[Repeater-Builder] Re: Repurpose a Mitrek UHF PA
Eric, Could you please give us a little more information please. What radio are you presently using for your UHF repeater? Does it have a preamp and if so what type? How much power out of the repeater transmitter do you presently have? Also what are you currently using for a duplexer and antenna feedline? The answer to these questions will help us determine if a move to a 100 watt PA is technically a sound move, or if other parts of the system will need to be upgraded as well to support the higher transmitter power level. While a lot of repeaters and links are made from Mitrek's including some of ours, I do not consider a Mitrek mobile PA to be continuous duty in any fashion, although at reduced power levels with added forced air cooling they perform very well.

[Repeater-Builder] Help ID Fan Control Board Kit
Some time ago I purchased a fan control board kit on eBay. Now that I want to put it together, I find that I don't have a schematic or parts list to help me sort out what goes where on the board. The PCB is about 1 1/8 x 2 3/4, and the circuit uses an LM393 dual comparator. I've found a lot of interesting things looking for it on the net, but at this point I'm really hoping that someone will recognize it and bail me out. Jeff W6JK
Re: [Repeater-Builder] Repurpose a Mitrek UHF PA
I know of a group that did exactly what you are talking about with Mitrek boards about 10-15 years ago. It was a HELLUVA lot off work to get it right, and a pain to work on when it failed. Get a power amp meant to do the job, or stick with 40-50 watts (no one will notice the difference anyway)! -- Original Message -- Received: Sun, 31 May 2009 10:38:56 PM PDT From: Eric Grabowski ejgrabow...@yahoo.com To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Repurpose a Mitrek UHF PA A local ham radio club wants to add a 100 watt continuous duty power amplifier to their UHF repeater.

[Repeater-Builder]
My first UHF repeater used exactly this setup. I cut off the PA assy from the rest of the radio and milled the fins off of the casting. This was then attached to a large heatsink and rack mounted. I used it for at least 5 years and then sold it to amother Ham who donated it to the Wheaton Community RA club where it was used for several more years before it was run without an antenna one day. I used a 45 watt PA but there is no reason a 100 watt could not be used the same way. Just cover the circuitry very tight or remove it before milling.

[Repeater-Builder] Re: MSR-2000 vhf on 2m
Hi Norm, The internal duplexers are commercial wide split and won't do the classic Amateur 600KHz repeater offset... so they go away (you sell or trade them off to a commercial radio system operator like me as an example). The repeater will tune right up into the ham bands but you should reduce the transmit power output to no more than 60 watts (to help protect the rf power amplifier). Here are a number of Amateur Radio Related Articles: http://home.comcast.net/~msr2000/ http://www.radiowrench.com/sonic/so02004.html http://www.repeater-builder.com/mitrek/mitrek-index.html The above information should get you well on your way and of course we'll be here for personal abuse should you want to ask questions to the group. cheers, s.

[Repeater-Builder] Re: Kenwood TKR850
One of the repeater groups in my area is prepping a TKR-750 for installation. I did the checkout and setup of the machine, and my opinions are mixed. The radio (the TKR-850 is the very similar UHF model) appears to be fairly well-made, but I have some doubts about it being well-designed. ? There have been too many reports of the PA failing to give me a lot of confidence. It may be that the owners of the failed repeaters did not heed the warning that it was rated for continuous (repeater) duty only at 25 watts. Bingo! If you need continuous duty high power... you simply drive an external RF Amplifier designed for the cause. In my opinion, the Motorola RKR1225 is a better repeater, for the same or less (!) money. I've fixed more than one Motorola R1225 repeater with a self de-soldering RF PA Section than had failed in service. As a full service Authorized Kenwood LMR Service Station I've never had to fix a bad TKR Repeater PA in/from anyone who has kept to the mfgrs spec. In fact... I've not ever had to fix a TKR version 2 repeater pa, ever. The TKR-750/850 repeater is an entry-level (low-tier) radio that has a lot of features for the money. entry-level (low-tier)..? want eggs in your beer? When operated within its limitations, it should be a good investment. How about within the manufactures recommendations... Be aware that the TKR-750 is not really intended for operation in the 2m band, and a 600 kHz split may result in higher than expected desense due to internal leakage. I can sell you a TKR-750 designed to operate within the two meter band. So far I've not received any reports of desense problems in any of the many repeaters I've sent out the door. The unit I tested did not have courtesy beep, but it did have built-in CWID. In Amateur Radio Service, both the above are most often provided by an external amateur radio repeater controller connected to the rear I/O jack. In stand alone applications the courtesy beep is much less desired over a CW ID'er. One can easily tack an external courtesy beep tone gen circuit to the back if you need the roger beep acknowledgment after each transmission. s.

RE: [Repeater-Builder] Looking for 220 Repeater Antenna [1 Attachment]
Mike, If your repeater application does not absolutely require an omnidirectional antenna, you might consider the Astron Wireless model 220-4H Yagi antenna, info attached. A modest-gain Yagi has a better vertical pattern than most fiberglass omni antennas, and is ideal where the repeater site is offset from the desired coverage area. I have a 220-4H antenna on-hand, and I plan to compare its performance to the existing Celwave PD220-8B antenna when the weather is more forgiving on the mountaintop site. I will install a remotely-operated coaxial relay to switch between antennas.

RE: [Repeater-Builder] Looking for 220 Repeater Antenna
That is an interesting concept although I do require basically an omni-directional pattern due to the geography and other forces. - Mike From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Eric Lemmon Sent: Monday, June 01, 2009 8:58 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Looking for 220 Repeater Antenna [1 Attachment] [Attachment(s) from Eric Lemmon included below] Mike, If your repeater application does not absolutely require an omnidirectional antenna, you might consider the Astron Wireless model 220-4H Yagi antenna, info attached. A modest-gain Yagi has a better vertical pattern than most fiberglass omni antennas, and is ideal where the repeater site is offset from the desired coverage area. I have a 220-4H antenna on-hand, and I plan to compare its performance to the existing Celwave PD220-8B antenna when the weather is more forgiving on the mountaintop site. I will install a remotely-operated coaxial relay to switch between antennas.

RE: [Repeater-Builder] what controller to use for repeater and link to be installed 800' in the air?
At 6/1/2009 07:54, you wrote: ff-800 would be my choice if I had the money http://www.rollanet.org/~joeh Kind of a waste for a 1 repeater/no links system - the FF-800 is a 5-port controller. NHRC (http://www.nhrc.net) makes a 1 port controller (NHRC-micro) that's small enough to fit inside just about any repeater radio, is about $580 cheaper. ICS (http://www.ics-ctrl.com) also makes a 2 port controller (Linker IIa) for about the same price, a little more if you need the enclosure. I've worked with both IMO the NHRC-micro is more flexible than the ICS unit for a simple 1 port configuration. Both should be reliable enough for your application, but you can inquire with each manufacturer as to the absolute operating temperature limits. Bob NO6B
[Repeater-Builder] Re:Looking for 220 Repeater Antenna
Repeater BuilderWe are currently using a G7-220 on our repeater. We did have problems with the first one we put in the air. The current one is also supported near the top with a standoff to help stabilize it. We too have been in search of a better antenna for this band. The DB224-JJ is difficult at best to find used. They and most other commercial manufacturers no longer supply them. The ones that do are priced at well over $1000. If anyone has a good one to sell please let me know. Maybe if we could get a order of several at one time we could convince them to do a production run for us as long as the price is reasonable.

[Repeater-Builder] Zetron Question
Can anybody tell me if Zetron still supports the Model 45B Z-PATCH or the Model 38A repeater Panel? I need some/all the chips for them. Or at least the ones that are not available from mouser. Thanks, Jordan

RE: [Repeater-Builder] Re:Looking for 220 Repeater Antenna
My antenna would be a stand alone.no upper support. One of the reasons I more or less wanted a rugged enclosed radome unit. I have used the 4 bay exposed dipole type antenna by Cushcraft some years ago ( not longer in production for 220) and the worked great. But down here in hurricane alley not sure I'd trust it.Have you seen the models by LAIRD? - Mike From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Tim and Janet Sent: Monday, June 01, 2009 11:19 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re:Looking for 220 Repeater Antenna We are currently using a G7-220 on our repeater.

RE: [Repeater-Builder] Looking for 220 Repeater Antenna
Bob, Sounds good but at 700' I could run RG-58 to my mother-in-law and she would work great. All kiddin' aside, there is a HUGE price jump between the G7-220 and what 'appears' to be a solid commercial antenna. But it can get WINDY here in FLA and just want to play it safe. - Mike From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of n...@no6b.com Sent: Tuesday, June 02, 2009 12:03 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Looking for 220 Repeater Antenna At 6/1/2009 07:49, you wrote: Seeing far fewer options for 220 repeater use than most other freq bands, I am turning to the group in hopes of hearing from someone who has had some success with their product of choice.
