IC202 - remember these?

Back in the late 1970s (I think) these became very common on 2m SSB. They were the successor to the Liner-2 and far cleaner. I had one for several years and it served me well. Even today, they are still in use driving microwave transverters.

I hope the links on the link still work as they were created some time ago.

IC202 and similar

After the Liner-2 made 2m SSB popular in the early 1970s, the IC202 was introduced by ICOM. This had less power, but was cleaner. It had a wide coverage VXO, but it behaved like a VFO. 

To this day, the IC202 and its successors are used to drive transverters. In the past I had the IC202 (2m) and the IC402 (70cm).  There were later S versions with a number of improvements. These were nice simple rigs with no frills. They had no memories or sythesisers.

I used my 2m IC202 with a homemade transverter on 10m. With 1W pep SSB and a low wire dipole the world was worked.

IC202 2m SSB/CW

Nostalgia time again....

Way back, I owned an ICOM IC202. This was a 2m SSB/CW VXO controlled rig. The VXO covered 200kHz and behaved like a VFO.  It had a very "military" look. 

Later, it was replaced by the IC202S. Many still use these today to drive microwave transverters. I used mine on 10m with a homebrewed transverter. It worked some impressive DX with 1W pep on 10m SSB with just a low wire dipole antenna.

2m SSB

These days 2m SSB is nothing new, but back in the 1970s there was no VHF SSB commercial gear until the Liner-2. After the Liner-2 came the IC202 followed by the IC202S. These were military styled handhelds. The FT290 came later followed by the FT817.

A blast from the past on 2m SSB/CW

Back in the 1970s, in the early days of 2m SSB, the most popular rig was the Belcom Liner-2.

Hot on its heals a few years later came the IC202 from ICOM. I had one of these and even used it on 10m with a Microwave Modules transverter. With internal batteries it could be used portable and even handheld. Some great DX was worked with it on 2m SSB and on 10m SSB using that transverter.

ICOM IC202 and IC202S

Probably few will recall these QRP portables. They were made by ICOM and followed in the footsteps of the Liner-2.

They had a very good VXO covering a decent part of the SSB band on 2m. Similar rigs were made for 70cm, and, I think, 6m, although I am unsure about this. I expect someone will tell me! (see below)

As you can tell, these had a very "military" look. Mine was mainly used at home, although some impressive 2m SSB DX was worked portable with just the whip antenna.

The quiet VXO made these rigs popular for IFs in EME rigs. I owned an IC202 and used it with a transverter on 10m too. Much DX was worked on QRP SSB.

UPDATE 1535z: Well, Bas (see comment) has pointed out the 6m version was the IC-502.

2m SSB history

IC202
For me, 2m SSB began with the purchase of a 10W pep Belcom Liner 2, which opened up 2m SSB to the masses. Before then, people used homebrew transverters and HF rigs to get on VHF SSB.

After that I owned the IC202 from ICOM which had a very good VXO but less power (3W pep).  Later, the first digital synthesised rigs appeared and 2m SSB really took off.

In the last 20 years or so, certainly here in the UK, VHF/UHF SSB took a nosedive and what little VHF/UHF activity there is is mainly using FM. Here in the UK there is good SSB activity in contests and in good lifts, but little casual use of the SSB/CW modes, which is a pity. Ranges on SSB can be much greater than FM for similar power levels.

When I first used my Liner 2 I was amazed how far I could reach in flat conditions, even with 10W and a small indoor antenna.

Belcom LS-707 70cm multi-mode rig

A radio amateur in Nottingham,Vic G0RVA, recently bought one of these Belcom rigs. It appears to be an all-mode 70cm rig, although I am not familiar with this unit.

I know Belcom did a 2m version (the famous Liner-2, which I did once own) and a similar version for 70cm. The Liner-2 was a modification of their 10m version, which I don't think was ever sold in the UK.  Inside Vic's rig was what looked like a canned preamp with the marking "AngleLinear" but again I am not familiar with this unit. Angle Linear appear to be based in the USA http://anglelinear.com/ .

In its day, the 2m Liner-2 transformed 2m. It was a synthesised SSB rig and was frequently pushed too hard so that splatter was a problem. I was amazed how far I could work on 2m SSB with 10W pep. From Cambridge I could work stations that would have been impossible on FM or AM. I found I could work 200-300km with a simple antenna under ANY conditions.

Many were critical of these early Belcom transceivers, but I enjoyed my Liner-2 as did many others. Later I bought an ICOM IC202 which was a better radio, but with less ERP. The IC202 had a mock military style, that really was not too clever.

The "coming of age" of 2m SSB marked the change from "tuning high to low" to single frequency working. Sadly, there is far less activity on 2m SSB outside of contests so people think VHF is only really any good for local QSOs. With 10W SSB, or even less, it is possible to work a long way on VHF irrespective of conditions. From my current QTH, I think 200km is reachable with 5W pep and a 3 el beam on 2m. It is not that different on 70cm where I use 5W pep and a 5 el beam. Both my beams are hand rotated.
