronto, Atlantic Ham Radio were closing out some of the modules for the IC740, so I had installed the keyer module and the FM board, which I didn't buy in 1983 - I had only just started work and I'm pretty sure that the rig was several months wages as it was!
Anyway, I plugged in the paddle, turned the power down and had a play. It sounded ok! The keyer chip was obviously a little different to the keyers I normally used as I was dropping the odd dot here and there, but quite manageable. I had a listen on another rig in the shack and the signal sounded fine, so I decided to see if I could make some QSOs.
Forty metres seemed like the best bet, so I tuned the CW end looking for a nice strong CQ to answer. PA/ON6QO was CQing from IOTA EU-146, so we successfully exchanged reports. I then found Rob M0TIX calling CQ and we had a longer ragchew on the key and I explained I was using my very first HF rig from nearly 30 years ago. Finally, I decided to try 10MHz - when I first had the rig, the 10MHz band had only just been allocated to amateurs and I had to do a modification in the rig to enable the 10, 18 and 24MHz bands! Tuning up 10MHz I heard W1MK calling CQ (not bad for the middle of the day), so I replied to him and we had a short but pleasant QSO.
Perhaps sometime I will try it on SSB. I remember that the audio reports on SSB always were a bit poor - perhaps one of the reasons that in my early years on the air, I concentrated on CW operation! As I recall the Icom microphones of the day had a preamp in them.
A happy distraction with the old rig and I am delighted that it is still working. I will have to think of a use for it! Now, back to the original reason for the visit to the loft....
