Separation cable comes with it.ДЄlso likes is the computer program to load frequencies, power, CTCSS etc. This is important with today's smaller cars. Mine are mounted under the passenger seat and the display where it can be read easily. If tested with more than a 1:1 SWR, the radio will lower its power to avoid frying a final.

I was a professional radio technician and had access to test gear. How does the radio detect this and load into a memory? The radio with the least keystrokes wins. Example: what if there is a repeater on the same frequency in another area, but on a different CTCSS.

When I buy a new radio, I download manuals and play 'what if'. One was bought new in '03, the other used from a friend getting out of Ham Radio 2 years ago. In sum, I very much like the 208H and would like to buy another for permanent mounting in my ute but they very rarely appear on the 2nd-hand market. Icom make some very good quality UHF CB rigs for that market segment. Would be nice if Icom would hardcode a 476-477MHz lockout into the main CPU of future 70cm capable rigs. This has contributed to a number of Australian 4WD enthusiasts taking up the 208H as a VERY high power UHF CB transceiver (Aus UHF CB power limit is 5 watts, yet the rig will put about 45 watts into a dummy load when programmed to transmit in the 476-477MHz Aus UHF CB band).

Lastly, it is far too easy to mod the rig for out-of-band transmit operation, which requires only the removal of a couple of diodes from a matrix. It's surely necessary considering how hot the chassis becomes when using high power, but it'd be nice if it was activated by heatsink temperature alone and were variable speed to reduce noise when in operation. The second complaint is the noisy cooling fan which activates upon transmitting regardless of the temperature of the heatsink.

It is far easier to use a PC, data cable and programming software to perform this function. Programming memories, whether from the front panel or mic buttons, is cumbersome.

It's the first rig I've owned where I've had to consult the manual to set the op freq and use the scanning feature. The worst of them is the general difficulty in basic operation.

I have just two complaints about the 208H. I'll suggest this is the price paid for the extremely broad receiver bandwidth, which may be a nice feature on a spec sheet though I suspect is rarely used by most owners. The rig makes rated max power on both bands, but it'd be nice if it had a 4th, extra-low power selection, perhaps 500mW, to conserve battery power in extended mobile/portable operation.ДЄs has been noted by others, the receiver is prone to intermod, but in most cases the attenuator function engaged by advancing the squelch control into the last 1/4 of its rotation is sufficient to suppress the intermittent intrusions of extraneous noise. The internal speaker is quite good considering its small size. The transmit audio is always complimented in simplex service- the local 2m & 70cm repeater has comparatively poor audio fidelity. At worst, they contribute a 'cheap' feel to the rig which is wholly undeserved considering the brick-solid construction of the rest of the rig. I agree with several other posters that the volume & squelch pot shafts have a excessive amount of lateral play, but this doesn't appear to affect their smooth and noiseless operation. This one has survived a few knocks and getting rained on briefly without complaint. I picked up a 2nd-hand 208H a bit more than a year ago with the intent of using it as the main shack 2m/70cm rig, but it has been pressed into service as an impromptu mobile on a few occasions. Great performer, durable, hard to program Separation cable screws on to the front attachment (Can't easily be removed for security) I get a lot of engine noise when used mobile Very complicated menu and programming setup The front attachment is not so heavy duty (wobbly knobs) + The main radio is very heavy duty and solid (UK version)Д®arlier 4-star review posted by GM1EXK on TX Audio is Low (apparently the FM Deviation is only set to 3.5khz from factory)Д¬an't set it to auto repeater shift in the repeater block. The Fan comes on regardless of TX power and temp and is LOUD! Average or slightly better than average selectivity
