Re: Krystaly crystals needs crystal parameters for MVP

 

OK, I placed the order this morning. About 1/2 the price of QuartSLab & will take about a month to ship; will let yall know how they work. I told Josef @ Krystaly if their crystals work well he may get a bunch of orders for more.

+/- 10 percent in tuning.?
See what they would charge you for a retune. ?It may be a lot cheaper than a new one.?

Our club was gifted a Sinclair I-2113T ferrite isolator tuned to 152.210 MHz.
Can this be retuned for use on 2 meters or is it a paperweight?

I've never had a problem retuning a 152 MHz isolator down to 2 meters.

I¡¯ve never seen an isolator you could ¡°tune¡± to a specific frequency. ?On the other hand I¡¯ve never seen one that lost all matter of directivity if the frequency running through it changed by a couple picohertz. Now granted 10mhz at 2m is not insignifigant and my guess is there may be some performance degradation both in loss and isolation. The question is really, ¡° is that increased loss and decreased isolation acceptable for your application. My suggestion would be simply to sweep it from say 140-160 and see what you get for isolation and loss. A directional coupler and decent service monitor or spectrum analyzer ought do that just fine as you don¡¯t need phase info for this.?

That is the replacement fuse I ordered and used in a Motorola R2600C. It looked identical to the blown one I replaced.

tnx Bob for the comments
Do you know where these "smaller"fuses might be available?
tnx

While the Picofuse is what everybody recommends, take a look at the outside diameter of the fuse, then measure the inside diameter of the hole in the back of the BNC connector to verify that it will actually fit. I think you'll find that the hole in the BNC is under 0.1 inches while the fuses are over 0.1 inches.

There are other fuses that are a bit smaller that might fit better.

Jerry,
That fuse should work just fine. Your choice of the very fast acting style is the correct series for the antenna input fuse.

I think that is a very fair price for 5 of them.

Looking for TK-x80 control boards

 

Through all my Kenwood TK radio acquisitions I ended up with 2 or 3 radios with functional main boards but the control board/CPU is dead, so I'd like to find some control boards to revive those radios. They can be from any TK-x80 series mobile (TK-780, 880, 980 or 981), as I believe they should all be interchangeable. So if you have one of these radios with a dead RFPA, deaf RX, PLL that won't lock etc. but the display works & will still talk to the KPG-49D software please contact me directly at no6b@... . Thanks.

Working, used TKR-750-1 programmed for 147.06/plus offset/no pl. Puts out 20 on the power up setting or 48 watts on high power.
No power cord, no manual, just a bare working repeater. Box is from an 850. Asking $300 if you can meet me some where within 100 miles of Midlothian, Texas. Or, $300 plus actual shipping. You choose your method of shipping except USPS. Nope. They loose things.
Or make an offer I cannot refuse. lol...
