[Repeater-Builder] For Sale 3 GE Mastr II Stations ICOMs
Hi All, I have 3 UHF mastr II stations for sale. These are the radio portion only. I do have the heavy power supplies they came with but I highly doubt you want to pay the shipping (if interested please ask) 1) DC75YAS88B (I am going off memory) 100w UHF station that was previously operating in burn in works great. Unit has a set of 2C Icoms on 444.575/449.575 that were redone compensated by ICM. Unit is a 100 continuous duty factory repeater. Unit has a pigtail attached to hook into a Arcom RC-210. I have a full set of cards for this can install them if you want them. Unit only has a 10v regulator card in it presently. Unit also has CG Encode (factory DIP switch) / Decode (Versatone) I would like to get $300 OBO (you must pay shipping!) 2) SC65UAS88B (Received as a trade was working 450-470mhz 60w continuous duty. Unit has a fan installed in the PA cover. Unit has not been tested by me but was removed in working condition. Unit may have 2C Icom's installed.

RE: [Repeater-Builder] PL vs. DPL
I have to agree with Eric on this one. I have set up the DPL on the output of the repeater different than the input so it's harder to find the DPL code.

RE: [Repeater-Builder] Alcatel Isolator Panel * 148-164 Mhz
As Bob, NO6B mentioned below, a properly designed wideband VHF isolator can cover the whole VHF highband spectrum. A properly aligned tunable version in either VHF or UHF, 98% of the time, will have lower forward insertion loss, higher reverse isolation and better return loss numbers, all very desireable attributes. Although a wideband version may sound nice, remeber it is a comprise in performance.

When any manufacturer states that his model xxx is available for 136-174 MHz (for example), it does NOT mean that you can field-tune that product to operate anywhere within the 136-174 MHz band. It is not often clearly stated that the firm can MAKE an isolator to operate on a fixed frequency within the 136-174 MHz range, but once made, that isolator has a very narrow field-tuning range of perhaps 3 or 4 MHz. They're a little wider than that. I have several isolators originally made for the 151-154 range that tuned down to 145 MHz quite nicely. UHF isolators made for 460-465 MHz typically tune down to 445 MHz with no problems. I wish I had a nickel for every Ham who bought a ferrite isolator that was manufactured to operate at a commercial frequency, but found that it would not work at all in the 2m band. Despite what some folks allege, a ferrite isolator must normally be remanufactured to move its operating frequency more than a few MHz. A case in point: A local radio club was donated a mint-condition Sinclair dual isolator that was tuned to 162.5125 MHz. Such an isolator costs about $550 new. The club shipped the unit to Sinclair for a factory rebuild to operate at a 147 MHz frequency. It cost about $250 for this work, but the modified unit worked perfectly at the 2m frequency, and it has a new-unit warranty. There is a lot of precision machining that is required to perform a rework; it is far more than a simple retuning. Anyone who tells you anything different is woefully misguided, and obviously knows nothing about how isolators are constructed! Well, there is such a thing as a wideband isolator. I once had one that covered the entire VHF HB with no tuning. They are typically much bigger than the tunable units, at least at VHF are probably more expensive, hence much rarer of a find. Bob NO6B

[Repeater-Builder] Remote base interface: still looking for a beta tester or two
A couple of months ago I announced that I built a few prototypes of a remote base interface that uses the RBI or generic synchronous serial remote base protocol used in LinkComm SCom controllers to provide full remote base control for Yaesu FT-8500 Kenwood TM-G707 radios. Although some expressed initial interest, I'm now not getting any responses from those individuals. So, I'm re-announcing the availability of a couple of these units. Please e-mail me directly at n...@no6b.com if you're interested. If there is interest I may develop units to interface other radios well-suited for remote base operation such as the Kenwood TR-7950, TM-3530 Yaesu FT-8900. The Kenwoods have poor CTCSS support, but the SCom 7K 7330 can provide CTCSS for those radios, those who own a 7950 know how solid the front end is on that model. None of those models will be easy to interface, but it can be done on the Kenwoods by bringing the 2 of 8 keyboard lines out. Complete control of the FT-8900 should be possible with just one wire run out of the control head connections to the mic packet connectors. Bob NO6B
Re: [Repeater-Builder] PL vs. DPL
You forgot one factor... most ham rigs don't have CDCSS abilities, and like it or not those ARE the rigs of choice for people looking for codes for repeaters since they are easy to reprogram. I would agree CDCSS is more secure for that very reason. I recommended a customer switch to CDCSS from CTCSS, and his 'mystery kerchunk' problems went away. It was much easier than prosecuting the offender (not to mention much more PR friendly to hams in general). There is also the benefit mentioned many times that the shut-off code on CDCSS is standard while CTCSS has at least two formats. Good idea about the cross-coding, too. I've done that many times. There also used to be CDCSS codes that Motorola could not do. It was nice using those to keep Motorola radios out of the customer's fleet. That was, until we switched from GE to Motorola... :-\ Joe M. n...@no6b.com wrote: At 3/4/2009 09:49, you wrote: I have to agree with Eric on this one.

[Repeater-Builder] Re: Alcatel Isolator Panel * 148-164 Mhz
Hi Jim, The ferrite is made by RFS here in California and they use a different construction technique versus what you'd consider a regulator circulator/isolator design. The seller Rich had three different frequency range panels for sale. The first batch were higher range 158 to 174 MHz, the mid range and the low ham range units most people here bought. I bought a lot/most of his higher range panels but I honestly haven't even had time to sweep all the models yet. The ferrite is not field tunable... I'm on a new super mega time sink project and I'll be mighty thin for the next couple of days. I do have some data sheets for the Alcatel Panels but it's more of the physical layout diagrams.
