Radio Replacement
I think he said that they told him it was the MHz crystal in the
original post. Dave M35 RST Engineering wrote: Then you've answered your own question. You are happy with what you've got and it is the least expensive option. The 170 series is the most bulletproof radio yet to hit the market, and I include the venerable old MK-12 (radios that glow in the dark). Jan Crystal (Ft. Myers FL, google on them for a phone number) keeps an incredible file of crystal specifications and I'd give it a 95% probability that they have that crystal spec on file. Last time I bought a 0.003% crystal from them it cost me about $20 plus postage, so for $50 you've got your crystal. Installing a crystal is about as difficult as changing your oil. Uncowling the ******* is the hardest part, both with radios and engines. Once opened up, finding the correct crystal to change is the hard part, but since your radio shop just changed the crystal, I'd bet on the one that is has the shiniest solder joints. I've got the service manual ... WAIT JUST A FRIGGIN MINNIT ... the 170 is a SYNTHESIZED radio; all the channels are derived from ONE MASTER CRYSTAL...either ALL the channels work or none work, with the exception of a dirty switch or a broken switch. Is it possible ... do ya think ... that your radio shop is BULL****TING YOU??? You've got two crystals on the com side of the radio. One is the kHz. crystal and one is the MHz. crystal. All the switches do is control a digital divider that splits the single crystal into discrete channels. Now, given that information, where do you think we should go?

All the switches do is control a digital divider that splits the single crystal into discrete channels. The avionics shop said that the MHz crystal was shot, and the kHz crystal was almost shot. Since I know that the radio has problems during transmit, I don't know what incentive the shop would have to be less than truthful. I did check with two other very reputable avionics repair departments, in addition to Gary Glassmeyer (who seems to have a decent reputation), and all of them said that the bench tech's diagnosis was either likely or could certainly be valid. What folks seem to disagree on is the ability to repair the radio. My local avionics shop is telling me that it is essentially unrepairable, which I've since determined isn't quite true. It is true that the parts to repair it are no longer sold by Honeywell, but they are available. Everyone is also telling me that parts are becoming more difficult to find. I think I've decided to have the radio fixed. I haven't completely decided on whether to have the local avionics shop install the used KX155 (I believe it has a GS receiver), because $2500 for the radio and install seems like a decent deal based on the used prices I've seen for the KX155/GS. The obvious disadvantage is that, should the KX155 fail, I can't swap in a KX170B...so maybe that answers the question. JKG |

Radio Replacement
Data point: A prospective buyer just told me he had decided not to buy my
airplane solely on the basis of its not having a 430 installed. A red herring to anyone not thinking of selling any time soon. Besides, even the 430 installation won't get anywhere near the money back as what was spent on it. Although an interesting anecdote, absolutely useless I think for considering what radio to put in the plane in question. Maybe, maybe not. I can tell you that when I was looking for an airplane just over a year ago, I would not even look at one that didn't have a Garmin 430 as a minimum. There are buyers that think that way and there are enough airplanes out there with G430 or better that a buyer will find one if it is important to him. I understand that buyers want one in the plane, however, buyers RARELY will pay for the actual cost of putting one in. That was my point. I was not arguing that it does not make the plane desirable - just that it is not worth the money just so that it can sell. For me it was as much about downtime as anything. I wasn't willing to buy an airplane without the panel I required and then have it be down at the avionics shop for weeks to months getting it the way I needed. There are lots of buyers out there with lots of different requirements; my point was there are some airplanes (those without a Garmin 430 as an example) that simply would not sell at all, to me, due to this deficiency. It wasn't that these airplanes were less desirable for me to purchase, they were not even considered for purchase. -- Ken Reed M20M, N9124X |

The point is that an older airplane without a 430 is more difficult to sell than one so equipped; hardly a useless consideration when considering a NAV/COM upgrade. Um, I don't see how it is a good thing to throw money away just so that the plane sells... If, at some time the owner wants to sell, he/she can always put it in the panel or reduce the price. Spending 12k on a 430 and then getting maybe 1k more on the sale over what was in the panel originally is not really worth it - you are doing yourself no favors. You're still not getting it. |

To me, it doesn't make sense to agonize over buying (or selling) a plane based on whether it has a 430 in it or not. In my case, even if I had the 430, there would be folks who wouldn't look at the plane because it doesn't have leather, or it doesn't have a newer audio panel, or it doesn't have an autopilot, or it doesn't have one thing or another that they're looking for. If I was looking at a plane, avionics would be one of the last things I'd look at, and when I did look at avionics, I'd negotiate the price down if I felt that avionics work was needed. At that point, it would be up to the seller to determine whether there was a market for his plane at his asking price. The reality is that, despite what some people may think, a 430 is not required equipment in an airplane these days, even if you fly IFR. There may be folks whose use of the plane will benefit from an IFR GPS, but my guess is that it is a true requirement for very few. JKG |

I think I've decided to have the radio fixed.
One other option, perhaps already mentioned, is the TKM MX-170B. This digital replacement radio slides right into the KX-170B tray, and works quite well. When one of our KX-170Bs went TU in our old Warrior, we replaced it with an MX-170B. It was bullet-proof, with better (and clearer) transmission and reception than our COM 2, which was another KX-170B. And, as I recall, it was much less expensive than fixing the KX-170B... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

The reality is that, despite what some people may think, a 430 is not
required equipment in an airplane these days, even if you fly IFR. The 430 today is what the Loran was when I started flying. If you didn't have an in-panel Loran receiver in your panel in the early '90s, you didn't have a desireable aircraft. Now, of course, they are all boat anchors (as the 430 will be in ten years) -- but back then, they were EVERYTHING. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

SO let me get this straight: You spend $12k just to make the plane desirable - the OP clearly stated he didn't need the equipment. Then the buyers will pay maybe 1k to 2k over the price of the plane without that 430 in it. And this is good advice? Thanks, I'll pass. I can navigate with 2 VORs just fine. |
