As far as power vs. battery life, it all depends on how you intend to use it. If you're mainly going to be accessing local repeaters, then a lot of power is not too important. If you're going to be doing a lot of simplex operation, especially with distances involved, you want to be able to run more power. I suggest that you make sure you get a second battery pack, so that you can use one while charging the other. If you want to spend around $100, you can get a 1 hour quick charge unit. Also, for mobile operation, you can get an car adapter to plug it into the lighter, thereby giving you full power (most battery packs that come with HT's don't put out the full 5 watts, usually only around 2.5. You have to buy an extra, larger battery pack for the full watts output). As far as features, you'll want CTCSS, so that you can access repeaters that require pl tones (important in crowded areas, or for closed repeaters). DTMF is important if you want to use autopatches. l consider those two the minimum requirements to get. Other nice touches are battery saver features, paging, pl tone scanning and stuff like that. > I am looking at models from Kenwood, Yeasu, and I-COM. I am > leaning toward the Kenwood TH-28A. I am also looking at the > Yeasu F-11R and 411 as well as a few models from I-COM. I have a Yaesu FT-530 (it's a 2 band, 2m and 70cm) and love it, especially the pl tone scanning feature. I'm not up on single band units. A previous reply to you mentioned intermod problems in large cities. I have heard that the Radio Shack 202 model is very good about not having intermod problems, since it is designed as ham band only. The drawback is you can't modify it to work as a scanner, it's a little bigger than most new HT's, not as many features, and many people are prejudiced against Radio Shack products. However, I have found several people on here and on Genie who are quite pleased with theirs.

We have found that power is not greatly significant unless you are in a poor location. MOst of the time we use 2.5 watts, but have the capability for 5W. DTMF - a resounding yes for the occasional auto patch, especially for emergencies and 911 service. We don't use CTCSS/paging, but it would be a nice feature if my wife ever decided to get her license. Battery life is not critical as long as you have a second battery. We have a couple of 7 amp hour gell cells that we can plug in for longer term operation like going camping. I had a 28A and found it susceptible to intermod, even in my distant location from the big city. It had some great features: I especially liked the clock radio feature that would turn it on at the time I preset, so my commute group would wake me up and get me going <HI>! We have ended up with three Alinco DJ-180T/H. They are not fancy, but do the job very well (3 hams in our family). I bought two of them with the 12 volt battery, and mine has the 7.2V battery. They have DTMF, scan, and memories, as well as out of ham band receive, but no real "frills". I am currently using mine on my packet station until I convert over to a mobil unit. Another recommendation is the Yaesu FT-530 dual band. It is a great radio. My son's friend just bought one after involving us in their search, and it really works well. My son is saving up for one (in fact he wants to sell some of my equipment to get some money - cheeky 13 yr olds!).

Hmm this takes me back a couple of years, the first TS850 I saw was on a stand at a rally. There was a large crowd around it, fighting to spin its knobs and poke its buttons. It seemed rather futile, really, as none of the stands had any electrical power, and the set was consequently unpowered. They must have really liked the feel of those knobs because some people were offering to buy it there and then, untried. One individual in my hearing offered the stall holder a premium over the list price just to get that one, said to be the first in the area. To fully understand the meaning of this, readers in the US must note that in the UK, list price is strictly selling price, although you might get them to throw in an accessory worth a few percent of the deal. UK list price is about double the US prices seen in QST. I was somewhat stunned by this, and have watched for the effect recurring, which it did at another rally when the TS50 showed up. I have witnessed people buying radios by appearance ! I just can't decide whether it is a joke or not, although P T Barnum would have found it funny....

Anyone know how??? Jay, I looked high and low for a smiley face in your article and didn't see any, so here goes: It interfaces exactly the same as it did on the TS-430. Connect the antenna jack of the rig to the radio input on the tuner, using an appropriate cable such as RG-8/U. > Please help! the AT-250 works (tried it out on a 430.) Congratulations, you already had the answer and didn't know it. The AT-250 came out before the TS-440 transceiver, which is why it is not mentioned in the AT-250 manual. I sure hope you didn't think the AT-250 would be like the fully automatic internal antenna tuner of the TS-440S/AT. You still must perform all tuning adjustments manually, using the "tune" button on the radio to key with only 3 watts output. Higher power tuning into high VSWR (VSWR>7:1) can DEFINITELY cause component failures in the TS440.

Was: FT-990 vs TS-850 It seems that the SSB quality depends on 3 factors: 1. Passband characteristics of the AF chain (including the microphone), 2. IMD of the PA, 3. Type of processing, audio or RF? I am wondering why the QST reviews do not mention the type of processing, which has a large effect on signal quality. Signals with audio processing have higher content of AF harmonics, and are subsequently less efficient (3db?) and more difficult to tune. All cheaper rigs such as IC 725-737, FT 747-757, TS 430-450 use AF processing. IC 751-, FT990-, TS 830- use RF processing. I am not sure about the rest.
