Kenwood’s TH-F6 is very compact handheld three band transciver for radio amateurs. It can be MARS modified, allowing extended transmit ranges. The radio is NOT type accepted for commercial use. The radio comes with a reasonable sized battery pack, a wall charger, and no case. I’d recommend getting a larger Battery Pack, there are some really large packs available. The radio has a power saver feature, which basicly turns the radio off for some many milliseconds every second. This is a nice feature, but if it is in power save mode, you will miss the first word of a new call. This feature is well worth the few missed words as opposed to losing the radio to a dead battery.
There are a few foibles with this radio:
- Sometimes it will refuse to turn on. I believe this only happens if you let the battery get really really dead. Other than when I let the radio die, I do not see the problem. This appears to not be specific to my radio only. I see comments on the Yahoo TH-F6 group indicating some others having this problem as well.
- If you replace the antenna with an aftermarket antenna make sure it has a wide base covering the area around the connector at the top of the radio. If you don’t, you run a pretty good chance of breaking off the connector on the radio body. Again, see the Yahoo group for more information on this.
- Without a good low band antenna it is a brick! If you don’t give it a good external antenna while using it for SWLing, (yes you can do this), the radio is a brick and hears nothing, or almost nothing. If you give it a good external antenna, it suddenly sounds pretty good. This seems to not affect the performance on the AM broadcast band.
- The stock battery pack does not come with exteranal charge pins, thus, you will have to dismount the battery to charge it in an external charger, or plug the radio into the Kenwood supplied wall bug charger. I thought this would be a royal pain, but it really is not. If you get a few additional battery packs, you just swap them out if you also get an external pack charger.
- While the radio is on charge, you can not transmit. That is why you want to get additional battery packs, and an external pack charger.
- I have seen one TH-F6 in which keypad was becoming disfigured from use. The keypad is a rubber overlay, which appears to be painted on a white backing. As wear happens, the white begins to show through. This happened on a radio which was kept in the much too tight after market case.
- The after market case from Kenwood is so tight it almost does not fit! Not kidding, I thought I was going to split the canvas case open getting the radio in it the first time. The case does not stretch, nor does it even fit the radio well, so don’t even bother to buy the canvas case. I have not seen a leather case for it, so expect to use the radio without the case. I suspect this is why the keypad was wearing so badly in the one radio I saw which had the keypad issue mentioned above.
- The menuing is a bit complex, but very learnable, unlike other radios I have seen. You should get one of those nifty instruction cards for the radio.
Now lets look at the pluses:
- This is a small radio, by small I mean really small, it will fit in your shirt pocket with room to spare. I really like the size, it is 2.3 x 3.5 x1.3, and weighs in at 9 ounces.
- It is very light weight, but does not feel cheap at all. In fact it feels really solid.
- The battery packs remove very easily, and are mounted securely as well.
- The dials on top are split, so it is fairly simple to operate the radio from the dials.
- Adding external Mic and Speaker is simple, there are several after market headsets designed for this radio. They all plug into a connector on the side.
- The MARS extended transmit mod is really simple, and almost anyone can perform it.
- The radio is easy to use, and programmable via a computer.
- Once programmed, the radio is really easy to use, and it allows Alphanumeric labels on the dial.
- It does SSB!! Yes, you can listen to your favorite low band net with this radio. You will need an external antenna for 100 KHz. to 1300 MHz., (cell blocked), but you need one for your big expensive transceiver, so this is not surprising. It also does both the AM and FM broadcast bands, without an external antenna. Given I have this radio for SAR/MARS/EMCOM use, I find those features very good to have. The radio has a built in ferrite bar antenna for use in teh AM broadcast band. It is supposed to work for 80-10 Meters, but it really does not work well.
- Twin radios in one. The radio has two band, and you can listen on either, or both at the same time.
- VOX for use with those after market headsets you will want.
- Keyboard lock, this is very useful on a radio this small.
- Three power levels, 5 Watts, .5 Watts, and .05 Watts. Great for when you are under the repeater; select .05 watts and your battery will never run down. Front panel selectable, using a single button.
- MIL Standard: MIL-STD-810 C/D/E
- The radio has an amazing receive range: 100 KHz., to 1300 MHz. Cell frequency’s are blocked of course.
- I removed the belt clip from my radio for some reason that escapes me now.
Conclusion
This is a fine addition to any ham shack, and seems to be very durable. I have had mine for four or five years now, and still love it. I have used it to listen to Fire, Police, Weather, Ham, and just about anything else I could think of. Using the dual radio feature, you can listen to an emergency service, while also listening to your local repeater. This makes it a very small package, for doing a number of very important functions during EMCOM activities. Would I buy the radio again, no question. In fact I am considering buying a second one as backup.










Regarding your statement about; ” Single button simplex checker. Just press the little button above the PTT switch, and you are listening on the repeater input frequency.” I’m sitting here with my F6A in my hand and I don’t see any little button. I do see that the 8 button has “REV” on it and that does show the input.
Other than that you’ve got a good review of this compact radio.
Hi,
Thanks for catching that…
I also have the Diamond tri-band antenna on this radio and it works well.
You can transmit while charging, you just cannot do it at high power.
This radio is due for a replacement / update from Kenwood.
A few years ago I spoke to one of their staff about this at a big hamfest. I recommended that they combine the best features of the F6A and the D7AG. IOW, a slightly larger radio with the RF performance and memory of the F6A and the data capabilities of the D7AG or D72. The guy laughed and said that was a great idea and that he would be the first to purchase one. He also said that it would never happen. He said that those two radios combined are the best selling handheld that they have. I was puzzled and asked “you mean handhelds plural”? He said no. They understand that HAMS who purchase the one model, then often end up purchasing the other one too. From a sales standpoint they are making more money that way, than if they had a single model that had the best features of both.
So Sales and Marketing practices dictate that we may still have to have a belt full of HTs.
Wonderful little radio. I’ve had it for about three years and have no regrets on this one. Added the Diamond aftermarket antenna and I highly recommend it. Able to hit the repeater 90 miles away on 5 watts!
Thanks Chris…
That’s a very cool little radio! I’ve got a Yaesu VX-3R, and recently bought my 13 year-old son a $50 dual-band HT that he likes.
Glad I found your site, nice work.
Could you review some of the QRP radios?
Also the ZM-2 and the ZM_4 tuners?
And some the new Ten-Tec stuff?
Hi,
I will as I can afford these items… I need a good QRP radio, so that is coming as soon as I get it. Will also need a tuner for it… :)
Thank you sir!
Great website. I enjoy ready it. 73′s John
